Abstract
The utility model provides a flame-retardant fireproof unidirectional-twisting ultra-flexible cable for a communication power supply, which comprises a cable core and an outer jacket. A plurality of lead wires are arranged in the cable core, insulating layers are wrapped outside conductors formed through twisting of copper wires so as to form the plurality of lead wires, flame-retardant fillers are respectively arranged between the lead wires, fireproof layers are respectively arranged between the conductors of the lead wires and the insulating layers, and a flame-retardant belting layer is arranged between the cable core and the outer jacket. The conductors of the lead wires adopt the unidirectional twisting structure of wire bundling twisting and composite twisting of single copper wire. With good flame-retardant as well as fireproof performances and high flexibility, the ultra-flexible cable is convenient for laying in a communication room, cannot be spread for combustion once a fire hazard is incurred, and can adapt to the using requirement in the communication room.
Description
Technical field
The utility model relates to a kind of power cable, especially the communication power supply flexible cable.
Background technology
Communication power supply generally lays in communications equipment room with flexible cable, requires to have good fire-retardant, fire resistance, and flexibility is good, and the existing communication power supply can not adapt to the requirement of using with the structure and the performance of flexible cable in communications equipment room.
Summary of the invention
In order to overcome the deficiency of existing communication power supply with flexible cable, the purpose of this utility model provides a kind of communication power supply and twists super flexible cable in the same way with flame-retardant.
A kind of communication power supply that the utility model provides twists super flexible cable in the same way with flame-retardant, comprise cable core and oversheath, have several leads that constitute by stranded conductor that forms of copper wire and outsourcing insulation in the cable core, between several leads, be provided with fire-retardant filler, between the conductor of lead and insulating barrier, be provided with flame retardant coating, between cable core and oversheath, be provided with fire-retardant belting layer.
Conductor of the present utility model adopts the synnema strand of copper monofilament and twists equidirectional stranded structure again, can effectively increase the contact-making surface between monofilament and the monofilament like this, can reduce contact resistance, can increase the pliability of cable again.
The beneficial effects of the utility model are: have good fire-retardant, fire resistance, flexibility is good, lays in communications equipment room conveniently, in case run into fire, cable can propagating combustion, can adapt to the requirement of using in communications equipment room.
