Flexible cable for communication power supply

Abstract

The invention discloses a flexible cable for a communication power supply. The flexible cable comprises a circular high-intensity carbon fiber core, Z-shaped conductors are twisted at the external surface of the circular high-intensity carbon fiber core and form an inner conducting layer, trapezoidal conductors are twisted at the external surface of the inner conducting layer and form an outer conducting layer, a polyethylene insulating tape wraps the external surface of the outer conducting layer, a halogen-free polyolefin elastomer insulating layer wraps the external surface of the polyethylene insulating tape, and an adhesive filling portion is arranged in an aluminum alloy layer and placed among carbon fibers. The adhesive filling portion is composed of 100 parts of maleic anhydride, 15-20 parts of butyl acrylate monomer, 20-30 parts of isooctyl acrylate, 8-10 parts of n butanol, 2-3 parts of dibenzoyl peroxide, 1.5-2.5 parts of triethylene tetramine, 1-3 parts of graphite particles, 3-5 parts of aluminum powder and 8-12 parts of diatomite by weight. The flexible cable is high in tensile intensity, current carrying capacity and flexibility, easy to bend, and tight in structure; and the minimal bending radius is reduced to 3 times of the cable diameter.

Description

technical field [0001] The invention relates to a communication power cable, in particular to a 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 flexible cables for communication power supplies have corresponding technical effects, they have the following common shortcomings: First, since they are all made of stranded fine copper wires, and this conductor is called a five-category copper conductor by the industry, it is therefore The softness does not meet expectations.

[0003] Although flexible cables for communication power supplies have corresponding technical effects, they have the following common shortcomings: First, since they are all made of stranded fine copper wires, and this conductor is called a five-category copper conductor by the industry, it is therefore Softness does not meet expectations

And due to the poor softness, the bending radius is limited, so when laying in a narrow space, obstructed by immovable objects or even corners, it is easy to affect the construction speed; As the conductor of flexible cables, copper not only has blindness in the rational use of raw materials, but also leads to high manufacturing costs for flexible cables; The labor intensity of medium construction personnel is high, and the labor cost is high

On the other hand, those skilled in the art often think that the filler in the communication power cable only keeps the shape of the cable round, and often ignores that it has a positive impact on the electrical properties of the cable and the external conduction and heat dissipation.
