Description
Technical Field
The utility model relates to a power cable, specifically speaking relate to a low wind pressure temperature resistant 105 ℃ aerial insulation increase-volume cable.
Background
At present, overhead insulated cables are commonly used for power transmission of suburb and rural power grids in China, and the common overhead insulated cables are generally cylindrical. The cylindrical cable has large swing amplitude in strong windy weather, so that a cable support generates large pressure on an electric pole and the like, the operation of a power line is greatly influenced, meanwhile, the strength of the support is required to be increased in the design process, the load requirement in a strong wind state is met, the raw material cost of the cable support is increased, and the construction cost of the line is increased.
Under the large background of advocating energy conservation and emission reduction and environmental protection in China, more attention should be paid to the potential of excavating the existing network from the expansion of the power grid in order to solve the contradiction between the increasing power load and the difficulty in cable line construction from the perspective of sustainable development and environmental protection, so that the transmission capacity of the power transmission network is improved. Particularly in the aspects of new rural construction and distribution network capacity increase transformation, how to ensure the reliability of safe operation of the power cable under a high-load condition is required to ensure that the maximum operation temperature can be improved on the basis of meeting the power load requirement so as to improve the current-carrying capacity of the power cable, thermal aging and electrical aging insulation faults are avoided, and the power cable can achieve the effect of dynamic capacity increase according to the real-time environment condition of cable operation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a low wind pressure temperature resistant 105 ℃ aerial insulation increase-volume cable, use the utility model discloses back pressure differential around the cable when can reducing the wind and blow can reach the purpose of increase-volume simultaneously.
In order to solve the technical problem, the utility model relates to a low wind pressure temperature resistant 105 ℃ aerial insulation increase-volume cable has the conductor sinle silk, and the outer cladding of conductor sinle silk has insulating layer, its characterized in that: the conductor wire core is 63-percent IACS high-conductivity aluminum with a round molded line twisted and compacted, the insulating layer is a heat-resistant 105 ℃ weather-resistant chemical crosslinking polyethylene insulating layer, and arc-shaped grooves are formed in the outer wall of the heat-resistant 105 ℃ weather-resistant chemical crosslinking polyethylene insulating layer at intervals longitudinally.
The utility model discloses in, be formed with behind the arc recess of longitudinal separation equipartition on the outer wall of insulating layer, pressure differential around the cable when can reducing wind and blow, wind-force is big more, reduces more, and then has reduced wind and has blown and cause the produced tension of cable reciprocal swing to destroy, has improved the stability that the cable laid, has improved circuit security. Meanwhile, the design strength of the cable support can be greatly reduced, and the line construction cost is reduced. The utility model discloses well conductor sinle silk adopts round type line transposition after sticising 63%IACS high conductivity aluminium, reaches the purpose that improves transport capacity, reduces the circuit loss. After the insulating layer is made of the heat-resistant 105 ℃ weather-resistant chemical crosslinked polyethylene, the working temperature of the overhead insulated cable is increased to 105 ℃, compared with the working allowable temperature of the common crosslinked polyethylene insulated overhead insulated cable which is 90 ℃, the working temperature of the line is increased by 15 ℃, the transmission capacity of the urban network 10kV overhead insulated distribution line is greatly improved, and the purpose of capacity increase is achieved.
