Cable trivia

List of cable specifications and models
Hardware model: insulated conductor BV wire GB standard 10 square wire
System version: Wire system
Cable specifications are the meaning of the representation of the number of cores and cross-sectional dimensions of wires and cables. The wire and cable products used in the power system are mainly overhead
Bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber cables, overhead insulated cables), branch cables (replace some busbars), electromagnetic wires and electrical equipment wires and cables for power equipment.
