Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a polyolefin sheathed cable. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, used to connect circuits, electrical appliances, etc.; however, since the sheath on the outer periphery of the cable is made of rubber, it is very easy to be damaged when scratched, and the copper wire inside is also easily scratched, which makes it less safe. To this end, we propose a polyolefin sheathed cable. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a polyolefin sheathed cable.

[0005] The outer periphery of the silicone ring tube is sleeved with a nylon cloth layer for protection, and the outer periphery of the nylon cloth layer is covered with a stab-proof cloth layer for protection, and the outer periphery of the stab-proof cloth layer is sleeved with a polyolefin sheath layer for protection.

[0006] By adopting the above technical solution, when the cable is used, the nylon cloth layer and the stab-proof cloth layer arranged on the outer periphery of the cable body can cooperate with each other, so as to improve the strength of the cable body, so that it is not easy to be directly damaged when scratched, and improve the safety of the copper wire inside the cable line, and at the same time cooperate with the polyolefin sheath layer, so as to effectively improve the safety of the cable body;

[0007] When the cable is in use, since the silicone ring tube has a certain resilience and multiple cavities arranged on its inner side, the buffering performance of the silicone ring tube is improved, so that when the cable body is squeezed, the copper wire inside will not be damaged. At the same time, the upper casing layer and the spacer layer are combined to improve the safety of the copper wire and the strength of the cable.

[0008] Specifically, a support layer for improving strength is installed on the outer periphery of the casing layer.

[0009] By adopting the above technical solution, the design of the support layer facilitates improving the strength of the casing layer, so that the bending resistance of the cable body is improved.

[0010] Specifically, the outer periphery of the sleeve layer is equipped with a flame retardant layer located between the sleeve layer and the support layer.

[0011] By adopting the above technical solution and the design of the flame retardant layer, it is convenient to improve the fire resistance of the cable body.

[0012] Specifically, the outer periphery of the support layer is coated with a corrosion-resistant layer for protection.

[0013] By adopting the above technical solution, the design of the corrosion-resistant layer facilitates improving the service life of the cable body.

[0014] Specifically, the plurality of groups of cavities are evenly distributed inside the silicone ring tube.

[0015] By adopting the above technical solution, the inner side of the silicone ring tube presents evenly distributed cavities, so that when the silicone ring tube is subjected to impact forces from all directions, it can buffer the impact forces, thereby facilitating the protection of the cable body.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the cable body, nylon cloth layer, stab-proof cloth layer and polyolefin sheath layer. When the cable is in use, the nylon cloth layer and stab-proof cloth layer arranged on the outer periphery of the cable body can cooperate with each other, so as to improve the strength of the cable body, make it less likely to be directly damaged when scratched, and improve the safety of the copper wire inside the cable. At the same time, the polyolefin sheath layer is combined to effectively improve the safety of the cable body.

[0018] 2. The technical solution of the present application, through the design of the casing layer, the spacer layer, the silicone ring tube and the cavity, when the cable is in use, because the silicone ring tube has a certain resilience and the multiple groups of cavities arranged on the inner side thereof, it is convenient to improve the buffering performance of the silicone ring tube, so that when the cable body is squeezed, the copper wire inside it will not be damaged. At the same time, with the casing layer and the spacer layer, it is convenient to improve the safety of the copper wire and at the same time improve the strength of the cable.
