At.
Preferably, the foil woven cloth flame-retardant layer include the aluminium foil layer set gradually from top to bottom, it is fire-retardant glue-line, fire-retardant
Base fabric, fire-retardant glue-line and aluminium foil layer, the aluminium foil layer use the high-purity aluminium foil of 99% aluminium content, and fire-retardant glue-line, which uses, to be added
Added with the polyurethanes composite glue of calcium carbonate, flame retardant woven layer of cloth uses low-pressure high-density polyethylene woven cloth, fire-retardant
The upper and lower surface of base fabric is compound by polyurethanes composite glue and aluminium foil layer.
Compared with prior art, the beneficial effects of the present invention are：
1, the present invention is equipped with fiber unit, can be used in " three to power cable into trip temperature, transmission load real time monitoring
Net fusion "；Silk thread beam surrounds the optical fiber directly dragged, and optical fiber will not be pulled off, and silk thread beam has also carried out effective protection to optical fiber, is adding
It will not be extruded when work, laying, especially when cable is run, be bound to generate heat and expand, it is ensured that have space light
