What are the wires included?

Wires mainly include bare wires, electromagnetic wires, insulated wires, power cables, communication cables and optical cables for electrical appliances. Electric cable refers to the materials used for power, communication and related transmission purposes. There is no strict boundary between "wire" and "cable". Usually, the products with few cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables. 

The conductor with larger cross-sectional area (greater than 6 square millimeters) is called large wire, the smaller conductor (less than or equal to 6 square millimeters) is called small wire, and the insulated wire is also called wiring. 　

There are power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables and so on. They are all composed of multiple wires, which are used to connect circuits, electrical appliances, etc.
