Abstract

The invention discloses a copper core cross-linked polyethylene-insulated non-magnetic metal band low-smoke zero-halogen flame-retardant cable. The cable comprises a cable core which is formed by twisting three flame-retardant insulated wire cores; the gap of the cable core is filled with a refractory expansion band, a second aluminum foil woven fabric flame retarding layer is arranged outside thecable core, a non-magnetic metal band is arranged outside the second aluminum foil woven fabric flame retarding layer, and a flame-retarding cable pipe is arranged outside the non-magnetic metal band; and each flame-retardant insulated wire core is formed by an aluminum conductor, a cross-linked polyethylene insulation layer wrapping the aluminum conductor in an extruding mode and a first aluminum foil woven fabric flame retarding layer arranged outside the cross-linked polyethylene insulation layer. The cable has the performances of flame retarding, fire proofing and the like.

Description

Technical field [0001] The invention relates to the field of wires and cables, in particular to a copper core cross-linked polyethylene insulated non-magnetic metal tape halogen-free low-smoke flame-retardant cable. Background technique [0002] Fire is a disaster caused by burning out of control in time and space. Among various disasters, fire is one of the main disasters that most often and most commonly threaten public safety and social development. [0003] With the continuous development of society, while social wealth is increasing, the risk of fires is also increasing, and the danger of fires is also increasing. According to statistics, the average annual loss of fire in my country in the 1970s was less than 250 million yuan, and the average annual loss of fire in the 1980s was less than 320 million yuan. In the 1990s, especially since 1993, the direct property losses caused by fires have risen to an average of more than one billion yuan per year. According to China's fir...
