The twisted wire is completed by turning the twisted single wire around the twisted wire axis at equal angular speed and the twisted wire moving forward at even speed. There are two common types of copper and aluminum, copper and aluminum cables can be twisted into a variety of different specifications of cross sections and different types of cable and wire transmission line lithium batteries. Suitable for high output power, single strand of soft copper wire cable skin effect and proximity effect loss is too large. The application of stranded wire can reduce the operating temperature, and the stranded wire has a higher reflective flexibility than the single strand wire of the same section. It is widely used in routes with high "Q" values.
Because there are two types of copper stranded wire and soft copper stranded wire. There are very big differences between the two, and they are also different in use.
Hard copper stranded wire has high tensile strength and high hardness, which is made of copper rashen cold drawing. Soft copper strand is on the basis of hard copper strand according to the heating out in which the residual, compared with hard copper strand is more soft and flexible, can be bent.
Hard copper strand and soft copper strand in the performance of the difference is not very big, no application experience of the manufacturer is very easy to ignore the difference, wrong will lead to a lot of damage, so we must master its performance to master which is more suitable for their own application.
According to the different characteristics of hard copper strand and soft copper strand, they are used in different industries. Hard copper strand because of its strong support force is more firm, small resistor conductivity performance is good, so it is often used for the need for conductivity and the support of the relatively high place, such as the power distribution equipment line and the conductor of the engineering construction, but also the cable line of the air frame transmission and distribution. Soft copper strand is generally thinner than hard copper strand, its conductivity is very high, and elastic. Our most common is the household electrical power transmission line, it is also suitable for electrical machinery, as a conductor of power engineering cable and its communication equipment.
These copper strands are mainly used because copper has excellent electrical conductivity. There is also a kind of copper stranded wire is an insulating layer of copper stranded wire, that is, the copper stranded wire has a ring of insulating glue or plastic outside. The copper strand made like that is mainly the use of the high tension characteristics of the copper strand, which can be used as a unique lock, a brake line on a bicycle or an electric vehicle or a motorcycle. It can also be extended to be used as a rope for drying clothes and so on.
