Types of sockets in hotels of tourist countries (UAE, Cyprus, Thailand, Vietnam, Italy and others). Types of electrical sockets around the world Voltage in European sockets

Mains voltage, sockets, plugs, adapters and adapters - this is what every tourist who goes to an unfamiliar country should think about. This is especially true in modern world when the vast majority of people travel with their personal electronic devices that require constant recharging - from cameras and mobile phones to laptops and navigation systems. In many countries, the issue is solved simply - with the help of an adapter. However, plugs and sockets are only half the trouble. The mains voltage can also be different from the usual one at home - and you should know and remember this, otherwise you can ruin the device or charger. For example, in Europe and most Asian countries, the voltage varies from 220 to 240 volts. In America and Japan, it is half as much - from 100 to 127 volts. If a device designed for American or Japanese voltage is inserted into a European socket, it will burn out.

SOCKETS AND PLUGS

There are at least 13 different plugs and sockets in the world.

Type A

This type is designated as Class II. The plug consists of two parallel pins. In the Japanese version, the contacts are the same size. In the American one, one end is slightly wider than the other. Devices with a Japanese plug can be used in American sockets, but vice versa will not work.

Type B
for North and Central America and Japan

This type is referred to as Class I. The international designation for American type B is NEMA 5-15, Canadian type B is CS22.2, n°42 (CS = Canadian Standard). The maximum current is 15 A. In America, type B is very popular, in Japan it is much less common. Often, residents of old houses with type A sockets, acquiring new modern electrical appliances with type B plugs, simply “bite off” the third grounding contact.

Type C
used in all European countries except UK, Ireland, Cyprus and Malta

International designation - CEE 7/16. The plug consists of two contacts with a diameter of 4.0-4.8 mm at a distance of 19 mm from the center. The maximum current is 3.5 A. Type C is an obsolete version of the newer types E, F, J, K and L now used in Europe. All Type C plugs are ideal for new sockets.

Type D
used in India, Nepal, Namibia and Sri Lanka

International designation - BS 546 (BS = British Standard). It is an obsolete British style plug that was used in the metropolitan area until 1962. The maximum current is 5 A. Some type D sockets are compatible with type D and M plugs. Type D sockets can still be found in old houses in Great Britain and Ireland.

Type E
used mainly in France, Belgium, Poland, Slovakia, Czech Republic, Tunisia and Morocco

International designation - CEE 7/7. Maximum current - 16 A. Type E is slightly different from CEE 7/4 (type F), which is common in Germany and other countries of central Europe. All Type C plugs fit perfectly into Type E sockets.

Type F
used in Germany, Austria, the Netherlands, Sweden, Norway, Finland, Portugal, Spain and Eastern European countries.

International designation CEE 7/4. This type is also known as "Schuko". The maximum current is 16 A. All type C plugs are ideal for type F sockets. The same type is used in Russia (in the USSR it was designated as GOST 7396), the only difference is that the diameter of the contacts adopted in Russia is 4 mm, in while in Europe, 4.8mm contacts are most commonly used. Thus, Russian plugs easily fit into wider European sockets. But the plugs of electronic devices made for Europe do not fit into Russian sockets.

Type G
used in UK, Ireland, Malaysia, Singapore, Hong Kong, Cyprus and Malta.

International designation - BS 1363 (BS = British Standard). The maximum current is 32 A. Tourists from Europe visiting the UK use ordinary adapters.

Type H
used in Israel

This connector is marked with the symbols SI 32. The type C plug is easily compatible with the type H socket.

Type I
used in Australia, China, New Zealand, Papua New Guinea and Argentina.

International designation - AS 3112. Maximum current - 10 A. Sockets and plugs of types H and I do not match. The sockets and plugs used by the people of Australia and China are well matched.

Type J
only used in Switzerland and Liechtenstein.

The international designation is SEC 1011. The maximum current is 10 A. Regarding type C, the type J plug has one more contact, and the socket has one more hole. However, Type C plugs will fit Type J sockets.

Type K
only used in Denmark and Greenland.

The international designation is 107-2-D1. The Danish socket accepts CEE 7/4 and CEE 7/7 plugs as well as Type C sockets.

Type L
used only in Italy and very rarely in North African countries.

International designation - CEI 23-16 / BII. The maximum current is 10 A or 16 A. All type C plugs fit L type sockets.

Type M
used in South Africa, Swaziland and Lesotho.

Type M is very similar to type D. Most type M sockets are compatible with type D plugs.

ADAPTERS, CONPERTORS, TRANSFORMERS

In order for the plug from your device to be inserted into an outlet in a particular country in the world, an adapter or adapter is often needed. Universal adapters are on sale. In addition, in good hotels, you can usually ask for an adapter at the hotel reception.

• Adapters do not affect the voltage and flow of electricity. They only help to match one type of plug to another type of socket. Universal adapters are most often sold in duty-free shops. Also in hotels you can often ask for an adapter for temporary use from the maids.
• The converters are able to provide a short conversion of the local parameters of the electrical network. For example, they are convenient on the road, where they allow you to use a hair dryer, iron, electric shaver, kettle or small fan for just as long as you need. At the same time, they are small in size, and due to the weak hardware base, it is not recommended to use them for more than one and a half to two hours in a row, since overheating of the converter can lead to damage to the electrical appliance using it.
• Transformers are more powerful, large and expensive voltage converters capable of maintaining long-term operation. Transformers without restrictions can be used for such "serious" electrical appliances as radios, audio players, chargers, computers, TVs, etc.

Most modern technology, including laptops and chargers, is suitable for use in both networks - both 110 and 220 V - without the use of a transformer. Only the appropriate adapters for plugs and sockets are needed.

VOLTAGE AND FREQUENCY

Of the 214 countries in the world, 165 countries use 220-240 V (50 or 60 Hz), and 39 countries use 100-127 V.

In Europe, the voltage in the electrical network varies from 220 to 240 V, in the USA and Japan - from 100 to 120 V - why? Is it really just to create problems for tourists who are forced to carry adapters with them or look for it already upon arrival, so as not to let the phone “die”?
When it comes to electricity, globalization can be forgotten. Even in the European Union, where one currency circulates, there are different electrical outlets. The reason for this is the historical factor.

In the era of electrification, inventors from different countries offered their own options for optimal sockets; different types of electric generators were built around the world. And the national companies involved in the installation of electrical networks supplied their devices suitable for these networks. Accordingly, different types of plug connectors and sockets were introduced and their own networks were designed. The developments of other countries were completely ignored.

Influenced the development of sockets and the availability of materials. For example, during the Second World War in Great Britain they came up with a three-prong plug with a short copper fuse. This design made it possible to save copper reserves for military needs.

Now, according to one classification, 12 types of sockets are distinguished, according to another - 15. Moreover, sockets of one type sometimes accept plugs of another. However, having learned that in the country where you are going, the same type of outlet as at home, do not rush to rejoice! This solution is only half the problem. In different parts of the world, the voltage and frequency of the current may vary.

Classification of types of sockets and plugs in different countries of the world

The most common are two standards: European - 220-240 V at a frequency of 50 Hz and American - 100-127 V at a frequency of 60 Hz. You should not check what will happen if an electrical appliance operating from 100-127 V is plugged into a socket with 220-240 V.

In some countries, you have to keep your eyes open at all. For example, in most parts of Brazil 127 V is used, but in the north of the country 220 V is found. And in Japan, the voltage is the same everywhere - 110 V, the frequency is different: 50 Hz is used in the east, 60 Hz in the west. The reason is simple: first, German-made generators with a frequency of 50 Hz were purchased for Tokyo, and shortly after that, American generators with a frequency of 60 Hz were supplied to Osaka.

Perhaps someday a single standard will be adopted. A universal socket for all types of plugs has already been developed. But for now it's up to everyone whether to install it or not. In addition, you first need to come to a single voltage standard. And this rests on the huge financial costs of re-equipment and re-equipment of transformer substations, replacement of sockets and plugs.

Something about sockets and their use from my own experience

When traveling abroad, the format of the outlet and the voltage in the network are important, because each of us will need to charge our mobile phone, laptop or tablet. Most power supplies for electronic devices such as laptops, chargers, mobile devices, camcorders and cameras have a universal power supply, so they are able to operate at a supply voltage of 100 to 240 volts, and a frequency of 50 or 60 Hz.

There are two voltage standards in the world: European - 220-240V and American 100-127V. And two AC frequency standards: 50Hz and 60Hz. USA, Japan and most South American countries use 100-127V 60Hz. The rest of the world mainly uses European 220-240V 50Hz. In addition, there are several countries in the world with different voltage and frequency variations, such as the Philippines, where the voltage is 220-240V with a frequency of 60 Hz.

Electrical outlet standards have developed independently in most countries, so for the most part, plugs and sockets from different countries are not compatible with each other.

Type M

Used in South Africa, Swaziland and Lesotho.

Type M is very similar to type D. Most type M sockets are compatible with type D plugs.

It's really very inconvenient. Okay, before people traveled a little around the world, now it's practically not a luxury. Remember, when household appliances assembled in Europe began to arrive in Russia, how many problems there were with our Soviet sockets. Bought adapters, they burned. Only not so long ago finally got rid of this problem.

I was in Cyprus in the spring - there are quite unusual British sockets. In a small town in Russia, you can’t buy adapters; upon arrival, you had to run around there, look for them, overpay. Soon I'm going to the Dominican Republic - and there again there are other sockets, American ones (sort of). Adapters will again have to be bought on the spot and not in 1 copy.

And all why...

In the era of electrification, inventors from different countries offered their own options for optimal sockets; different types of electric generators were built around the world.

First, the struggle of technologies at the dawn of the development of electricity left its mark. We are talking about the opposition of Thomas Edison and Nikola Tesla in the creation of DC and AC networks, respectively. Although we know that AC power plants eventually won out, the DC infrastructure built in the US up to the 1920s (and in Stockholm up to the 1950s) has to be maintained and used right up to the present day. .

Secondly, many inventors offered their own options for optimal (in their opinion) sockets. For example, in 1904, the American inventor Harvey Hubbel received a patent for the first electrical outlet. By its design, it was a kind of adapter for an electric chuck-plug. The adapter was screwed into the cartridge instead of a light bulb, and some electrical appliance was connected to it.

The German engineer Albert Büttner created the "Euro socket" known to us today in 1926. And the first socket with grounding was created by Philippe Labre in 1927.

And the national companies involved in the installation of electrical networks supplied their devices suitable for these networks. Accordingly, different types of plug connectors and sockets were introduced and their own networks were designed. The developments of other countries were completely ignored.

Influenced the development of sockets and the availability of materials. For example, during the Second World War in Great Britain they came up with a three-prong plug with a short copper fuse. This design made it possible to save copper reserves for military needs. Curiously, the use of the 3-pin plug in the UK was in stark contrast to the rest of Europe and even North America, where 2-pin plugs were widely used and also differed in design, all due to the lack of communication in the early days. power supply development.

Now, according to one classification, 12 types of sockets are distinguished, according to another - 15. Moreover, sockets of one type sometimes accept plugs of another. However, having learned that in the country where you are going, the same type of outlet as at home, do not rush to rejoice! This solution is only half the problem. In different parts of the world, the voltage and frequency of the current may vary.

Classification of types of sockets and plugs in different countries of the world

The most common are two standards: European - 220-240 V at a frequency of 50 Hz and American - 100-127 V at a frequency of 60 Hz. You should not check what will happen if an electrical appliance operating from 100-127 V is plugged into a socket with 220-240 V.

Perhaps someday a single standard will be adopted. A universal socket for all types of plugs has already been developed. But for now it's up to everyone whether to install it or not. In addition, you first need to come to a single voltage standard. And this rests on the huge financial costs of re-equipment and re-equipment of transformer substations, replacement of sockets and plugs.

* Voltage 100-127V @ 60Hz is used by USA, Canada, Japan, Mexico, Cuba, Jamaica, part of Brazil and other countries.

* Voltage 220-240 V with a frequency of 50 Hz is used in most other countries, but even with the same parameters, the type of sockets can vary greatly.

Here short description some of them:

Types A and B - American socket

Type B differs from A in that it has a third hole, which is for the ground pin. Such sockets, as you might guess from the name, were invented in the USA and distributed in North, Central and partly South America, as well as Japan and some other countries.

Types C and F - European socket

Just like A and B, types C and F differ only in the presence of grounding - F has it. The European socket is used in most EU countries, as well as in Russia and the CIS, Algeria, Egypt and many other countries.

Type G - UK socket

In the UK, the socket has three flat holes, and this design appeared for a reason. The fact is that during the Second World War the country experienced a shortage of copper. Therefore, a plug with a short copper fuse and three plugs was developed. In addition to Great Britain, the same socket is used in Cyprus, Malta, Singapore and other countries that have experienced the influence of the British Empire.

Type I - Australian socket

This type of outlet can be found not only in Australia, but also in New Zealand, Fiji, the Cook Islands, Kiribati, New Guinea, Samoa and sometimes in China, where types A and C are also common.

Type H - Israeli socket

Type H is used only in Israel and Palestine, and the pins of the plug can be either round or flat, depending on when the device was manufactured. The flat shape of the outlet was in the old technique, but the new outlets fit two options.

Type K - Danish socket

This outlet can easily claim to be the "friendliest" in the world - its design resembles a smiling face. In addition to Denmark and Greenland, which is part of it, type K is used in Bangladesh and the Maldives - however, several types of sockets are common there at once.

Fortunately, all these differences will not spoil your vacation or business trip - you just need to purchase a suitable adapter in advance.
