Wire and cable specification

The cable specification is the meaning of the representation of the number of cores and sectional dimensions of wires and cables. The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables), branch cables (replacing part of the bus bars), electro-magnetic wires and electrical equipment wires and cables for power equipment.

Model composition of wires and cables

1. Purpose code - not marked as power cable, K is control cable, P is signal cable; 2. Insulation code - Z oil-immersed paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; 3. Conductor material code - not marked as copper, L as aluminum; 4. Internal protective layer code - Q lead package, L aluminum package, H rubber sleeve, V polyvinyl chloride sheath; 5. Derivative code - D does not drip, P dry insulation; 6. Code of outer protective layer; 7. Special product code - TH wet tropical zone, 8, TA dry tropical zone; Rated voltage - in KV.

Wire and cable differentiation

In fact, there is no strict boundary between "wire" and "cable". Generally, products with small number of cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; Larger conductor cross-section (more than 6 mm2) is called large wire, smaller conductor cross-section (less than or equal to 6 mm2) is called small wire, and insulated wire is also called cloth wire.
