Power Line Winding Performance Is Good
- Sep 27, 2017 -


Power lines in accordance with the purpose can be divided into AC AC power lines and DC DC power lines, AC power cord is usually through the higher voltage AC wire, this type of wire due to the need for uniform high voltage standard safety certification can be formally produced. The DC line is basically through the lower voltage of the DC, so the safety requirements and no AC line strict, but for safety reasons, Power Cord the current countries or require uniform security certification.

The structure of the power cord mainly to the outer jacket, inner sheath, conductor, Power Cord the common transmission conductor copper, aluminum wire and other metal.

Outer jacket

The outer jacket is also known as the protective sheath, is the outermost layer of the power cord jacket, this layer of outer jacket plays a protective power line role, the outer jacket has a strong feature, such as high temperature, Anti-natural light interference, winding performance, high life, environmental protection and other characteristics of materials. Inner sheath: inner sheath, also known as the insulation jacket, Power Cord is the power cord indispensable part of the middle structure, insulation sheath with the name of the insulation is to ensure that the power cord power security, so that between the copper and air Will produce any leakage phenomenon, and the insulation sheath of the material to be soft, to ensure a good fit in the middle layer.

Copper wire

Copper wire is the core of the power cord, copper wire is mainly the current and voltage of the carrier, Power Cord the copper wire density directly affects the quality of the power cord. Power cord material is also an important factor in the quality of checks, the number of copper and flexibility is also considered one of the factors.

Inner sheath

The inner sheath is a layer of material that wraps the cable between the shield and the core, usually of polyvinyl chloride or polyethylene. There are low smoke halogen-free material. In accordance with the provisions of the use of technology, so that the insulation will not contact with water, Power Cord air or other objects, to avoid insulation and insulation of the insulation from mechanical damage.

Power cord for home appliances, although only accessories, but the use of home appliances is playing a vital role, if the power cord is broken, the whole electrical appliances can not be used. Household power lines should use BVV2 × 2.5 and BVV2 × 1.5 models of the wire. Power Cord BVV is the national standard code for the copper jacket line, 2 × 2.5 and 2 × 1.5, respectively, on behalf of 2 core 2.5 square millimeters and 2 core 1.5 square millimeters. Under normal circumstances, 2 × 2.5 do the main line, trunk, 2 × 1.5 to do a single electrical branch line, switch line. Single-phase air-conditioning line with BVV2 × 4, reprovision dedicated ground.
