This series of cables (including models such as Yjv22 and N2xby) are special underground power transmission cables of 0.6/1kV, with a specification of 3*150+95sqmm. They take copper conductors as the core and are equipped with a double steel tape armored structure, suitable for complex underground laying environments.​ The conductors are made of high-purity copper. Three 150sqmm main wires are responsible for power transmission, and one 95sqmm ground wire ensures safety, with high conductivity and low loss. The insulation layer is suitable for 0.6/1kV voltage level, with stable insulation performance, and can withstand the test of humid underground environments for a long time.​ The double steel tape armored layer is a core protection highlight, which can resist soil pressure, mechanical impact and rodent bites during underground laying. The outer sheath has corrosion-resistant and anti-aging properties, adapting to complex underground conditions such as acid-base and water vapor.​ This cable is mainly used for underground power trunk lines, municipal power grid laying and underground distribution systems in industrial parks. It can meet the needs of medium and high-voltage power transmission and provide high-strength and high-reliability transmission guarantee for underground power networks.
