It is cumulative to add.
During installation, transport and use, cable surface is easily worn cable, the cable of abrasion can increase electric leakage,
The risk of fracture causes to use electric fault.
Utility model content
The purpose of this utility model is to overcome above deficiencies, provide a kind of wear-resistant copper core polyvinyl chloride insulation and gather
Vinyl chloride jacketed cable.
The utility model provides a kind of wear-resistant copper core polyvinyl chloride-insulated polyvinyl chloride cable, including copper core, institute
It states copper core and is coated with polyvinyl chloride insulation layer, polytetrafluoroethylene (PTFE) protective layer, flame retardant coating, polyvinyl chloride sheath successively from inside to outside
With the polyvinyl chloride oversheath with several convex blocks；The cross section of the convex block is semicircle, and the convex block is according to head and the tail phase
The mode connect is arranged in the outside of the polyvinyl chloride oversheath.
Those skilled in the art can set the size and number of the convex block according to the diameter of cable, it is preferable that institute
The quantity of convex block is stated as 10-30, the radius of the semicircle convex block is 0.2-1.0mm.
Further, the polyvinyl chloride insulation layer, polytetrafluoroethylene (PTFE) protective layer, flame retardant coating and polyvinyl chloride sheath
The ratio between thickness is 1：1：1.
Further, the flame retardant coating is mica tape.
Further, the thickness of the polytetrafluoroethylene (PTFE) protective layer is 0.2-1.0mm.
Compared with prior art, what is had beneficial has the technical effect that the utility model：
1st, in external polyvinyl chloride oversheath of the cladding with convex block of polyvinyl chloride sheath, the convex block is according to head and the tail
The mode to connect is arranged in the outside of the polyvinyl chloride oversheath, and the convex block can enhance the wearability of cable；In addition,
Polyvinyl chloride sheath is added inside polyvinyl chloride oversheath, when cable is worn, even if being protected outside external polyvinyl chloride
During set failure, polyvinyl chloride sheath is also possible to prevent cable core and is destroyed, in polytetrafluoroethylene (PTFE) protective layer and polyvinyl chloride
Mica tape flame retardant coating between sheath is set, the fire resistance of cable can be improved.
2nd, polytetrafluoroethylene (PTFE) protective layer is coated in copper core, the external of polyvinyl chloride insulation layer, due to polytetrafluoroethylene (PTFE) belt
There are excellent chemical stability, corrosion resistance, self lubricity and preferable mechanical performance, polytetrafluoroethylene (PTFE) protective layer can make interior
It can between the copper core and polyvinyl chloride insulation layer in portion and the flame retardant coating of outside, polyvinyl chloride sheath and polyvinyl chloride oversheath
Preferable Relative sliding is kept, cable copper core is avoided to be pulled off and curved disconnected, extension cable physical life.
