Description

A kind of waterproof oil resistant fire-resisting cable

Technical field

This utility model relates to technical field of electric wires and cables, a kind of waterproof oil resistant fire-resisting cable.

Background technology

At home in cable work construction, medium-low voltage power cable the most all uses direct-burried, poling or cable duct etc. buried System of laying.In work progress, the phenomenon such as often occur cable cover(ing) to abrade, to scratch is higher or the most in level of ground water The medium-low voltage power cable that rain area is laid must take waterproof measure.Power cable with cross-linked polyethylene insulation is good because of it Machinery, electric property and being easy to the performance such as are laid, non-maintaining and are widely used in power system, but this cable Epidermis is that high-molecular organic material is polymerized, and does not have metallic character, is particularly easy to cause epidermis under by External Force Acting The damage of macromolecular material so that cable is the most easily making moist, cause the performance of cable to significantly reduce, shadow Ring service life.

Utility model content

The purpose of this utility model is, for the deficiencies in the prior art, it is provided that a kind of waterproof oil resistant fire-resisting cable, cable Compact conformation, has a radial direction longitudinal water-blocking oil-resistant effect of excellence, and mechanical strength scratch resistance high, wear-resisting, cold-resistant, insulation electrical Property is good.

For achieving the above object, technical scheme provided by the utility model is:

A kind of waterproof oil resistant fire-resisting cable, including Stranded cable core and be located at the clad outside Stranded cable core, described Clad includes that pretension cladding is arranged the most successively the first water blocking layer, flame retardant coating, armor and oil resistant crosslinked with silicane are poly- Ethylene restrictive coating, the first described water blocking layer is for being disposed with semiconductive PVC layer, lead thin layer, layers of reinforcement from the inside to the outside Laminated thin. g., lead tape, per share cable core is disposed with the copper conductor of surface-coated polyurethane water-proof coating, nanometer from the inside to the outside Flame retardant insulation, the second water blocking layer, ceramic fibre fire resistant belt and fluororubber layer, hole inside described cable core, cable core with Being provided with implant between clad, it is poly-that the outside of described oil resistant organosilane crosslinked polyethylene restrictive coating is provided with welding corrugated aluminium set Pvdf layer.

Preferably, described Stranded cable core is three strands of cable core close-packed arrays triangular shape each other.

Preferably, the second described water blocking layer is lead-semiconductive polyethylene composite band waterproof layer.

Preferably, described implant is swelling fiber or the water blocking yarn of blocking water.

Preferably, described flame retardant coating is refractory synthetic mica tape or glass fiber rope.

Compared with prior art, the beneficial effects of the utility model are:

The waterproof oil resistant fire-resisting cable that this utility model provides, in cable core outside, pretension arranges clad, sets simultaneously Put multilayer flashing structure, oil resistant structure, fire resistant flame retardant structure etc., make the construction of cable compact, complimentary to one another between each functional layer, have Effect stops the diffusion to cable such as oils, moisture, has the radial direction longitudinal water-blocking oil-resistant effect of excellence, and mechanical strength Scratch resistance high, wear-resisting, cold-resistant, insulation electrical is good, effectively extends the service life of cable, and the maintenance reducing cable becomes This.

Below in conjunction with the accompanying drawings with embodiment, the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Detailed description of the invention

In conjunction with Fig. 1, the waterproof oil resistant fire-resisting cable that the present embodiment provides, including Stranded cable core 1 and be located at Stranded cable Clad 2 outside core, clad includes the first water blocking layer 3 of pretension cladding setting, flame retardant coating 4, armor 5 the most successively And it being coated on the oil resistant organosilane crosslinked polyethylene restrictive coating 6 of armor outside, the first water blocking layer 3 is for set gradually from the inside to the outside The laminated thin. g., lead tape of semiconductive PVC layer 31, lead thin layer 32, layers of reinforcement 33, per share cable core 1 is had to set gradually from the inside to the outside There are the copper conductor 11 of surface-coated polyurethane water-proof coating, nano flame retardant insulating barrier the 12, second water blocking layer 13, ceramic fibre fire-resistant Band 14 and fluororubber layer 15, be provided with implant 8 between hole, cable core and clad inside cable core, oil resistant crosslinked with silicane gathers The outside of ethylene restrictive coating 6 is provided with welding corrugated aluminium set polyethylene layer 7.Preferably, wherein, Stranded cable core is three strands of cables Core close-packed arrays triangular shape each other；Second water blocking layer is lead-semiconductive polyethylene composite band waterproof layer；Implant is for blocking water Swelling fiber or water blocking yarn；Flame retardant coating is refractory synthetic mica tape or glass fiber rope.

The waterproof oil resistant fire-resisting cable that the present embodiment provides arranges clad at cable core outside pretension, arranges many simultaneously Layer waterproof construction, oil resistant structure, fire resistant flame retardant structure etc., make the construction of cable compact, complimentary to one another between each functional layer, effectively hinders The only diffusion to cable such as oils, moisture, has the radial direction longitudinal water-blocking oil-resistant effect of excellence, has mechanical strength simultaneously Scratch resistance high, wear-resisting, cold-resistant, insulation electrical, etc. characteristic, effectively extend the service life of cable, reduce the maintenance of cable Cost, is particluarly suitable under humidity, dark industrial production environment making as laid in tunnel, pipeline, soil or the place having water With, waterproof, moistureproof, oil resistant, refractory ability are strong.

The announcement of book and teaching according to the above description, this utility model those skilled in the art can also be to above-mentioned reality The mode of executing changes and revises.Therefore, this utility model is not limited to detailed description of the invention disclosed and described above, right Modifications and changes more of the present utility model should also be as falling in scope of the claims of the present utility model.
