Wire and cable x

The meaning of X in wires and cables represents rubber insulation

Wire and cable structure sequence

Insulating material, conductor material, inner protective layer and outer protective layer.

Letter code of wire and cable

The model of wire and cable is like a label. We can identify the conductor material, application range, insulation type, structural characteristics and laying site of wire and cable through the model.    Conductor representative: L represents aluminum, T represents copper.    Cable representatives: B represents insulated cable, R represents insulated flexible cable, Y represents mobile flexible cable, H municipal telephone cable, K control cable, P signal cable.    Insulation representative: V represents PVC, X represents rubber, Y polyethylene, YJ represents cross-linked polyethylene, Z represents paper insulated cable.    The inner sheath represents: V represents PVC sheath, Y represents polyethylene sheath, L represents aluminum sheath, Q represents lead sheath, H represents rubber sheath, and F represents neoprene sheath.    The armor layer represents: 2 represents double copper pipe, 3 represents thin steel wire, and 4 represents thick steel wire.    Generally, there are no 2 digits after the model, which means there is no armor layer and no outer protective layer; If there are numbers, the first number represents the armor, and the second number represents the outer protective structure.

Wire and cable identification model and specification

First look at the model and then the specification and rated voltage. VV32-3 * 50 refers to the copper core PVC insulated fine steel wire armored polyethylene chloride sheath, and the rated voltage is 10kv three-core power cable, with a nominal cross-sectional area of 50 square meters. YJV22-3 * 150 refers to copper core PVC insulated fine steel wire armored PVC sheath, three-core cable with rated voltage of 0.6/1kv, and sectional area of 150 square meters.
