This cable is a fire safety cable complying with the basic design standard of BS 7211:2012, with a rated voltage of 300/500V. It is specifically designed for scenarios with stringent requirements for electrical safety, fire resistance performance, and environmental protection. Adopting high-purity annealed copper conductors, a mica glass tape fire barrier, and an XLPE insulation structure, paired with a low-smoke zero-halogen (LSZH) outer sheath, it combines excellent flame retardancy, circuit integrity, and environmental protection characteristics. It is an ideal choice for emergency circuits and regular wiring in critical locations such as buildings, subways, and hospitals.
