Wholesale Strapping Wire Harness Winding Retractable Electric Cable Reel Drum Reeling Wire

A wire is composed of one or several flexible wires, wrapped with a light and soft protective layer; A cable is composed of one or several insulated wires, with a tough outer layer made of metal or rubber. Good quality wires are generally within the specified weight range. The commonly used plastic insulated single stranded copper core wire with a cross-sectional area of 1.5 has a weight of 1.8-1.9kg per 100m; 2.5 plastic insulated single stranded copper core wire, weighing 2.8-3.0kg per 100m; 4.0 plastic insulated single stranded copper core wire, with a weight of 4.1-4.2kg per 100m, etc. Poor quality wires have insufficient weight, either insufficient length, or excessive impurities in the copper core of the wires.

Electric wires refer to wires that transmit electrical energy. Divided into bare wire, electromagnetic wire, and insulated wire. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles (such as profile wires, busbars, copper bars, aluminum bars, etc.). It is mainly used for outdoor overhead and indoor busbars and switch boxes.
