Abstract

The utility model discloses a fire resisting cable who easily separates sinle silk, including three magnesium aluminum alloy conductor, every magnesium aluminum alloy conductor outward in proper order the cladding have around the covering in the poly (aryl ether ketone) ribbon, the polysulfone (PSO) insulating layer constitutes insulation core, three insulation core respectively through extrusion molding in three cross -section is sectorial EP rubbers bearer layer, every two adjacent sectorial EP rubbers bearer layer intersection line ends are equipped with one and tear the rope, tear the rope submergence in two sectorial EP rubbers bearer layers, the poly (aryl ether ketone) ribbon that the outer cladding in proper order of EP rubbers bearer layer has the high temperature resistant erosive power of resistant the environment is outward around the covering, low carbon polymer fire resistance and insulation oversheath layer. The utility model discloses an in that distribute three insulation core in the low cigarette flame -retardant ethylene -propylene rubber bearer layer of three independent thermoplasticity environment friendly non halogen and the rope is torn in the cooperation, no matter retrieve still to connect the installation, all conveniently separate its insulating layer to peel off out the copper conductor, the cable has good high temperature resistant, fire -resistant, fire behaviour in addition.

Description

A kind of fire-resisting cable being easily isolated core

Technical field：

The utility model is related to fire-resisting cable, more particularly, to a kind of fire-resisting cable being easily isolated core.

Background technology：

Cable adopts copper as conductor mostly, and copper conductor cost accounts for cable raw material totle drilling cost more than 90%, the one-tenth of copper conductor This is of a relatively high, and discarded cable typically can be reclaimed copper conductor, and the braiding layer outside original conductor is all to be woven into cylinder mesh Shape structure, manual removal is difficult；Additionally, cable needs to be attached equipment, the outer layer of cable surface during mounting and installation Generally require and scratched with knife, operation is fairly cumbersome also to carry certain danger.

Utility model content：

In order to make up prior art problem, the purpose of this utility model is to provide a kind of flame proof electrical being easily isolated core Cable, either reclaims or connects and install, and all convenient separation to its insulating barrier, thus separate copper conductor.

The technical solution of the utility model is as follows：

Be easily isolated the fire-resisting cable of core it is characterised in that：Including three magnadure conductors, every magnadure is led It is coated with lapping layer in the PAEK band of high temperature resistant resistance to environmental attack ability in vitro successively, polysulfones insulating barrier constitutes insulated wire Core, three insulated wire cores respectively through extrusion moulding in three sections be fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers In bearing bed, often two neighboring fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers bearing bed intersecting lens end is provided with one Root tear rope, tear rope is immersed in two fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers bearing beds, thermoplasticity It is coated with the PAEK band of high temperature resistant resistance to environmental attack ability successively outside environment friendly non-halogen low-smoke and flame retardant EP rubbers bearing bed Outer lapping layer, low-carbon (LC) macromolecule hot-face insulation external sheath layer.

The described fire-resisting cable being easily isolated core it is characterised in that：Described insulated wire cores external spiral is wound with rock Cotton cord, spiral winding spacing is generally 1.2 ~ 3.5mm, is also wrapped on oxygen barrier layer outside the insulated wire cores being wound around mineral wool rope.

The utility model has the advantages that：

The utility model novel in structural design, by being distributed in three independent thermoplastic environment-protectings by three insulated wire cores In LSOH anti-flaming EP rubbers bearing bed and coordinate tear rope, either reclaim or connect and install, all convenient exhausted to it The separation of edge layer, thus separating copper conductor, this outer cable has excellent high temperature resistant, fire resisting, fire resistance.

Brief description：

Fig. 1 is structural representation of the present utility model.

Specific embodiment：

Referring to accompanying drawing：

It is easily isolated the fire-resisting cable of core, including three magnadure conductors 1, every magnadure conductor 1 is outer successively It is coated with lapping layer 2 in the PAEK band of high temperature resistant resistance to environmental attack ability, polysulfones insulating barrier 3 constitutes insulated wire cores, three Root insulated wire cores are that fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers carries through extrusion moulding in three sections respectively In layer 4, often two neighboring fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers bearing bed 4 intersecting lens end is provided with one Tear rope 5, tear rope 5 is immersed in two fan-shaped thermoplastic environment-protecting LSOH anti-flaming EP rubbers bearing beds 4, thermoplasticity The outer PAEK band being coated with high temperature resistant resistance to environmental attack ability successively of environment friendly non-halogen low-smoke and flame retardant EP rubbers bearing bed 4 Outer lapping layer 6, low-carbon (LC) macromolecule hot-face insulation external sheath layer 7.

Insulated wire cores external spiral is wound with mineral wool rope 8, and spiral winding spacing is generally 1.2 ~ 3.5mm, is wound around mineral wool rope 8 It is also wrapped on oxygen barrier layer 9 outside insulated wire cores.
