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.
