Abstract
The utility model discloses a low-smoke halogen-free flame-retardant A type stainless steel armored cable. The cable comprises a cable core and a protective layer, wherein a non-woven cloth wrapping tape is wrapped outside the cable core; a scraping adhesive tape cushion layer is wrapped outside the wrapping tape; embossed stainless steel is arranged outside the cushion layer, and is longitudinally covered and wrapped on the cushion layer by welding; a flame-retardant inner protective layer is wrapped outside embossed stainless steel by extruding, and a cross-linked flame-retardant polyolefin outer protective layer is wrapped outside the inner protective layer by extruding; the cable core is formed by intertwining insulating shielded wire cores, and inorganic fiber fillers are arranged in gaps of the cable core; and each insulating shielded wire core is formed by arranging a conductor shielding layer outside a conductor, wrapping a cross-linked polyethylene insulating layer outside the conductor shielding layer by extruding, arranging an aluminum-plastic composite tape insulating shielding layer outside the insulating layer and wrapping a copper strip outside the insulating shielding layer, and color stripes are arranged on the copper strip. The low-smoke halogen-free flame-retardant A type stainless steel armored cable has high flame retardation, meets A type flame retardation requirements, and has excellent mechanical shock resistance.
Description
Technical field
The utility model discloses a kind of structure of cable, be specifically related to a kind of low-smoke non-halogen flame-retardant category-A stainless steel armoured cable, belong to the cables manufacturing technical field.
Background technology
Tradition band-armored and aluminium sheath embossing armouring type cable; Protection against rodents ant, bendability, protection against the tide, the anticorrosion and mechanical shock resistance of telecommunication cable can be guaranteed, but high-level (category-A) fire-retardant requirement of electric power supply system for subway 35kV and the safe occasion of following height can't be satisfied.In addition, the sheath of traditional armouring type cable or mechanical strength are high, and fire resistance is poor; Fire resistance is good, bad mechanical property; In a word, the mechanical strength of sheath and flame-retarding characteristic can not compatible present situation have restricted the performance of cable performance.
The utility model content
The utility model technical problem to be solved provides a kind of low-smoke non-halogen flame-retardant category-A stainless steel armoured cable, and this product fire resistance is good, reaches the fire-retardant requirement of category-A, has good mechanical shock resistance.
For solving the problems of the technologies described above, the utility model low-smoke non-halogen flame-retardant category-A stainless steel armoured cable comprises cable core and sheath; The outer wrapped nonwoven fabrics band of cable core; The outer wrapped rubberized tape resilient coating of scraping of band, resilient coating is provided with the embossing stainless steel outward, and the vertical bag welding of embossing stainless steel is wrapped on the resilient coating; The embossing stainless steel extrudes fire-retardant sheath outward, and sheath extrudes the fire-retardant polyolefine material outer jacket of cross-linking type outward; Said cable core forms by the insulation shielding core is stranded, and the gap of cable core is provided with the inorfil filler; The insulation shielding core is provided with conductor shield outward by conductor, and conductor shield extrudes crosslinked polyetylene insulated layer outward, the outer wrapped aluminium-plastic tape insulation screen of insulating barrier, and the outer wrapped copper strips of insulation screen constitutes, and copper strips is provided with vitta.
The utlity model has following beneficial effect: the first, adopt the buffering band wrapped, cable core preserves from when guaranteeing that cable carries out aluminium sheath welding and embossing.The second, sheath comprises two-layer, sheath and outer jacket, and the fire resistance of sheath is good, and the mechanical performance of outer jacket is strong, and sheath has concurrently fire-retardant and mechanical performance, and the mechanical strength and the flame-retarding characteristic that have solved the traditional cable oversheath can not compatible technical problems.The 3rd, adopt stainless steel to carry out armouring, good corrosion resistance, moistureproof, protection against rodents ant.
