1000V Rz1-K cable has a rated voltage of 0.6/1kv and a specification of 1×240mm, which is a halogen-free cable. It adopts a flexible copper conductor. Flexible copper has good flexibility, which is convenient for laying and installation in complex environments. At the same time, it has excellent conductivity and can transmit electricity efficiently. The insulation layer is made of XLPE material. XLPE has strong insulation performance and good temperature resistance, which can ensure the stability of the cable during power transmission and reduce potential safety hazards such as electric leakage. The jacket is made of LSZH material. LSZH jacket has the characteristics of low smoke and halogen-free. It will not release a large amount of toxic and harmful gases and thick smoke when burning, so it has extremely high safety. This cable combines the flexibility of flexible copper conductor, the reliability of XLPE insulation and the safety of LSZH jacket. It is suitable for power transmission scenarios with high requirements for cable flexibility, insulation performance and fire safety, such as internal power distribution of buildings and power supply of industrial equipment. It can operate stably at the voltage level of 0.6/1kv and meet relevant power transmission needs.
