Wire and cable number

The wire and cable number represents the model and specification of the wire or cable for electrical equipment. In the representation of the power cable model, different codes (letters or numbers) are used to represent different materials and cable structures. For example, its conductors are aluminum and copper, while L represents aluminum wire, T represents copper wire, and their category and use codes are different.

Model composition of wires and cables

1. Use code - not marked as power cable, K is control cable, P is signal cable; 2. Edge 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 dries to the end; 6. Code of outer protective layer; 7. Special product code - TH wet tropical zone, TA dry tropical zone; 8. Rated voltage - KV.

What is the power of the wire

1. The power consumption should meet the power size of the wire. The power that can be loaded is different with different wire specifications. For example, for household electricity, the selected wire specifications are mainly 1.5 square meters. And the best choice is copper wire, which can accommodate 2200 watts of power. 2. If you choose 2.5 square meters, you can reach 3500 watts. The 4 square meters are 5000 watts, and the 6 square meters are 8800 watts. The other is 10 square meters, which can reach 14000 kilowatts.
