APPLICATION

BURY CABLE supplies this 600/1000V single core mica XLPE LSZH cable for essential power circuits in buildings, transport facilities and industrial installations. The mica glass tape forms the fire barrier, while the LSZH sheath supports low-smoke and halogen-free requirements. Use ducts, trenches and routes specifying armoured single-core cables as part of the specified cable installation system.

STANDARDS

The product design strictly adheres to international standards such as IEC 60502-1, guaranteeing exceptional and reliable fundamental performance.
