Fire Resisting Cables
600/1000V Mica+LSZH Insulated, Non-sheathed Power Cables to BS EN 50525-3-31 (Single Core)
FFX100 1mZ1-R(CU/MGT+LSZH 600/1000V Class 2)
General Description
FFX100 1mZ1-R fire resisting cable conforms to BS EN 50525-3-31 standard, featuring annealed copper Class
2 conductor, mica glass tape fire barrier, and LSZH (low smoke zero halogen) thermoplastic insulation. Rated
600/1000V with 70°C operating temperature, it passes IEC 60331-21, BS 6387 circuit integrity, IEC 60332
flame retardance, IEC 60754 halogen-free, and IEC 61034-2 low smoke emission tests. Designed for power
stations, mass transit underground systems, airports, petrochemical plants, hotels, hospitals, and high-rise
buildings, this single-core fire-rated cable maintains critical emergency power supply during fire incidents.
APPLICATION
600/1000V Mica+LSZH Insulated, Non-sheathed Power Cables to BS EN 50525-3-31 (Single Core) are
mainly used in power stations, mass transit underground passenger systems, airports, petrochemical plants,
hotels, hospitals and high-rise buildings.
