The following is a detailed explanation from Zhejiang Yipu Copper Stranded Wire Manufacturer: Because copper stranded wire has two types: hard copper stranded wire and soft copper stranded wire. The two are very different and are also different in use.
Copper stranded wire has high hardness, high tensile strength and hardness. It is made of copper by drawing and cold processing. Soft copper stranded wire is formed by heating the residue on the basis of hard copper stranded wire. Compared with hard copper stranded wire, it is soft and elastic and can be bent.
According to the different characteristics of hard copper stranded wire and soft copper stranded wire, it is used in different fields. Hard copper stranded wire is often used in places with high tension requirements, such as distribution lines, building conductors, overhead transmission cables, etc., due to its strong tensile strength, low resistance and good conductivity. Soft copper stranded wire is usually thinner than hard copper stranded wire and has high conductivity and toughness. It is often seen in household wires, and is also suitable for motors as conductors for power cables and communication equipment.
Soft copper stranded wire is usually thinner than hard copper stranded wire and has high conductivity and toughness. Commonly used are household wires, which are also used as conductors for power cables and communication equipment in motors.
There is not much difference between hard copper stranded wire and soft copper stranded wire in function. Manufacturers without application experience can easily overlook the difference. If the wrong one is chosen, it will cause great losses. So you must understand the function and which one is more suitable for the application.
(1) Hard copper stranded wire: Hard copper stranded wire has strong tensile strength, low resistance and good conductivity. It is often used in places where conductivity is required and tension requirements are high, such as distribution lines and conductors in buildings, and cables for power transmission in oral attacks.
(2) Soft copper stranded wire: Commonly used are household appliance wires, which are also suitable for motors as conductors for power cables and communication equipment. The soft specifications of copper stranded wire are 15-7φ 5.12-7φ 5.9-7φ 5, etc. Take 15-7φ 5 as an example, 5 means a steel wire with a nominal diameter of 1.7mm, 7φ 5 means 7 such steel wires form a steel strand, and 15 means 15 such steel strands form a bundle of steel bars. It roughly means "a bundle consists of 15 7-inch steel wires (each steel wire has a total diameter of 5mm.
