Abstract
The invention discloses a high-temperature-resistant and flame-retardant medium-voltage cable. The high-temperature-resistant and flame-retardant medium-voltage cable comprises a main cable core, an armor layer, an inner sheath layer, a copper-strip armor layer, an insulation layer, silver-plated aluminum belt armor layer and an outer sheath layer, wherein the main cable core comprises a conductor, an ethylene-propylene-diene monomer rubber insulation layer, a non-magnetic metal armor layer and a zinc-plated copper-wire shielding layer, and the inner sheath layer and the outer sheath layer are chlorosulfonated ethylene propylene sheath layers. The cable has the advantages of being temperature resistant, oil resistant, ultraviolet-light resistant and waterproof and containing chloride, the mechanical performance of the cable is greatly improved, no poisonous gas is emitted when the cable catches a fire, and the cable can be freely twisted along with a windmill.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of heat-resistant fireproof midium voltage cable.
Background technology
This cable conductor does not breaks, and insulation and sheath material the most do not occur cracking and be short-circuited because of rainwater.But, the most also there is no a kind of tension with excellence and the tension low-voltage cable that blocks water of block-water performance.
Summary of the invention
This patent is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of tension with excellence and the heat-resistant fireproof midium voltage cable of block-water performance.
nullThe present invention takes techniques below scheme to realize: a kind of heat-resistant fireproof midium voltage cable，It is by master core、Armor、Inner restrictive coating、Copper strips armor、Insulating barrier、Silver-plated aluminium strip armor and external sheath layer composition，Described master core is provided with three groups，It is extruded in inside armor，Three silver-plated steel wire tension silks are also extruded inside described armor，Described master core is by conductor、Ethylene propylene diene rubber insulating barrier、Nonmagnetic metal armor and zinc-plated shielding layer of copper wires composition，One layer of inner restrictive coating of the outer wrapping of described armor，One layer of copper strips armor of the outer wrapping of described inner restrictive coating，Outer wrapping one layer insulating of described copper strips armor，The silver-plated aluminium strip armor of the outer wrapping of described insulating barrier one layer，One layer of external sheath layer of outer wrapping of described silver-plated aluminium strip armor，Described copper strips armor is provided with three groups，Uniformly extrude in insulating barrier，Described inner restrictive coating and external sheath layer are chlorosulfonation second propylene restrictive coating.
A length of 2 millimeters of the cross-sectional diameter of described master core conductor.
The method have the advantages that this kind of cable has heatproof, oil resistant, ultraviolet resistance, waterproof chloride advantage in sum, the mechanical performance making cable is greatly improved, releasing without toxic gas when fire met by cable, cable can be with windmill FREE TORSION simultaneously.
Accompanying drawing explanation
