Wire is the most commonly used and concerned in our lives, and it is an indispensable part of the power overhaul, but about what each color of the wire means, you know? Let's get to know today.
What is the electric wire? Wanzhou wire and cable YJV spot, Chongqing wire and cable factory
Wires refer to conductors that tran***it electric energy. It is divided into bare wires, electromagnetic wires and insulated wires. Bare wire without insulation, including copper, aluminum flat wire, overhead stranded wire and a variety of profiles (such as profiles, busbar, copper row, aluminum row, etc.). It is mainly used for outdoor overhead and indoor busbars and switchgear boxes. The electromagnetic wire is an insulated conductor which generates magnetic field after electrified or induces current in a magnetic field. It is mainly used for motor and transformer circling and other related electromagnetic equipment. Its conductor is mainly copper wire, should h***e a thin insulating layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties. Different insulation materials can be used to obtain different characteristics.

Comparison of advantages and disadvantages between soft wire and hard wire
Wanzhou wire and cable YJV spot, Chongqing wire and cable factory.
Soft wires, also known as sheath wires, are usually wires wound together by multiple strands of copper wire less than 1 mm in diameter. Hard wire is a relatively thick single strand metal conductor, usually more than 1mm directly.
From the nature of wires
The wire of soft wire is thin and soft, easy to turn and wear. But long time is easy to aging, which affects the service life of the whole circuit.
Hard wires are essentially ***aller in cross-section, resistant to short-circuit current impact, and hard wires are not easy to oxidation, life is relatively longer than soft wires. But the hard line itself is hard, and it is difficult to handle the turning pipe.
Do you want to use flexible cord or hard wire for longer life?
Each copper wire of the soft wire is relatively fine, and it is easy to damage and break during installation, thus affecting the conductivity of the wire. On the contrary, the hard line will not be affected by the c***truction process, and it will be much better in reliability and durability.
