Described conductor uses the preferable copper conductor of fire resistance, if stranded by carried interest copper wire, has good pliability, it is thus possible to ensure that cable core is not likely to produce fracture in BENDING PROCESS simultaneously.
Described flame retardant coating uses that inorganic mineral insulation band is wrapped makes, and flame retardant coating act as under hot conditions insulation, and refractory temperature can reach more than 1000 degree, it is ensured that plays the insulating effect to core under the high temperature conditions and ensures that the normal power-up of core is run simultaneously.
Described insulating barrier uses crosslinked polyethylene to make, crosslinked polyetylene insulated is to utilize chemically or physically, cable insulation polyethylene molecule is made to be changed into main body network molecular structure by linearity molecular structure, the most thermoplastic polyethylene is changed into heat cured crosslinked polyethylene, thus it is greatly improved its thermostability and mechanical performance, decrease its contractility so that it is not re-melting after being heated, and maintain excellent electric property.Therefore, crosslinked polyetylene insulated have good superiority in heat-resisting, mechanical properties, so that insulating barrier has the performance such as thermostability and cut resistant.
Described lapping layer is formed by glass fiber tape is wrapped.
Described implant is glass cord, owing to glass cord is to form through special process braiding, there is the main performances such as corrosion-resistant, high intensity, can be used for the aspects such as insulant such as motor, instrument, electrical equipment, being more uniformly stressed of core is respectively organized so that the intensity of cable increases during can ensure that cable distortion.
Described rubber layer is Ceramic silicon rubber layer.
Described flame-retardant expanded layer is latticed, expanded material in flame-retardant expanded layer is when temperature is higher than 200 degree, start foaming, temperature more high-foaming speed is the fastest, and foaming and intumescing coefficient reaches 20 times, and the bubble that expanded material sends has the heat-insulating capability of excellence, if by fire location, the bubble sent can fill up rapidly near fire location, makes fire extinguish due to anoxia, thus has reached the purpose preventing cable on fire.
Described oversheath uses halogen-free and low-smoke flame-retardant polyolefin sheathed material, is made by crowded tubular type expressing technique, and such oversheath can form the carbon shell of porous when burning, thus plays heat-blocking action.
Compared with prior art, this utility model has the beneficial effect that by arranging multiple structure so that the construction of cable of the present utility model is perfect, diverse in function and wear-resisting durable;Remain to play fireproofing function under conditions of voltage is higher;Cable core has good flexibility, it is thus possible to ensure that cable core is not likely to produce fracture in BENDING PROCESS;Flame retardant coating act as under hot conditions insulation;Implant is each during ensureing cable distortion organizes being more uniformly stressed of core so that the intensity of cable increases;The bubble that expanded material in flame-retardant expanded layer sends can fill up rapidly near fire location, makes fire extinguish due to anoxia, thus has reached the purpose preventing cable on fire;Oversheath can form the carbon shell of porous when burning, thus plays heat-blocking action;By the protective effect at high temperature under high pressure of cable different layers so that this utility model has more prominent performance.
