Advantage of Multi-core Overhead Insulated Cable

Share:
Overhead insulated cables are mainly used for the construction and transformation of urban distribution networks. They are cables that use insulated wires instead of bare wires. Not only can it overcome many shortcomings and operational problems of overhead bare wires, but also the price is relatively cheap. Next, the editor of Jinhaotai talks about the advantages and disadvantages of using overhead insulated cables.
 
Advantages of overhead insulated cables

(1) The structure of the line pole and tower can be simplified, and it can even be laid along the wall, which not only saves line materials, but also beautifies the city streets

(2) Conducive to improving and enhancing the safety and reliability of the power distribution system, greatly reducing the risk of personal injury and death due to electric shock. Insulated wires can prevent phase-to-phase short circuits caused by foreign objects, reduce the number of power outages during pole line operation, reduce maintenance workload, and increase Power utilization rate

(3) Save the power loss of the line and reduce the voltage loss, the line reactance is only 1/3 of the line reactance of ordinary bare conductors

(4) Go deep into the load center at high voltage to improve voltage quality and reduce power loss

(5) Reduce the gravity requirements of the line, reduce the investment in matching parts, and reduce the labor intensity of workers when setting up the line

(6) The space occupied by overhead lines is saved, and it is convenient for overhead lines to pass through narrow passages. Reduced the line corridor, compared with the overhead bare line, the line corridor can be reduced by 1/2

(7) Reduce wire corrosion, thus correspondingly improve the service life of the line and the reliability of power distribution

(8) Reduce the insulation requirements for line support parts and increase the number of circuits on the same pole; 10 due to the improvement of line technical conditions, the maintenance workload is reduced, the maintenance period is extended, and the time for power outages due to maintenance is reduced.
