Execution standard of Two-core Parallel Cluster Overhead Cable
GB/T 12527-2008 Rated voltage up to and including 1 kv overhead insulated cable.
Characteristics of Two-core Parallel Cluster Overhead Cable
Bundle conductor line loss is low, line loss.suggestions between 5-10%;Saving time and labor for construction is convenient, and reduce the cost of installation;Combination of tensile force of strong, high safety, preventing electricity-stolen, prevent leakage;Low engineering cost, reduce the pole, cross arm and porcelain, to reduce the pole height.
Main purpose and use characteristics
Wire into a cluster shape combination,the anti-large-breaking force doubled than the single line, reducing single-phase disconnection accident. In the wind pressure, frost and other tension between the role of parallel insulation is not under pressure, improve the safety factor, the anti-lightning, anti-tamper, anti-leakage effect was improved. Because of its combination of splitability so that the branch is easy to bridge, variable capacity and convenient combination. According to the zero line identification, the phase sequence identification is clear, to prevent the wrong phase sequence.
Parallel bundle conductor line reduce the tower, cross arm and porcelain pieces, save a lot of metal. As the insulation can reduce the tower height, don’t affected by the trees, buildings and other complex environment, can be completely eliminated Poles and along the wall laying, the project cost is low. In addition, compared with single-line, construction is simple, save time and labor, reduce construction costs. Compared with the conventional overhead bare wire mode parallel cluster wire with low operating costs, long-term benefits of obvious advantages.
