The utility model aims to solve the problems that the wear-resistant layer is oxidized and corroded in the external environment due to insufficient oxidation resistance of the existing cable in use, so that the wear resistance of the existing cable is reduced and the existing cable is easy to wear, and the fire scene rescue difficulty is increased when the existing cable is very easily influenced in a fire scene due to poor heat resistance, so that the existing cable is in electrical conduction failure.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the design is an insulating unsheathed cable of fire-retardant rubber of copper core, and is including two sets of insulation cover and two sets of main copper cable core and inferior copper cable core, and is two sets of be provided with a set of main copper cable core and inferior copper cable core in the insulation cover respectively, it is two sets of the outside cover of insulation cover is equipped with the elastic sleeve, the outside cover of elastic sleeve is equipped with fire-retardant insulating layer, the outside cover of fire-retardant insulating layer is equipped with the wearing layer, the outside of wearing layer is scribbled and is equipped with anti-oxidant coating.
Preferably, the two groups of insulation sleeves are both provided with fixing grooves, and the inner wall of the elastic sleeve is provided with two groups of fixing columns matched with the fixing grooves.
Preferably, the outer walls of the main copper cable core and the secondary copper cable core are provided with insulating layers, and the insulating layers are silicone rubber layers.
Preferably, the flame-retardant and heat-insulating layer is a mica tape.
The utility model provides a copper core flame-retardant rubber insulated unsheathed cable, which has the beneficial effects that: the stability of the two groups of insulation sleeves is maintained by arranging the elastic sleeves, the oxidation resistance of the cable is improved by coating the oxidation-resistant coating on the outer part of the wear-resistant layer, the cable is prevented from being oxidized in the environment, the cable has fire resistance and high temperature resistance by arranging the flame-retardant heat-insulating layer, and power can be supplied well even in a fire scene; the insulativity of the cable is increased by arranging the insulating layer and the insulating sleeve, so that the safety of the cable is greatly improved; the structure is simple, the practicability is strong, and the popularization is suitable.
