The content of the invention
Present invention aims at Halogen low-resistance combustion cross-linked polyolefin cable is provided, the cable has stronger abrasive resistance,
Conscientiously the wear problem of cable in use is solved.
The present invention is achieved through the following technical solutions：
Halogen low-resistance is fired to be set in cross-linked polyolefin cable, including cross-linked polyolefin sheath layer, cross-linked polyolefin sheath layer
There is conductor, packed layer is filled between conductor and cross-linked polyolefin sheath layer, cross-linked polyolefin sheath layer is along along its major diameter direction
The convexity layer of n bar shaped is provided with, and n meets 3≤n≤6, the n convexity layer uniform rings and protected around cross-linked polyolefin is distributed in
On the outer surface of jacket layer, and it is smooth flat at the top of the n convexity layers.
The present invention can help electricity by the way that cross-linked polyolefin sheath layer is arranged into the structure with n strip bulge layer
Cable is in use, it is to avoid by many frictionally damages, and shares friction by convexity layer, and will be set at the top of convexity layer
Smooth flat is set to, friction when convexity layer and extraneous contact can be reduced, so as to reduce damage, increases cross-linked polyolefin sheath
The durability of layer, improves the service life of cable.Other n number be not it is The more the better, inventor in practice, it has been found that with
The increase of n number, wearability gradually increases, but arrived it is a certain number of after, wearability it is increased not significantly, on the contrary with
The increase of n numbers, production technology becomes very complicated, causes production cost to improve, and is unfavorable for large-scale production.The friendship of the present invention
It can be crosslinked polyethylene restrictive coating to join polyolefin sheath layer.
Multiple rubber grains or silicon-carbide particle are provided with the top of convexity layer.It is appropriately arranged with the top of convexity layer resistance to
The particle of mill, friction when helping to increase convexity layer and extraneous contact.
It is additionally provided between cross-linked polyolefin sheath layer and packed layer in the second rubber layer, the second rubber layer filled with carbonization
Silicon grain.This set can increase appropriate intensity to cable, so as to increase wearability.
The wrapped band of stranding is additionally provided between second rubber layer and packed layer.
Rubber insulation layer is also wrapped on outside conductor.
Wear-resistant coating is additionally provided with outside the convexity layer.One layer of wear-resistant coating is set outside convexity layer, connect when with the external world
When touching wiping, first by wear-resistant coating and extraneous contact, so as to add wear-resisting timeliness, the service life of cable is extended.
The present invention compared with prior art, has the following advantages and advantages：
The present invention can help electricity by the way that cross-linked polyolefin sheath layer is arranged into the structure with n strip bulge layer
Cable is in use, it is to avoid by many frictionally damages, and shares friction by convexity layer, and will be set at the top of convexity layer
Smooth flat is set to, friction when convexity layer and extraneous contact can be reduced, so as to reduce damage, increases cross-linked polyolefin sheath
The durability of layer, improves the service life of cable.
