In the inside of protective layer, the surface fixing sleeve of the protective layer is connected to radiation protective layer, and the surface of the radiation protective layer is fixedly attached
There is flame-retardant layer, the surface fixing sleeve of the flame-retardant layer is connected to wearing layer；The mica belt is the dedicated mica tape of cable, and mica
The shape of band is on paper slip or the cylindric surface for being directly bonded in insulating layer；The side-glance shape of the ball be it is cylindric,
The columned ball shape size is adapted with the shape size of cable core；The filled layer is the resistance of siliceous inorganic filler type
Agent is fired, the insulating layer is the polymer of tetrafluoroethene；The radiation protective layer is EMI electromagnetic shielding plastic, with a thickness of three to five
Millimeter, the flame-retardant layer are flame retardant rubber, and with a thickness of four to six millimeters, the wearing layer is with a thickness of six to eight millimeters；It is described resistance to
The inside of mill layer is inlaid with steel loop, and the diameter of the steel loop is greater than the diameter of wearing layer.
Preferably, on the surface of the every 20 lis of spaced set wearing layers of the steel loop.
Compared with prior art, the present invention provides a kind of high-intensitive low halogen cigarette power cable of insulation high-temperature-resistant, have with
Lower the utility model has the advantages that the present invention, which passes through, is arranged mica belt, mica belt directly winds or is socketed on the insulating layer, carries out to cable core
It is fire-retardant, while can have certain buffering resistance to compression effect by ball and filled layer, so pass through radiation protective layer, flame-retardant layer and
Wearing layer so that cable core has certain radiation protection, fire-retardant and wear-resisting effect in inside, while can slow down surface by steel loop and drag
Damage in the case of drawing, and not halogen crosslinked polyethylene fire proofing is filled in the flame retardant rubber inside flame-retardant layer, no
Only there is better flame-retarding characteristic, and environmental protection, so that reducing halogen cigarette, further enhance the high-intensitive low halogen of the insulation high-temperature-resistant
The practicability of cigarette power cable.
