　　JKLYJ-10KV-70 specification high-voltage all aluminum overhead insulated wire manufacturer offers high quality and large quantity. Welcome to call

　　Characteristics of overhead insulated lines:

　　Good insulation performance. Due to the addition of an insulation layer, overhead insulated conductors have superior insulation performance compared to bare conductors, which can reduce the distance between lines, lower the insulation requirements for line supports, and increase the number of circuits installed on the same pole.

　　Good anti-corrosion performance. Due to the insulation layer on the outer layer, overhead insulated wires are less susceptible to oxidation and corrosion than bare wires, and have stronger corrosion resistance, which can extend the service life of the line.

　　Prevent external damage, reduce the influence of external factors such as trees, flying objects, metal films, and dust, and minimize phase to phase short circuits and grounding accidents.

　　The strength meets the requirements. Although the insulated wire lacks a steel core, it is tough and makes the mechanical strength of the entire wire meet the requirements of stress design.

　　The use of insulated conductors instead of bare conductors for 10kV and below high-voltage insulated overhead lines is a new technology in the construction and renovation of urban distribution networks. It has a series of advantages of buried cables and can overcome many disadvantages of overhead bare wires. It can solve some problems encountered by conventional bare wires during operation and is much cheaper than buried cables. Therefore, there is a certain development prospect in the construction of urban distribution networks.

　　Compared to lines constructed with bare conductors, high-voltage insulated overhead lines have the following main advantages:

　　① Conducive to improving and enhancing the safety and reliability of the power distribution system, greatly reducing the risk of personal electric shock injury. Insulated wires can prevent phase to phase short circuits caused by external objects, reduce the number of power outages during pole closing operations, reduce maintenance workload, and improve the power supply utilization rate of the line;

　　② Beneficial for urban construction and greening work, reducing the amount of tree pruning along the route;

　　③ It can simplify the structure of line towers and even lay them along walls, saving line materials and beautifying urban streets;

　　④ Facilitating the penetration of high voltage into the load center to improve voltage quality and reduce energy loss;

　　⑤ Saved the space occupied by overhead lines, making it easier for overhead lines to pass through narrow passages. The line corridor has been reduced by half compared to overhead bare lines;

　　⑥ Save line energy loss, reduce voltage loss, and the line reactance is only one-third of that of ordinary bare wire lines;

　　⑦ Reduce wire corrosion, thereby improving the service life and distribution reliability of the line accordingly;

　　⑧ Reducing the gravity requirements of the line, decreasing the investment in matching parts, and lowering the labor intensity of workers during wire installation;

　　⑨ Reduced the insulation requirements for line support components and increased the number of circuits on the same pole; Due to the improvement of line technology, the maintenance workload has been reduced, the maintenance cycle has been extended, and the time of power outages caused by maintenance has been reduced.

　　The disadvantages are:

　　① The allowable current carrying capacity of high-voltage insulated overhead lines is smaller than that of bare wires, because after adding a plastic layer, the heat dissipation of the wires is poor. The shape of overhead insulated wires should be raised by one level compared to usual. If the original 70mm2 wire is used, it should be matched to 95mm2.

　　② The diameter of high-voltage insulated overhead lines is relatively large, and with the addition of plastic sheaths, the diameter is one grade larger than that of steel cored aluminum stranded wires with the same cross-section. Although insulated wires have many advantages, their unit cost is higher than bare wires, about twice as high for medium voltage lines and about 25% higher for low voltage lines.
