There are two types of copper stranded wire: hard copper stranded wire and soft copper stranded wire. The two are very different, and the use is also different: according to the different characteristics of the hard copper strand and the soft copper strand, they are used in different fields. Hard copper stranded wire because of its strong tensile strength compared to the knot, small resistance and good conductivity, so it is often used in places that need to conduct electricity and have relatively high tension requirements, such as distribution wires and building conductors, and drainage power transmission cables. Soft copper strand is usually thinner than hard copper strand, its electrical conductivity is particularly high, and toughness. Our most common is the household electrical wire, it is also used in electrical machinery, as a conductor of power cables and communication equipment. Hard copper stranded wire has high tensile strength and high hardness. It is made of copper tensile cold processing. Soft copper strand is based on hard copper strand by heating out the residual, compared with hard copper strand is soft and flexible, can be bent.
