What are the advantages of overhead insulated cables compared to bare wires? 2025-09-23

Compared to bare wires, Yindu overhead cables have obvious advantages: high safety: the insulation layer can effectively prevent phase to phase short circuits and grounding faults caused by foreign object overlap, tree contact, etc.

Can mineral fire-resistant cables (such as BTTZ, YTTW) really prevent fire? 2025-09-23

Yes, mineral fire-resistant cables are truly fire-resistant cables that can maintain line integrity and power supply for at least 180 minutes in flames ranging from 950 ℃ to 1000 ℃.

What are the main applications of YJV cables from Yindu Cable? 2025-09-23

Yindu YJV cable is suitable for fixed installation in transmission and distribution grids, industrial and mining enterprise power supply lines with AC rated voltage of 0.6/1kV and below. Widely used in urban power grids, power stations, high-rise buildings, factories, tunnels and other places that require high reliability of power supply.

What are the advantages of cross-linked polyethylene insulated power cables (such as YJV) compared to ordinary PVC cables (VV)? 2025-09-23

The main advantages are its heat resistance and current carrying capacity. The cross-linking process transforms polyethylene materials from thermoplastic to thermosetting, with a long-term allowable working temperature increased from 70 ℃ to 90 ℃, and a maximum withstand temperature of 250 ℃ during short circuit. This means that under the same cross-section, YJV cables have higher current carrying capacity, stronger overload capacity, are more energy-efficient, and have a longer service life.
