The power cord, known as the plug the power cord is a certain length of wire with a plug or the power cord has a plug.

 
Power lines are small appliances; telecommunications, machinery and equipment commonly used accessories, simply, a good equipment, instruments or, as long as the need for electricity, are inseparable from the power cord.

The power cord is a world-wide product, the power cord products to be exported, it must require certification of products, which are exported to the country's power cord must have the appropriate certification. As exports to Europe must have European plug wire VDE certification, exports to the U.S. power cord must have UL certification, exports to the United Kingdom's power cord must have a British BS certification, and export to Australia SAA plug wire must have certification......

Since it is a plus power cord plug wires, when necessary so that must configure the appropriate plugs and wires according to customer requirements. For example, plug: it is 2-pin plug or 3-pin plug connector which country needs, how many amps voltage, current, how much the power; The classification of distribution lines are many: a 2-core wire or 3-wire cord, standards and requirements in different countries have different wires there are different models, such as Europe is marked with H03VVH2-F H05VVH2-F H05VV-F, etc., size also 2x0.75mm2 2x1.0mm2 3x0.75mm2 3x1.0mm2 ...... needs with long lines.

So many specifications and requirements, and clients must be good communication, when necessary, also need to give the customer a sample, let confirmation.

So the structure of the power cord is what? There are three main power line structure parts:
The first part: an outer sheath, the outer protective sheath is generally to protect the inside of the structure is not destroyed; the normal power supply line can be safely used. Outer sheath direct contact with the outside world so the outer sheath generally have insulation resistance, high temperature resistant, cold resistant, oil resistant, wear resistant, toughness, etc.

Part II: Also known as wire insulation jacket, according to the popular name can tell the main role is in use, isolated objects with the current direct contact with the outside world, leading to safe use.

Part III: the inner core, the inner core is the core part of the power cord is connected to a direct contact with electrical current, is a current and electrical media. The inner core material is generally copper, so copper directly affects the quality of the power cord.
