Under normal circumstances, BVV2 × 2.5 as the main line, trunk, BVV2 × 1.5 as a single electrical branch, switch line.

The products of wire and cable that meet the requirements of national standards, whether aluminum conductors or copper conductors, are brighter and free of oil. The DC resistance of conductors is in full compliance with national standards, and it has good electrical conductivity and high safety.
