Wire and cable refers to materials used for power, communication and related transmission purposes. There is no strict boundary between "wire" and "cable. Generally, products with a small number of cores, a small product diameter, and a simple structure are called wires, those without insulation are called bare wires, and others are called cables; conductors with larger cross-sectional areas (greater than 6 mm²) are called large wires, and smaller ones (Less than or equal to 6 mm²) is called small wires, and insulated wires are also called cloth wires.

Wire and cable mainly includes bare wire, electromagnetic wire and insulated wire for motor and electrical appliances, power cable, communication cable and optical cable.

wire and cable named:

The complete name of the wire and cable is usually more complicated, so people sometimes use a simple name (usually the name of a category) combined with the model specification to replace the complete name, such as "low-voltage cable" on behalf of 0.6/1kV class of all plastic insulated power cables. The type spectrum of wire and cable is relatively perfect. It can be said that as long as the standard model specification of wire and cable is written, the specific product can be clearly defined, but what is its complete name?

The naming of wire and cable products has the following principles:

1. Contents included in the product name

(1) Product application or size category name

(2) Material or type of product structure;

(3) Important or additional features of the product

Nomenclature is basically in the above order, sometimes in order to emphasize important or additional features, features are written before or before the corresponding structural description.
