Aluminum alloy low voltage tensile frequency conversion cable

Abstract

The invention discloses an aluminum alloy low voltage tensile frequency conversion cable. The cable is mainly composed of a polytetrafluoroethylene glass silk sheath, a metal structure layer, a braided copper shielding layer, ground wire cable cores, aluminum alloy conductors, control cable cores and a phase line cable core. A circle of aluminum alloy conductors are evenly arranged outside each ground wire cable core, the polytetrafluoroethylene glass silk sheath is wrapped on the ground wire cable cores and the aluminum alloy conductors, a ceramic powder polyvinyl chloride shielding layer and a fluororubber sheath are sequentially wrapped on each control cable core from inside to outside, the phase line cable cores are arranged in a thermoplastic rubber isolation layer, the braided copper shielding layer extrudes the two fluororubber sheaths comprising the control cable cores, the two fluororubber sheaths comprising the aluminum alloy conductors and the thermoplastic rubber isolation layer together, and the metal structure layer and the polytetrafluoroethylene glass silk sheath are sequentially wrapped on the braided copper shielding layer. The aluminum alloy low voltage tensile frequency conversion cable has the advantages of being resistant to interference, tensile and long in service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to an aluminum alloy low-voltage tension-resistant frequency conversion cable. Background technique [0002] At present, in industrial electricity consumption, frequency converters are more and more widely favored, and the use characteristics of energy saving and safety have gradually been recognized by the market. However, the existing frequency conversion cables have short service life, low tensile coefficient, and weak anti-interference ability. With the widespread promotion of frequency converters, traditional cables cannot meet the use characteristics of high electromagnetic harmonics, and it is urgent to develop a cable that can overcome the above shortcomings. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide an aluminum alloy low-voltage tension-resistant frequency conversion cable. ...
