Abstract

The utility model discloses a novel power cable, including the rubber sinle silk, be equipped with the wire casing on the rubber sinle silk, be equipped with the wire in the wire casing, the winding has around the covering on the rubber sinle silk, it has the insulating layer to wrap up on the covering, be equipped with the iron wire on the insulating layer. The wire is wrapped by the wire grooves on the rubber wire cores, so that the cable is stressed by the rubber wire cores, and meanwhile, the three iron wires are spirally wound on the insulating layer, so that the overall strength of the cable can be increased, and the cable is prevented from being broken; the aging of air to the protective sleeve can be reduced through the anti-aging film, and the service life of the cable is prolonged.

Description

Novel power cable

Technical Field

The utility model belongs to the technical field of power cable, specifically be a novel power cable.

Background

Cables are generally rope-like cables made by stranding several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a center, the entire outer surface being coated with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. The cable includes power cable, control cable, compensation cable, shielding cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like.

At present, some power cables can bear gravity when using for the cracked condition of cable appears easily in the cable, and the cable can receive the air ageing when using for a long time, influences the life of cable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel power cable to the solution makes the cracked condition of cable appear easily in the cable, and the cable can receive the air ageing when using for a long time, influences the life's of cable problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel power cable, includes the rubber sinle silk, be equipped with the wire casing on the rubber sinle silk, the wire is equipped with the wire in the wire casing, the winding has around the covering on the rubber sinle silk, can fix the wire in the wire casing around the covering, avoids appearing that the wire shifts out the wire casing and makes the unable condition of aligning the protection of rubber sinle silk, it has the insulating layer to wrap up on the covering, be equipped with the iron wire on the insulating layer.

Preferably, the quantity of iron wire is three, and is the heliciform winding on the insulating layer, can increase the bulk strength of cable through the iron wire, increase the holistic tensile resistance of cable.

Preferably, the insulating layer is made of a rubber material, and the rubber material has good insulating property, so that the conducting wire can be separated from the outside, and the condition of electric leakage is avoided.

Preferably, the insulating layer is wrapped with a waterproof layer, the waterproof layer is made of waterproof coiled material, and the waterproof coiled material has good waterproof performance and can prevent external water from permeating into the cable to cause electric leakage.

Preferably, the waterproof layer is provided with a protective sleeve, the protective sleeve is wrapped with an anti-aging film, the anti-aging film can reduce the aging of air on the protective sleeve, and the service life of the cable is prolonged.

Compared with the prior art, the beneficial effects of the utility model are that: the wire is wrapped by the wire grooves on the rubber wire cores, so that the cable is stressed by the rubber wire cores, and meanwhile, the three iron wires are spirally wound on the insulating layer, so that the overall strength of the cable can be increased, and the cable is prevented from being broken; the aging of air to the protective sleeve can be reduced through the anti-aging film, and the service life of the cable is prolonged.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1 rubber sinle silk, 2 wire casings, 3 wires, 4 around covering, 5 insulating layers, 6 iron wires, 7 waterproof layers, 8 lag, 9 ageing resistance films.

Detailed Description

Please refer to fig. 1, a novel power cable, including rubber core 1, is equipped with wire casing 2 on rubber core 1, is equipped with wire 3 in the wire casing 2, and the winding has around covering 4 on rubber core 1, can fix wire 3 in wire casing 2 around covering 4, avoids appearing that wire 3 shifts out wire casing 2 and makes the condition of rubber core 1 unable alignment protection, has insulating layer 5 around the parcel on covering 4, is equipped with iron wire 6 on insulating layer 5.

Referring to fig. 1, three iron wires 6 are spirally wound on the insulating layer 5, so that the iron wires 6 can increase the overall strength of the cable and increase the overall tensile resistance of the cable.

Referring to fig. 1, the insulating layer 5 is made of a rubber material having good insulating properties, and can separate the wires 3 from the outside to prevent electrical leakage.

Referring to fig. 1, the insulating layer 5 is wrapped with a waterproof layer 7, the waterproof layer 7 is made of waterproof coiled material, and the waterproof coiled material has good waterproof performance and can prevent external water from permeating into the cable to cause electric leakage.

Referring to fig. 1, a protective cover 8 is arranged on the waterproof layer 7, an anti-aging film 9 is wrapped on the protective cover 8, and the anti-aging film 9 can reduce the aging of air on the protective cover 8 and prolong the service life of the cable.

The working principle of the scheme is as follows: when the cable is used, the wire 3 is wrapped by the wire groove 2 on the rubber wire core 1, so that the cable bears pressure by the rubber wire core 1, and meanwhile, the three iron wires 6 are spirally wound on the insulating layer 5, so that the overall strength of the cable can be increased, and the cable is prevented from being broken; the aging of air to the protective sleeve 8 can be reduced through the anti-aging film 9, and the service life of the cable is prolonged.
