Abstract

The utility model discloses a silicon rubber insulated thermoplastic sheathed cable which consists of anaerobic copper wires, insulators, a filler, a waterproof taped covering, a fireproof taped covering and a sheath. A plurality of strands of anaerobic copper wire are twisted into copper wire groups, the insulated cores are formed by extruding the insulators outside the copper wire groups, a plurality of insulated cores are twisted to form a cable core, and the filler is extruded outside the cable core; and the waterproof taped covering and the fireproof taped covering are extruded outside the filler in sequence and the sheath is extruded outside the fireproof taped covering. The silicon rubber insulated thermoplastic sheath cable is stable in structure, light in weight and small in external diameter, and has the advantages of avoiding continued ignition after being fired, and achieving draining property, no halogen, low smoke, no toxicity and no corrosion.

Description

A kind of silicon rubber insulation thermoplastic sheath cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of silicon rubber insulation thermoplastic sheath cable.

Background technology

At present, indoor the crowd is dense, the important place electric line cable of space-closed in some skyscrapers, market, megastore, public place of entertainment, large stadium, hospital of school etc.Because the importance in its place, fail safe, so to the quality requirement of cable, configuration requirement will be high, in case breaking out of fire will cause life, the loss of property, consequence is hardly imaginable.

The utility model content

In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind ofly to be had the water proofing property fire prevention and not to prolong combustion, the silicon rubber insulation thermoplastic sheath cable of Halogen, low cigarette, nontoxic free from corrosion advantage.

The utility model takes following technical scheme to realize: a kind of silicon rubber insulation thermoplastic sheath cable is comprised of copper free wire, insulator, gasket for packing, the lapping layer that blocks water, fire prevention lapping layer and sheath, described copper free wire strands becomes the copper wire group, described copper wire group is extruded with described insulator outward and consists of insulated wire cores, the edge cores that thoroughly do away with are twisted into cable core more, outside cable core, be extruded with described gasket for packing, described gasket for packing is extruded with described lapping layer and the described fire prevention lapping layer of blocking water outward successively, and described fire prevention lapping layer is extruded with described sheath outward.

Described insulator adopts the import silastic material to make.

Described sheath adopts low smoke, zero halogen polylefin thermoplatic material to make.

The utlity model has in sum following beneficial effect:

1, Stability Analysis of Structures, lightweight, external diameter is little;

2, discharging water property, fire line is caught fire and is not prolonged combustion, Halogen, low cigarette, nontoxic without corrosion.

Description of drawings

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, copper free wire; 2, insulator; 3, gasket for packing; 4, the lapping layer that blocks water; 5, fire prevention lapping layer; 6, sheath.

Embodiment

As shown in Figure 1, a kind of silicon rubber insulation thermoplastic sheath cable is comprised of copper free wire 1, insulator 2, gasket for packing 3, the lapping layer 4 that blocks water, fire prevention lapping layer 5 and sheath 6, described copper free wire 1 strands becomes the copper wire group, described copper wire group is extruded with described insulator 2 outward and consists of insulated wire cores, the edge cores that thoroughly do away with are twisted into cable core more, outside cable core, be extruded with described gasket for packing 3, be extruded with successively described lapping layer 4 and the described fire prevention lapping layer 5 of blocking water outside the described gasket for packing 3, be extruded with described sheath 6 outside the described fire prevention lapping layer 5.

The utility model is such implementation: insulator 2 adopts the import silastic material to make, and sheath 6 adopts low smoke, zero halogen polylefin thermoplatic material to make.

It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
