Abstract
The utility model provides a cold-resistant cable of high altitude, includes the transposition copper wire, the transposition copper wire comprises a plurality of transposition copper wire monomers together, transposition copper wire center department be equipped with silica gel filler strip, the copper wire monomer including inside and outside copper wire body, the insulating canning of silica gel, the aluminium system canning of cup jointing, the seamless crowded package in the circumference outside of transposition copper wire has cold-resistant band, gap department between cold-resistant band and the transposition copper wire packs silica gel material, the circumference outside cladding of cold-resistant band have the polyvinyl chloride sheath. The cable uses the silica gel insulating sheath as the insulating sheath of the cable, the working temperature range is-40 ℃ to 180 ℃, and meanwhile, the aluminum sheath is arranged outside the silica gel insulating sheath, so that the aluminum sheath effectively avoids the invasion of water vapor to the insulation and also avoids the aging of strong ultraviolet rays to the cable insulation. Meanwhile, the aluminum sheath can be used as a grounding wire core, so that the cost of the cable is greatly reduced.
Description
Technical Field
The utility model relates to a cold-resistant cable of high altitude.
Background
In the prior art, cold-resistant cables generally adopt cold-resistant polyvinyl chloride as the insulation and sheath of the cables. Because the temperature difference between day and night is large in high altitude areas, water vapor is large, sunlight and ultraviolet rays are strong, the common cold-resistant cable is reliable and weak, and the service life of the cable is short. The main reasons are that moisture penetration into insulation and jacketing materials affects electrical performance, and ultraviolet light and large temperature differences in turn accelerate the aging of the jacketing and insulation of the cable.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a cold-resistant cable of high altitude is provided, its invasion of having avoided steam to cable insulation layer has also avoided strong ultraviolet ray to cause cable insulation's ageing.
For solving the technical problem, the utility model provides a cold-resistant cable of high altitude, including the transposition copper wire, the transposition copper wire comprises a plurality of transposition copper wire monomers together, transposition copper wire center department be equipped with the silica gel filler strip, the copper wire monomer including inside and outside copper wire body, silica gel insulating sheath, the aluminium system sheath that cup joints, the seamless crowded package in the circumference outside of transposition copper wire has cold-resistant band, gap department between cold-resistant band and the transposition copper wire packs silica gel material, the circumference outside cladding of cold-resistant band have the polyvinyl chloride sheath.
Preferably, the cold-resistant wrapping tape is a silica gel tape, a glass fiber tape or a halogen-free tape.
For the sake of simple explanation, the following is the present cable for short for a high altitude cold-resistant cable of the present invention.
The cable has the advantages that: the cable uses the silica gel insulating sheath as the insulating sheath of the cable, the working temperature range is-40 ℃ to 180 ℃, and meanwhile, the aluminum sheath is arranged outside the silica gel insulating sheath, so that the aluminum sheath effectively avoids the invasion of water vapor to the insulation and also avoids the aging of strong ultraviolet rays to the cable insulation. Meanwhile, the aluminum sheath can be used as a grounding wire core, so that the cost of the cable is greatly reduced.

Detailed Description
See fig. 1 a cold-resistant cable of high altitude, including the transposition copper wire, the transposition copper wire comprises a plurality of transposition copper wire monomers 1 together, transposition copper wire center department be equipped with silica gel filler strip 2, copper wire monomer 1 including the copper wire body 11, silica gel insulating sheath 12, the aluminium system sheath 13 that cup joint inside and outside, the seamless crowded package in the circumference outside of transposition copper wire has cold-resistant band 3, gap department between cold-resistant band 3 and the transposition copper wire packs silica gel material 5, the circumference outside cladding of cold-resistant band 3 have polyvinyl chloride sheath 4.
The cold-resistant wrapping tape 3 is a silica gel tape, a glass fiber tape or a halogen-free tape.
The cable has the advantages that: the cable uses the silica gel insulating sheath 12 as an insulating sheath of the cable, the working temperature range is-40-180 ℃, meanwhile, the aluminum sheath 13 is arranged outside the silica gel insulating sheath 12, and the aluminum sheath 13 effectively avoids the invasion of water vapor to the insulation and also avoids the aging of strong ultraviolet rays to the cable insulation. Meanwhile, the aluminum sheath 13 can be used as a grounding wire core, so that the cost of the cable is greatly reduced.
