Abstract
The invention discloses an insulating and shielding double-sheath cable resistant to an acid and a base. The insulating and shielding double-sheath cable is composed of grounded cable cores, an ethylene propylene rubber insulation layer, a tinned copper wire shielding layer, a low-smoke and zero-halogen polyolefin sheath layer and a chlorosulfonated polyethylene sheath layer. Three sets of the grounded cable cores are arranged, the ethylene propylene rubber insulation layer wraps three sets of the grounded cable cores, the tinned copper wire shielding layer wraps the ethylene propylene rubber insulation layer, the low-smoke and zero-halogen polyolefin sheath layer wraps the tinned copper wire shielding layer, and the chlorosulfonated polyethylene sheath layer wraps the low-smoke and zero-halogen polyolefin sheath layer. The insulating and shielding double-sheath cable is widely applied to the field of chemical engineering petroleum and the like, is excellent in acid and base resistance and high temperature resistance, and has the advantages of resisting ageing and oxidizing and being high in tensile strength.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of acid and alkali-resistance insulation shielding double sheathed cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as chemical petroleum, acid-proof alkaline to cable, the requirement of resistance to elevated temperatures aspect are all high especially, only meet the requirements, and could improve the fail safe while manufacturing in these fields.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of acid and alkali-resistance insulation shielding double sheathed cable with the strong and good resistance to elevated temperatures of acid-proof alkaline.
The present invention takes following technical scheme to realize: a kind of acid and alkali-resistance insulation shielding double sheathed cable, it is by ground connection cable core, ethylene propylene rubber insulated layer, tinned copper wire screen, low-smoke halogen-free polyolefin restrictive coating and chlorosulfonated polyethylene sheath layer composition, described ground connection cable core is three groups, outside three groups of ground connection cable cores, wrap up the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, wrap up one deck tinned copper wire screen, outside described tinned copper wire screen, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, outside described low-smoke halogen-free polyolefin restrictive coating, wrap up one deck chlorosulfonated polyethylene sheath layer, described ethylene propylene rubber insulated layer inside is extruded with three group aluminum alloy conductor cable cores.
Described aluminium alloy conductor cable core inside is extruded with 19 aluminium alloy conductors.
Described ground connection cable core is made up of aluminium conductor, belting layer, nickel strap screen, nickel conductor and silicone rubber insulation layer.
