What are the main features of ABC overhead insulated cable
Overhead insulated cables are used for overhead power lines below voltage 0.6/1KV. Including 1-core, 2-core, 3-core, 4-core, Covered line wire, Duplex service drop, Triplex service drop, Quandruplex service drop.
. Lay in overhead electric line of rate voltage 600/1000v, it transmit power.
. The laying temperature of the cable is not less than -20 degrees
. The long-term allowable working temperature of the cable conductor is not more than 70 degrees.
. It is benefit improving and enhancing the safety and reliability of the power distribution system, greatly reducing the risk of personal injury 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 The power supply utilization rate of the line;
. Good insulation performance. Aerial bundled cables have better insulation performance than bare conductors due to an extra layer of insulation, which can reduce the line-to-phase distance, reduce the insulation requirements for line support members, and increase the number of loops erected on the same pole.
. Good anti-corrosion performance.
. It is convenient for high voltage to penetrate into the load center to improve voltage quality and reduce power loss;
. Prevent external force damage, reduce the influence of external factors such as trees, flying objects, metal films and dust.
