Abstract

The utility model discloses an anti-dragging reinforcing cable, comprising a main line core, a copper strip coating layer, an inner protective sleeve and an external sleeve. The internal part of the copper strip coating layer is provided with a line core fixing member, and the cross section of the line core fixing member is a circle evenly divided into four sectors by four insulation plates. The main line core has four groups, which are respectively disposed in the four sectors of the line core fixing member. The anti-dragging reinforcing cable is advantageous in that the cable is good in conductive performance, water and oil resistance, and broken line resistance; the line core is stable, and is mainly applied in fields like power generation, metallurgy, computer, chemical petroleum and others; the cable is capable of insulation and resisting high temperature and oxidation resistance; the shielding rate of ultraviolet ray reaches to 97.4%.

Description

A kind of anti-reinforcement cable that pulls

Technical field

The utility model belongs to field of cables, relates in particular to a kind of anti-reinforcement cable that pulls.

Background technology

At present, along with developing rapidly of Chinese national economy and improving constantly of living standards of the people, accelerate the growth of cable consumption, the quality requirement of cable has also constantly been improved.But the material that traditional cable adopts and structure, along with the cable growth of running time, resist and pull poor performance, and core is insecure, is easy to produce the phenomenons such as shedding, core fracture, moisture intrusion.Only meet the requirements, just can better ensure the production and application of cable.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide one, and to possess core firm, high temperature resistant waterproof, anti-pulling and the anti-reinforcement cable that pulls of the advantage such as antiultraviolet.

The utility model takes following technical scheme to realize: a kind of anti-reinforcement cable that pulls; it comprises master core, copper strips belting layer, internal protective cover and outer jointing jacket; described copper strips belting layer inside is provided with core fixture; described core fixture cross section be a circle by four bar insulation plates be divided into four fan-shaped; described master core is four groups, is extruded in respectively four fan-shaped inside of described core fixture.

Described master core is made up of nickel plating aluminium wire center conductor and the skinning cortex, the fluorubber insulating barrier that are wrapped in nickel plating aluminium wire center conductor outside, aluminium wire heater wire of described fluorubber insulating barrier internal package.

Described internal protective cover is made up of the urethane crosslinks annealed wire mesh grid of adding ultraviolet screener.

Described outer jointing jacket is the low-smoke halogen-free polyolefin material that adds anti-ointment, organosilicon and antioxidant.

The utlity model has in sum following beneficial effect: this kind of cable conduction performance is good, waterproof oil resistant, anti-broken string ability is strong, core is firm, is mainly used in the fields such as generating, metallurgy, computer, chemical petroleum, insulation high-temperature-resistant, anti-oxidant, meanwhile, also there is stronger ability and ultraviolet resistance, ultraviolet shielding rate has been reached to 97.4%.

Embodiment

As illustrated in fig. 1 and 2; a kind of anti-reinforcement cable that pulls; it comprises master core 1, copper strips belting layer 3, internal protective cover 5 and outer jointing jacket 6; described copper strips belting layer 3 inside are provided with core fixture 2; described core fixture 2 cross sections are circles by four bar insulation plates be divided into four fan-shaped; described master core 1 is four groups, is extruded in respectively four fan-shaped inside of described core fixture 2.

Described master core 1 is made up of nickel plating aluminium wire center conductor and the skinning cortex, the fluorubber insulating barrier that are wrapped in nickel plating aluminium wire center conductor outside, aluminium wire heater wire of described fluorubber insulating barrier internal package.

Described internal protective cover 5 is made up of the urethane crosslinks annealed wire mesh grid of adding ultraviolet screener.

Described outer jointing jacket 6 is the low-smoke halogen-free polyolefin materials that add anti-ointment, organosilicon and antioxidant.

This cable has reached 97.4% to ultraviolet shielding rate; The permission bending radius of this cable is the outside diameter of cable 10 times; The permission reversed bending of this cable 6,500,000 times.

The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
