The invention discloses an environment-friendly mid-
voltage fire resistant cable, which comprises an aluminum
alloy conductor arranged in the middle of the cable, wherein a conductor shielding layer, a cross-linked
polyethylene insulation layer and an insulation shielding layer are sequentially extruded on the aluminum
alloy conductor in a three-layer co-extruding manner; a
metal shielding layer is arranged outside the insulation shielding layer; an insulation wire core consists of the aluminum
alloy conductor, the conductor shielding layer, an
insulation layer, the insulation shielding layer and the
metal shielding layer; the
metal shielding layer, a composite fire resistant heat
insulation layer, a metal belt interlocked armored fireproof layer and an outer sheath layer are sequentially arranged outside the insulation shielding layer; three insulation wire cores and a filling material are stranded to form a cable core; and the composite fire resistant heat insulation layer consists of an inorganic heat insulation layer wrapped outside the cable core, a low-
smoke halogen-free antiflaming
polyolefin inner
protection layer extruded outside the heat insulation layer and an inorganic
fiber layer wrapped outside the inner
protection layer. The environment-friendly mid-
voltage fire resistant cable is a fire resistant aluminum alloy conductor mid-
voltage cable which is low in cost, has high bendability, high
fire resistance and high antiflaming performance, and is energy-saving and environment-friendly during manufacturing.
