Wholesale High Voltage PVC/XLPE Insulated Power Cable XLPE Copper Wire Conductor Electrical Cable Di

Product feature and purpose:
Overhead CableOverhead cable is an overhead conductor equipped with an insulating layer and a protective sheath. It is a special cable made by a process similar to that of cross-linked cable. It is a new power transmission method between overhead conductors and underground cables. Overhead cables are single-core, according to its different structure can be divided into duralumin wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three-core pattern structure (core can be duralumin or hard copper wire). It has the main features of high power supply reliability, good power supply security, convenient erection and maintenance, and reasonable economy. The main technical parameters of overhead cable include weather resistance, insulation level, inner and outer semi-conductive shielding layer, which is widely used in power transmission at home and abroad. Overhead cables are designed and manufactured with a variety of factors in mind to ensure their reliable operation and safety in a variety of environmental conditions. For example, weather resistance guarantees the service life of the cable in different climatic conditions, the insulation level prevents the risk of current leakage and short circuit, and the internal and external semi-conductive shielding helps to optimize the current distribution and reduce the strength of the electric field, thereby protecting the cable from damage. In addition, the diversity and customizability of overhead cables make it possible to adapt to different voltage and current needs, whether it is urban power supply or industrial power consumption, the right solution can be found. In general, as an important mode of power transmission, overhead cables not only play a key role in the power network of modern cities and industrial areas, but also play an indispensable role in the popularization of electricity in rural and remote areas. Through its unique design and excellent performance, overhead cables provide a stable and reliable guarantee for the global power supply.
Operative standard:

GB/T 12706,IEC 60502 and relevant domestic and international standard.For example,BS,VDE,JIS,AEIC,and GB JL LHA NRLH JK series so on.

Operational performance:
The maximum allowable operating temperature of the cable conductor:90 C in normal condition and 250 C in case of short circuit (maximum duration of short circuit is 5s).
