Abstract

The utility model discloses a multifunctional power cable, wherein, a cable core of the multifunctional power cable comprises a plurality of wire cores that are intertwisted together; waterproof flame-retardant filler yarns are filled between the wire cores, and a high fire-retardant halogen-free low-smoke glue spreading fabric tape is arranged outside the wire cores in a winding coating manner, so as to form the cable core; water blocking polymer fillers are additionally arranged at the middle parts of conductive bodies, and the outer parts of the conductive bodies are coated with waterproof belts and fire-proof mica tapes sequentially in a winding manner and then are coated with low-smoke halogen-free fire-proof environment-friendly insulation layers in an extruded manner, so that the wire cores are formed; and a high fire-retardant inside liner, an armor layer, an erosion resistant coating, the high fire-retardant halogen-free low-smoke glue spreading fabric tape and an outer sheath are arranged at the outer part of the cable core. In the multifunctional power cable, the water blocking polymer fillers are arranged between copper conductive bodies, the conductive bodies are coated with the mica tapes in a winding manner, and then the low-smoke halogen-free fire-proof insulation layers are arranged in an extruded manner, so that the insulated wire cores are formed; in addition, fire-proof flame-retardant filler yarns are filled between the stranded insulated wire cores and then the high fire-retardant glue spreading fabric tape is utilized to form a whole body. The multifunctional power cable can achieve water resistance, fire resistance, flame retardancy, corrosion prevention and impact resistance, and the service life and the safety of the cable can be improved through a physical method. The safe operation of the power cable can be better ensured.

Description

A kind of multifunction power cable

Technical field

The utility model relates to a kind of multi-functional cable, specifically be a kind of have block water, the multifunction power cable of fire-resistant, Corrosion Protection.

Background technology

At present, there are being personnel to assemble numerous sealing places, for example: underground railway, skyscraper, movie theatre, market, naval vessel etc., and for the place of installing than expensive device, for example; Computer floor, various electrical apparatus control systems, telephone exchange unit room etc. adopt as the special cable of fire-retardant, low smoke and zero halogen type or low toxicity according to different needs.The special cable of domestic production now is not because the restriction of manufacturing process and cable material has a kind of combination property that multiple function is integrated in one than higher cable.In order better to avoid personnel's injures and deaths, the heavy losses of property, the exploitation of environmental protection low smoke, zero halogen, low toxicity, fire-resistant serial electric wire has become a much-talked-about topic in cables manufacturing field in the world.

The utility model content

The purpose of this utility model provides a kind of multi-functional rolling into one, can waterproof, fire prevention, again withstand corrosion, reduce and pollute, also have the multifunction power cable of anti-collision simultaneously.

A kind of multifunction power cable described in the utility model, it comprises the cable core that is positioned at cable center, described cable core comprises some cores that are intertwined, and fills the fire-resistant waterproof gasket for packing between core, and wrapped high flame retardant low smoke, zero halogen gluing strap is formed cable core outside core; Described core is to add the water-proofing powder filler in the middle of conductor, and the wrapped successively outward water blocking tape of conductor, fire-resistant isinglass belt extrude low smoke and zero halogen environmental protection refractory insulating layer again and form; Wrapped high flame retardant inner covering is provided with armour outside the high flame retardant inner covering outside cable core, anticorrosive coating outside armour again, and wrapped high flame resistance, low smoke Halogen gluing strap outside anticorrosive coat, outermost layer is provided with the low-smoke non-halogen flame-retardant oversheath.Above-mentioned anticorrosive coat is soft pitch anticorrosive coat.

Main innovation of the present utility model is that the water-proofing powder filler is arranged between copper conductor, wrapped more outward water blocking tape of conductor and fire-resistant isinglass belt, extrude the low smoke and zero halogen refractory insulating layer then and form insulated wire cores, be filled with the flame-retardant gasket for packing between the stranding insulated wire cores and use high flame retardant gluing strap stranding.Armour is coated with the fluxed bitumen anticorrosive coat, the external low-smoke halogen-free flame-retardant sheath layer that is provided with of cable.This cable can waterproof, fire-resistant, fire-retardant, anticorrosion, and anti-collision, and with the method for physics, the useful life and the fail safe that have improved cable.More can guarantee the safe operation of electric wire.

Description of drawings

Fig. 1 is the cross-sectional structure schematic diagram of a kind of embodiment of the utility model.

Embodiment

Below in conjunction with drawings and Examples, further specify the utility model.

With reference to Fig. 1, multifunction power cable of the present utility model, agent structure comprises core, this core inside is copper conductor 1, add water-proofing powder filler 2 in the middle of the conductor, conductor is surrounded with waterstop 3 and fire-resistant isinglass belt 4 outward, extrudes low smoke and zero halogen environmental protection refractory insulating layer 5 again and forms insulated wire cores.Behind some such insulated wire cores strandings, add fire-resistant waterproof gasket for packing 6 in the core gap, wrapped again high flame retardant low smoke, zero halogen gluing strap 7 is formed cable core, wrapped high flame retardant inner covering 8 outside cable core, outside inner covering, be provided with armour 9, dress armour galvanized steel strip or steel wire; Outside armour, apply soft pitch anticorrosive coat 10 again, at the external wrapped one deck high flame resistance, low smoke Halogen gluing strap 11 of anticorrosive coat, outside high flame retardant low smoke, zero halogen gluing strap 11, be provided with low-smoke non-halogen flame-retardant oversheath 12.

Above-mentioned cable can be that single core also can be a multicore.

The utility model provides a kind of thinking and implementation method of multifunction power cable; concrete application approach is a lot; for those skilled in the art; do not breaking away under the principle of the present utility model; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
