It ensures, needs to carry out all fronts replacement to cable at this time, the cable handling after replacement can cause environmental pollution；In addition cable makes
With being easy to happen burning in the process, and the rate of propagation that burns is fast, and generates a large amount of toxic and harmful gas in burning.
Summary of the invention
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of double-deck exhausted
Edge cable, it can effectively improve the service life of cable, while have good fire resistance, and while being avoided that burning generate it is toxic
Pernicious gas.
The technical scheme adopted by the utility model is a kind of double-insulated cable, including copper core and cable cover(ing), it is described
Cable cover(ing) includes the inner insulating layer successively coated from the inside to the outside, flame retardant coating, external insulation layer and insulating coating, the inner insulating layer
It is coated on copper core outer surface, the outer surface of inner insulating layer is uniformly provided with several inside recess, and recess middle part is fixed with latch segment,
Latch segment center is provided with locking hole along wherein axis direction, and the flame retardant coating is Ceramic silicon rubber band, and flame retardant coating is around interior
The recess corresponding position of the sunk surface of supporting layer and outer surface, the external insulation layer and inner insulating layer is provided with counter sink, counter sink
The interior lock-screw being equipped with locking hole Corresponding matching, lock-screw is locked with locking hole, in the insulating coating inside
Sky, insulating coating is interior to fill full fire resistance fibre.
Preferably, the inner insulating layer is made of polyethylene.
Preferably, the external insulation layer is made of fire-retardant cross-linking radiation polyolefin.
The utility model production cost is low, long service life, and has good fire-retardant, fire resistance, while firing
