Wire conductors. The conductor of the wire should be shiny, and the DC resistance and conductor structure size should meet the requirements of the national standard. The wire and cable products that meet the requirements of the national standard, whether it is an aluminum conductor or a copper conductor, are relatively bright and oil-free, so the DC resistance of the conductor is fully in line with the national standard, with good conductivity and high safety.

How to purchase wires.

Wire specifications. Wire specifications are very important, and generally household power cords should use BVV2 and BVV2 type wires. BVV is the national standard code, which is the copper sheathed wire BVV2 and BVV2, which represent 2 cores square millimeters and 2 cores square millimeters respectively.

In general, BVV2 is used as the main line and trunk line, and BVV2 is used as a single electrical branch line and switch line. BVV2 4 for one-way air-conditioning line, with dedicated ground wire.
