Abstract

The utility model relates to a high-efficiency, energy-saving and environment-friendly halogen-free low-smoke highly flame-retardant cable for the distribution, transmission and power connection of an electrical circuit. The cable comprises at least three conductor cores; wherein, an insulating thermoplastic crosslinked polyolefin layer is extruded around each conductor core from the inside to outside to form a cord; the three cords are wrapped together in a wrapping glass fiber band; asbestos filler is filled in the gap between the insulating thermoplastic crosslinked polyolefin layers and the wrapping glass fiber band; and a flame-retardant polyolefin sheath is arranged outside the wrapping glass fiber band. After the utility model adopts the technical scheme, since the sheath adopts low-smoke halogen-free flame-retardant polyolefin sheath material, the flame-retardant property of the cable is greatly improved, the escaped amount of smoke and halogen is reduced, and the asbestos adopted as the filler and the wrapping glass fiber band not only is environment-friendly but also can improve the flame-retardant property.

Description

Highly effective energy-conserving environmental-protecting type low smoke, zero halogen high flame-retardant cable

Technical field:

The utility model relates to cable, specifically is meant the highly effective energy-conserving environmental-protecting type low smoke, zero halogen high flame-retardant cable that a kind of electric wiring distribution transmits electric power and connects.

Background technology:

At present along with all trades and professions automaticity is to improve, the former used plain edition cable of transferring electric power that is used as can not satisfy present requirement, the general Halogen of plain edition cable, fire resistance are relatively poor, have a large amount of cigarettes and halogen to overflow during burning, and power transmission efficiency is relatively poor, and environment is polluted.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, and a kind of highly effective energy-conserving environmental-protecting type low smoke, zero halogen high flame-retardant cable with advantages such as Halogen, low cigarette, high flame retardants is provided.

The technical scheme that provides of the utility model is for achieving the above object: highly effective energy-conserving environmental-protecting type low smoke, zero halogen high flame-retardant cable, include at least three wire stylets, extrude cross-linked polyolefin thermoplastics type insulating barrier from inside to outside and form stranding around each wire stylet, three strandings are wrapped in the glass twining package tape jointly, gap between cross-linked polyolefin thermoplastics type insulating barrier and glass twining package tape is provided with the asbestos filler, and the polyolefin fire retardant jacket is established in the outside of glass twining package tape.

After the utility model adopted technique scheme, sheath adopted low-smoke and halogen-free flame retardant polyolefin jacket material, had greatly improved the flame-retarding characteristic of cable, reduced the escaped quantity of smog and halogen; Adopt asbestos as inserts and glass twining package tape, not only environmental protection, and can improve flame-retarding characteristic.

Description of drawings:

Fig. 1 is a cross section structure schematic diagram of the present utility model.

Embodiment:

See shown in Figure 1, this preferred embodiment includes three wire stylets 1, extrude cross-linked polyolefin thermoplastics type insulating barrier 2 from inside to outside and form stranding around each wire stylet, three strandings are wrapped in the glass twining package tape 3 jointly, the gap that cross-linked polyolefin thermoplastics type insulating barrier 2 and glass twining package tape are 3 is provided with asbestos filler 5, and polyolefin fire retardant jacket 4 is established in the outside of glass twining package tape 3.The polyolefin of present embodiment all adopts polyethylene.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.

Claims

1, highly effective energy-conserving environmental-protecting type low smoke, zero halogen high flame-retardant cable, include at least three wire stylets (1), it is characterized in that: extrude cross-linked polyolefin thermoplastics type insulating barrier (2) from inside to outside and form stranding around each wire stylet, three strandings are wrapped in the glass twining package tape (3) jointly, gap between cross-linked polyolefin thermoplastics type insulating barrier (2) and glass twining package tape (3) is provided with asbestos filler (5), and polyolefin fire retardant jacket (4) is established in the outside of glass twining package tape (3).
