Problems solved by technology

[0003] Although not limited to the flexible cables for communication power sources listed above, although each has corresponding technical effects, there are the following common shortcomings: First, since they are all made of twisted fine copper wires as conductors, and this conductor is known as Class 5 copper conductors, so the softness does not meet the expected requirements
And due to the poor softness, ...

Abstract

The invention discloses a high-carrying-capacity flexible cable for a communication power supply. The high-carrying-capacity flexible cable comprises three conductive cores, a plurality of first circular aluminum conductors which form an inner conductive layer, a plurality of second circular aluminum alloy conductors which form an outer conductive layer, and a polyethylene insulating belt which wraps the outer surface of the outer conductive layer; a fireproof flame-retardant layer wraps the outer surface of the polyethylene insulating belt, comprising mica paper, a first glass fabric and a second glass fabric; the mica paper is adhered to the first glass fabric and the second glass fabric through adhesive layers; a glass tape wraps the outer surface of the fireproof flame-retardant layer; a polyolefin insulating protecting sleeve layer wraps the outer surface of the glass tape; a warping tape wraps the outer surfaces of the three conductive cores; an insulating protecting layer wraps the outer surface of the warping tape. According to the high-carrying-capacity flexible cable, the conductivity is improved, and the carrying capacity is increased by about 10%; the cable is non-combustible, high in heat resistance, tight and difficultly to breath, and therefore, the high temperature resistance of the cable is improved.

Description

technical field [0001] The invention relates to a communication power cable, in particular to a high-carrying-capacity flexible cable for communication power. Background technique [0002] With the rapid advancement of 4G applications, flexible cables for communication power supplies used in base station construction have been widely promoted and applied, mainly for power connections in switch cabinets. Flexible cables for communication power supply not only require good flexibility to facilitate laying in narrow spaces or similar situations, but also require ideal flame retardancy to meet the requirements for use in occasions with strict fire ratings. [0003] Although not limited to the flexible cables for communication power sources listed above, although each has corresponding technical effects, there are the following common shortcomings: First, since they are all made of twisted fine copper wires as conductors, and this conductor is known as Five types of copper condu...
