Abstract

The invention discloses a dragging-resistant reinforced cable. The dragging-resistant reinforced cable comprises main cable cores, a copper tape taping layer, an inner protective sleeve and an outer protective sleeve. A cable core fixing part is arranged in the copper tape taping layer. The cross section of the cable core fixing part is a circle which is equally divided into four sectors by four insulating plates. The number of the main cable cores is four. The four main cable cores are wrapped in the four sectors of the cable core fixing part respectively in an extruded mode. The cable has good conductivity and is waterproof, insulating and resistant to oil, high temperature and oxidization, the breaking-resistant ability is high, and the cable cores are firm. Meanwhile, the shielding rate to ultraviolet light of the cable reaches 97.4 percent. The dragging-resistant reinforced cable is mainly applied to the fields of power generation, metallurgy, computers, chemical engineering, petroleum and the like.

Description

A kind of anti-reinforcement cable that pulls

Technical field

The invention belongs to field of cables, relate 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.

Summary of the invention

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

The present invention 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 coated sheath; 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 present invention has following beneficial effect in sum: 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 coated sheath 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 embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
