What do ZR-YJV-0.6/1KW-1*10 and ZR-BV-0.45/0.75KW-3*2.5 mean? There are differences between these two types of wires.
There is a mistake in the description; kW should be kV. ZR refers to flame-retardant cables, and if no flame-retardancy rating is specified, it is assumed to be of Class C flame retardancy by default. 0.6/1 refers to the voltage level U0/U, that is, the relative voltage to ground and the voltage between phases; the system voltage used must be lower than this value. In low-voltage systems, the neutral point is usually grounded, which is why 0.6/1-rated power cables are commonly used. YJV denotes cross-linked polyvinyl chloride insulation with a polyvinyl chloride sheath, and 1*10 indicates a single-core cable with a cross-sectional area of 10 mm2. BV refers to insulated wires; the other meanings remain the same
1KW should be K V V
