Cable refers to have metal composite material armored cable protective layer of cable, cable plus armored cable layer of the purpose of the cable in addition to improve compressive strength, tensile strength and other mechanical equipment maintenance to increase the duration of use, but also according to the shielding off the maintenance to enhance the ability of the cable anti-interference ability.
Common armored cable raw materials are strip steel, stainless steel wire, aluminum coil, aluminum alloy tube, etc., in which the strip steel, stainless steel wire armored cable layer with high magnetization strength, has a very good electromagnetic shielding effect, can be used to resist the influence of low frequency, and can make the cable buried directly laying and can be exempted from the threading pipe and cheap in the specific application of the more.
Not the same specifications and models not the same number of copper wire according to a certain order and stranding distance stranded together, it becomes a large diameter electrical conductor, this type of stranded wire diameter stranded electrical conductor than the same diameter size of a single copper wire is more soft, to make the cable bending characteristics of a good, swing test is not easy to break, for some of the soft cable has a provision (such as diagnostic level cable) is more very easy to Do regulations.
From the characteristics of electrical equipment: electrical conductors plugged in, because the resistor consumes electromagnetic energy and hot. The accompanying rise in temperature jeopardizes the service life of the raw material characteristics of the cable jacket and protective coating. In order to better make the cable line efficient operation, should expand the cross-section of the conductor, but a large cross-section of a single transmission line is not conducive to bending, poor flexibility, is not conducive to the production and manufacture of transportation and installation of laying. From the physical properties and the provisions of flexibility, stability, multiple single wire twisted together in the stranded wire, you can resolve the conflict.
