Technical field:
The utility model relates to the special cable field, specifically is a kind of uvioresistant, the anti-bird pest plateau of protection against rodents special cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
Structure for the plateau special cable: in copper conductor, insulating barrier, restrictive coating etc. are arranged.Such cable of tradition is because insulating barrier and restrictive coating adopt is silastic material, so performances such as the strength of materials, low smoke and zero halogen, antiultraviolet can not satisfy above-mentioned requirements.
At present, along with the reinforcement of science and technology development and environmental protection concept, the material that forces cable factory's commercialization to meet specific (special) requirements such as environmental protection replaces traditional material, makes environment-friendly cable or what is called " cleaning cable ".The plateau cable is to the particularity that cable uses, and needs cable to have characteristics such as cold-resistant, UV resistant, fire-retardant, protection against rodents, anti-bird pest, low cigarette, smokeless, softness, guarantees the fail safe of using.But the material that uses is difficult to satisfy fully simultaneously above-mentioned requirements at present.The utility model can satisfy the natural conditions of highlands, solves the above problems.
The utility model content:
The utility model purpose provides the anti-bird pest plateau of a kind of uvioresistant, protection against rodents special cable, has characteristics such as cold-resistant, UV resistant, uprising wind and snow, protection against rodents, anti-bird pest, environmental protection, solves traditional cable and can not adapt to the special natural conditions in highlands.
Technical scheme of the present utility model is as follows:
A kind of uvioresistant, the anti-bird pest plateau of protection against rodents special cable, comprise several conductors, insulating barrier, it is characterized in that: described conductor is by many stranded the forming of copper wire, the conductor outside extrudes the halogen-free flame retarding elastomer insulating barrier, the conductor of many wrap insulate layers is twisted into cable core, described several conductor wherein three be the quadrant cylindrical conductor, one is cylindrical conductor, side clearance is provided with the column gasket for packing in the conductor of described several wrap insulate layers, and the outside is enclosed with inner restrictive coating, armour, external sheath layer successively.
Described uvioresistant, the anti-bird pest plateau of protection against rodents special cable, it is characterized in that: described inner restrictive coating and external sheath layer all adopt Halogen antiultraviolet, protection against rodents fire retardant polyolefin material, and described armour adopts double-layer wire and internal layer dextrad to constitute.
The anti-bird pest plateau of described uvioresistant, protection against rodents special cable is characterized in that: described conductor is the bundle strand/thigh structure that tangles, and the stranded lay ratio of conductor is 12-18, and the filament diameter of copper wire can be to be set arbitrarily among the standard GB/T3956; The single wire fracture percentage elongation is not less than 15%.
Described uvioresistant, the anti-bird pest plateau of protection against rodents special cable, it is characterized in that: described cable conductor quantity is the 2-61 core, the cross-sectional area of conductor area is 1.0-400mm
