Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, this embodimentOnly, for explaining the present invention, do not form limiting the scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of low smoke and low halogen power cable, and described cable from inside to outside successivelyComprise core 1, inner sheath 2, mica belt 3, metal shielding 4, oversheath 5; It is oblate that oversheath 5 is, and described core 1 is by interiorTo comprising successively conductor 10, halogen-free flameproof band 11, insulating barrier 12 and Mica tape layer 13 outward; Described insulating barrier 12 and in protectCover 2 all adopts low smoke and low halogen sizing material, and inner sheath 2 is integral-filled between core 1, and the machinery that can effectively strengthen cable is strongDegree, and make cable there is good low-smoke low-halogen and fire resistance. Described metal shielding 4 is the vertical inclusion of bimetallic stripStructure, and the wrapped bonding station of inside and outside double layer of metal band is not overlapping, ensures that cable has high strength; Described oversheath 5 is low halogenFire-retardant polyolefin jacket. The outer setting of described oversheath 5 has fire resistance fibre cushion 6, to metal shielding 4 outside powerfulThe distortion causing under power effect cushions. The quantity of described core 1 is two, and all cores 1 are in one line. Described phaseBetween adjacent line core 1, be provided with gap, make core 1 can have separate space, can effectively strengthen the mechanical strength of cable, and favourableIn the extrusion packing of inner sheath 2.
Described low smoke and low halogen sizing material is made up of the raw material of following parts by weight: 100 parts of polyvinyl resins, hydration boric acid30 parts, zinc, 80 parts, aluminium hydroxide, 8 parts of phosphate, 10 parts of cyclopentadienyl group iron, 15 parts of molybdate compounds, 7 parts, calcium carbonate, phosphoric acid1 part of ester plasticizer, 1.2 parts, polyesters plasticizer, 2 parts of plasticizer DOPs, 1 part of antioxidant MB, 2 parts of anti-aging agent RDs, paraffin7 parts of oil, 2 parts of vulcanization aids, 10 parts of mica powders. Described polyvinyl resin is linear polyethylene resin and elastic polyethylene resinWeight ratio is the hybrid resin of 1:1. Increase mica powder and can effectively strengthen the resistance to elevated temperatures of sizing material, and adopt hydration zinc borate andAluminium hydroxide as fire retardant, adopt phosphate, cyclopentadienyl group iron, molybdate compound, calcium carbonate as antismoke agent, adopt phosphorusEsters of gallic acid plasticizer, polyesters plasticizer and plasticizer DOP be as plasticizer, makes cable meet other physical propertiesUnder prerequisite, can effectively strengthen the low smoke and low halogen performance of cable.
The cable that the present embodiment provides has high strength, low smoke and low halogen is functional, practical; And structure letterSingle, easily processing, improved operating efficiency; Cost is low, has saved manufacturing cost.
