Thai TIS 166 – Thailand

As part of our global expertise in the manufacture and supply of AC mains power cords, Morvan Trading stock a couple of lines of mainscables for Thailand.  We can offer Thai-C13 and Thai to bare end from our UK warehouse on next day delivery, and other specifications, lengths, colours and end connectors can be produced on demand in the Far East.  For non-stocked items we can offer a stocking agreement, where Morvan Trading manufactures and then holds the products in the UK, ready for delivery on customer call-off.  This also drastically shortens leadtimes and helps to ease cashflow.

Exporting to equipment that need mains power in Bangkok or Phuket?  Need to send the correct pattern plug and cable?  Thailand has a relatively new standard, TIS 166, which is a three pin plug rated up to 16 Amps.

Where are they used?

Where are they used?

Whilst similar in appearance to the Israeli plug and a now obsolete Greek plug, it is not compatible: the Thai plug is only used in Thailand.  However, the same Siamese style hybrid socket is used in surrounding countries including Laos, Cambodia and Vietnam.

Thai TIS 166 – Thailand standard – an overview

The IRAM 2073 standard – an overview

Historically, Thailand used both North American and European style plugs, as imported equipment would normally come with of the two types.  Sockets in Siam originally only accepted one type or the other, but hybrid sockets were then designed that accepted both types.  The live and neutral apertures are flat on one side and rounded on the other, to accept flat USA and round Euro pins. 

A third aperture provides a grounding connection for the earth pin of the USA plug; no earthing is provided for European Schuko type plugs.  Thailand operates at 220V 50Hz, which is acceptable for the European style plugs, but the North American style plugs (and the equipment they power) were designed to operate at 110V 60Hz.

Approvals

Approvals To remedy this potentially unsafe disparity in voltages and lack of earthing, the Thai government decided to introduce a new style plug.  The TIS166 was essentially reverse-engineered to fit the hybrid sockets, so has the live and neutral pins of a European plug (4.8mm diameter, 19mm long, 19mm apart, partially insulated) with the earth pin of a USA plug (4.8mm diameter, 21.4mm long, offset by 11.9mm). 

This ensures an earth connection and removes the voltage issue.  As well as an improvement in electrical safety, the introduction has also been seen as a protectionist measure to aid the Thai manufacturing economy by reducing its reliance on imported mains cables and related other products.

The plug and socket were originally described in Thai Industrial Standard TIS 166:2547, but the plug has been revised and updated to TIS 166:2549.  These were issued by the Thai Industrial Standards Institute or TISI.  Dates for Thailand are given in the Buddhist Era, and 2549 equates to 2006 in the Gregorian calendar.  TIS 166-2547 also includes a provision for a solely round pin socket, to eventually phase out the 2 pin and 3 pin flat blade USA plugs in preference for the new style.
