The utility model discloses a low-smoke zero-halogen flame-retardant termite-proof control cable, and overcomes the defects of the conventional control cable that the high-temperature resistant performance is poor, poisonous smog is released during burning, the luminousness is low, and the termite-proof performance is poor. The utility model has the advantages of environmental protection, flame-retardant performance, simple structure, convenient use, and the like, and can effectively improve the weatherability and the anti-interference ability of the control cable. The control cable provided by the utility model adopts a multi-core structure; the structure comprises a plurality of conductors arranged in an infill body; a double-layered cable alloplastic shielding layer and a low-smoke zero-halogen flame-retardant termite-proof sheathing layer are coated on the outer wall of the infill body; and a low-smoke zero-halogen flame-retardant irradiation insulation layer is also arranged on the outer wall of each conductor.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to the termite-proof control cable of a kind of low-smoke non-halogen flame-retardant.
Background technology
Increase year by year by the electric fire that causes in recent years, and the fire that is wherein caused owing to the electric wire reason accounts for sizable ratio, causes enormous economic loss to society.Therefore there are a large amount of electric equipments and the intensive place of laying a large amount of cables to adopt flame retardant cable to stop fire spreading in power plant, transformer station etc., adopt fire-resisting cable to guarantee that the uninterrupted power supply in important loop seems and become more and more important.
Same termite also is subjected to people's attention day by day for the harm of cable.Because the life habit of termite, hazard approach is comparatively special, and cable is laid in underground again for a long time, and termite damage is hidden, therefore generally is difficult for discovering and getting rid of before killed.In case find, promptly played fault or caused the accident, and check after killed and maintenance very difficult again, cause economic loss, so plastic cable uses with burying, prevent termite is very important.The termite-proof branch that chemical method and physical method are arranged of cable.Chemical method is to add pesticide in cable jacket material, principal item has Niran, dieldrite, drinox, heptachlor etc., the long-term proof of using has good anti-ant effect, but, owing to poison health in the volatilization of being heated of sheath extrusion process Chinese traditional medicine, cable use the age long afterwards medicine can from sheath, move, soil and water source are polluted.So-called " physics is prevented the ant method " mainly is to utilize the hardness of plastics and the smoothness of cable surface to reach the purpose that prevents termite attack, but not utilizes the insecticidal action of chemical substance.Studies have shown that according to the bite hardness limit of thing of termite, general available shore hardness is as criterion.When material hardness during less than Shao Shi D70 termite can sting movingly, and if hardness greater than D70, body surface is smooth, the termite end opening of then having no way of; But being cable laying, the English walnut of high rigidity bring difficulty and material can not satisfy environmental requirement.
The utility model content
The purpose of this utility model is exactly shortcomings such as the control cable resistance to elevated temperatures is poor, burning discharges toxic smog, light transmittance is low, termite-proof poor performance in order to solve; A kind of termite-proof control cable of low-smoke non-halogen flame-retardant with advantages such as environmental protection, fire-retardant, termite-proof, simple in structure, easy to use, the weatherability that can effectively improve control cable and antijamming capabilities is provided.
For achieving the above object, the utility model adopts following technical scheme:
The termite-proof control cable of a kind of low-smoke non-halogen flame-retardant, it comprises that many conductors place in the obturator, the double-deck heterogeneous screen of outer wall parcel cable and the termite-proof restrictive coating of low-smoke non-halogen flame-retardant of described obturator; Outer wall at every conductor also is provided with low-smoke non-halogen flame-retardant irradiation insulating barrier simultaneously.
Also be provided with inner covering and armour between double-deck heterogeneous screen of described cable and the termite-proof restrictive coating of low-smoke non-halogen flame-retardant.
The double-deck heterogeneous screen of described cable is internal layer lapped shielding layer and outer braid screen; Wherein, the internal layer lapped shielding layer is a compound copper-plastics band, and the outer braid screen is copper wire or tinned copper wire or aluminium in copper magnesium braid over braid.
Described obturator is a halogen-free low-smoke flame retardant material.
The termite-proof restrictive coating of described low-smoke non-halogen flame-retardant is anti-90 ℃ of low-smoke and halogen-free flame retardant polyolefin jackets.
The termite-proof control cable of low-smoke non-halogen flame-retardant of the present utility model comprises many conductors, and conductor places in the obturator, the double-deck heterogeneous screen of outer wall parcel cable and the termite-proof restrictive coating of low-smoke non-halogen flame-retardant of obturator; Outer wall at every conductor also is provided with low-smoke non-halogen flame-retardant irradiation insulating barrier simultaneously.Conductor should be an annealed copper wire, can be that single copper cash also can be a stranded conductor.
Cable insulation material is selected 150 ℃ of environment-friendly type irradiation crosslinking halogen-free low-smoke and flame retardant Insulation Material for use, and this Insulation Material had both guaranteed that product has resistance to elevated temperatures, good electric property and mechanical performance, had guaranteed the environmental-protecting performance of product again.
Its screen of cable adopts double layer screen, that is: the compound copper-plastics band shielding adds copper wire or tinned copper wire or aluminium in copper magnesium braid shielded.Double layer screen has changed the individual layer copper wire braid shielded of control cable in the past, and the antijamming capability to external world that the shielding of double-deck different materials has strengthened cable has also increased the mechanical performance of cable, uses drainage thread to make shield effectiveness more reliable.The wrapped shielding of compound copper-plastics band contains and moulds the band mechanical stress promptly by the shielding properties of copper strips, makes screen firm more, reliable; Tinned copper wire braiding makes the screen of cable have corrosion-resistant, oxidation resistant characteristic, in the useful life of the cable shield of increase, makes the performance shielding action that screen more can be permanent.
Cable then should have inner covering under the armour as adopting the metal armouring layer, and inner covering can be for extruding or wrapped, and material therefor is the low-smoke non-halogen flame-retardant environment-friendly materials.
Cable cover(ing) adopts termite-proof 90 ℃ of low-smoke and halogen-free flame retardant polyolefin jacket materials.Characteristics such as protective cover material has that anti-cracking performance is excellent, thermal contraction is little, easy processing, taste are little, LSOH anti-flaming the most important thing is effectively to prevent the termite destruction that bites.
The beneficial effects of the utility model are: environmental protection, and termite-proof; Simple in structure, easy to use, antijamming capability is strong, good weatherability, and working stability is reliable.
