Description

A kind of power cable that anti-animal bites

Technical field

The utility model is related to power cable fields, and in particular to a kind of power cable that anti-animal bites.

Background technology

At this stage, most aluminium for engineering construction, state's net engineering, the upgrading of rural power grids, railway engineering, market sale close Golden polyvinyl chloride-insulated polyvinyl chloride cable all carries out insulating wrapped with common polyvinyl chloride plastics to Aluminum conductor line, It is widely adopted because simple production process, performance are qualified, price is low, but the fatal defect of this kind of cable be exactly it is not wear-resisting, Not oil resistant, not environmentally, not fire resisting, not anti-animal bites, gnaw, both it is coarse to be once applied to dark moist and contact surface for this kind of cable Place, by animal bites, gnaw destruction after, may result in entire line short, fire occur and a period of time cannot be kept normal Power supply is unfavorable for Field Force and flees from and fire-fighting and rescue, and discharges toxic gas, to live escape personnel and fire-fighting and rescue people Member causes second of injury.

Utility model content

Above-mentioned in order to solve the problems, such as, the utility model provides a kind of power cable that anti-animal bites.

The utility model is achieved through the following technical solutions：

A kind of power cable that anti-animal bites, including aluminium alloy conductor are enclosed with rubber on the outside of the aluminium alloy conductor Glue-line, close cladding rubber layer forms single-phase cable to aluminium alloy conductor outside, and single-phase cable is three and is in equilateral triangle arrangement, institute It states and is equipped with glass fiber rope filling layer on the outside of rubber layer, the wrapping layer of the glass fiber rope filling layer from inside to outside is followed successively by poly- Tacryl layer, carbon fiber wire layer, refuge floor, wearing layer.

Preferably, the thickness 1mm of the rubber layer.

Preferably, the refuge floor is worked out by mineral wool rope.

Preferably, the wearing layer forms for copper wire woven.

Preferably, the polypropylene fiber layer and carbon fiber wire layer are wire mesh structure made of left-and-right spiral winding.

Compared with prior art, the utility model has the beneficial effects that：The utility model is by being arranged polypropylene fibre Layer and carbon fiber wire layer, make the tensile property of its entire cable greatly improve, and polypropylene fiber layer and carbon fiber wire layer are equal Manufactured wire mesh structure is wound for left-and-right spiral, the tensile property of power cable is preferably ensure that in this way, it is made to use the longevity It orders longer, and is worked out by mineral wool rope by the way that refuge floor is arranged, be utilized the anti-flammability of mineral wool rope inorganic matter, resist extraneous Directly and conductive cable contacts, while mineral wool rope has certain tensile strength to open fire, is not susceptible to be broken, prevents mouse ant directly to electricity Cable damages.

Description of the drawings

Fig. 1 is the schematic diagram of structure described in the utility model.

In figure：Aluminium alloy conductor 1, rubber layer 2, glass fiber rope filling layer 3, polypropylene fiber layer 4, carbon fiber wire layer 5, Refuge floor 6, wearing layer 7.

Specific implementation mode

The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：

As shown in Figure 1, a kind of power cable that anti-animal bites, including aluminium alloy conductor 1, the aluminium alloy conductor 1 Outside is enclosed with rubber layer 2, and close cladding rubber layer 2 forms single-phase cable outside aluminium alloy conductor 1, and single-phase cable is three and is in Equilateral triangle arrangement, 2 outside of the rubber layer are equipped with glass fiber rope filling layer 3, and the glass fiber rope filling layer 3 is by introversion Outer wrapping layer is followed successively by polypropylene fiber layer 4, carbon fiber wire layer 5, refuge floor 6, wearing layer 7.

The thickness 1mm of the rubber layer 2.

The refuge floor 6 is worked out by mineral wool rope.

The wearing layer 7 forms for copper wire woven.

The polypropylene fiber layer 4 and carbon fiber wire layer 5 are wire mesh structure made of left-and-right spiral winding.

Operation principle：The utility model is related to a kind of power cables that anti-animal bites, this cable includes aluminium alloy conductor 1, rubber layer 2, glass fiber rope filling layer 3, polypropylene fiber layer 4, carbon fiber wire layer 5, refuge floor 6 and wearing layer 7, wherein rubber Glue-line 2 protects aluminium alloy conductor 1, and improves the insulating properties of cable, by the way that glass fiber rope filling layer 3 is arranged, has very Good fire-retardant and heat-blocking action；By the way that polypropylene fiber layer 4 and carbon fiber wire layer 5, polypropylene fiber layer 4 and carbon fiber wire is arranged Layer 5 all has very high tensile property, and polypropylene fiber layer 4 and carbon fiber wire layer 5 are made of left-and-right spiral winding Wire mesh structure also preferably improves the tensile property of cable in this way；It is worked out by mineral wool rope by the way that refuge floor 6 is arranged, Be utilized the anti-flammability of mineral wool rope inorganic matter, resist extraneous open fire directly and conductive cable contacts, at the same mineral wool rope have it is certain anti- Tensile strength is not susceptible to be broken, and prevents mouse ant from directly being damaged to cable, by improving cable provided with wearing layer 7 Wearability.
