AC power cord is a kind of wire through the higher voltage of alternating current, due to the higher voltage of this kind of wire needs to be standardized to obtain safety certification before official production.
It's structure is mainly composed of the outer sheath, inner sheath, conductor, common transmission conductor copper, aluminum wire and so on; which copper wire AC is the core part of the power cord, is mainly the carrier of the current and voltage, the size of the density of the power cord directly affects the quality of the power cord.
AC power cord is an accessory of electrical appliances, but the use of electrical appliances plays an important role; we all know that in the use of electrical appliances need to be plugged into the power cord to be able to use, in the event that the power cord is broken, then the entire appliance can not be used, and may even be scrapped.
With the continuous development of electronic technology, a variety of electronic devices are used in our lives, and these electronic devices are inseparable from the power cord transmission role.
Role performance
Power cord for home appliances, although only accessories, but the use of home appliances plays a vital role, if the power cord is bad, then the whole appliance can not be used. Home power cord should be used BVV2 × 2.5 and BVV2 × 1.5 type of wire.
BVV is the national standard code for copper sheathed wire, 2 × 2.5 and 2 × 1.5 represent 2 cores 2.5 mm2 and 2 cores 1.5 mm2 respectively. In general, 2 × 2.5 to do the main line, trunk line, 2 × 1.5 to do a single appliance branch line, switch line. Single-phase air-conditioning line with BVV2 × 4, with a special ground line.
