Abstract

The utility model discloses an armoured tensile double-sheath cable, which is constituted of grounding cable cores, an ethylene propylene rubber insulating layer, a galvanized aluminium wire armor, a low-smoke halogen-free polyolefin sheath layer, an aluminium strip armor and a chlorosulfonated polyethylene sheath layer. Three grounding cable cores are provided. The three grounding cable cores are coated with the ethylene propylene rubber insulating layer. The outside of the ethylene propylene rubber insulating layer is coated with the galvanizing aluminium wire armor. The outside of the galvanizing aluminium filament armor is coated with the low-smoke halogen-free polyolefin sheath layer. The outside of the low smoke halogen free polyolefin sheath layer is coated with the aluminium strip armor. The cable provided by the utility model is widely applied in the fields of chemical petroleum and the like, and has the advantages of excellent performances of acid and alkali resistance and high temperature resistance and meanwhile has the advantages of aging resistance, oxidation resistance and high tensile strength.

Description

A kind of armouring tension double sheathed cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of armouring tension 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of armouring tension double sheathed cable with the strong and good resistance to elevated temperatures of acid-proof alkaline.

The utility model takes following technical scheme to realize: a kind of armouring tension double sheathed cable, it is by ground connection cable core, ethylene propylene rubber insulated layer, zinc-plated aluminium wire armoured layer, low-smoke halogen-free polyolefin restrictive coating, aluminium strip armour 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 the zinc-plated aluminium wire armoured layer of one deck, outside described zinc-plated aluminium wire armoured layer, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, outside described low-smoke halogen-free polyolefin restrictive coating, wrap up one deck aluminium strip armour, 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.

Described aluminium conductor is 5, is extruded in belting layer inside, and described nickel conductor is 8, is extruded in nickel strap screen inside.

The utlity model has in sum following beneficial effect: the utility model is widely used in the fields such as chemical petroleum, there is good acid-proof alkaline and good resistance to elevated temperatures, also have simultaneously ageing-resistant, the advantage that resistance to oxidation and pull resistance are strong.

Embodiment

As shown in Figure 1, a kind of armouring tension double sheathed cable, it is by ground connection cable core 1, ethylene propylene rubber insulated layer 2, zinc-plated aluminium wire armoured layer 3, low-smoke halogen-free polyolefin restrictive coating 4, aluminium strip armour 5 and chlorosulfonated polyethylene sheath layer 6 form, described ground connection cable core 1 is three groups, outside three groups of ground connection cable cores 1, wrap up the ethylene propylene rubber insulated layer 2 of one deck, outside described ethylene propylene rubber insulated layer 2, wrap up the zinc-plated aluminium wire armoured layer 3 of one deck, outside described zinc-plated aluminium wire armoured layer 3, wrap up one deck low-smoke halogen-free polyolefin restrictive coating 4, outside described low-smoke halogen-free polyolefin restrictive coating 4, wrap up one deck aluminium strip armour 5, described ethylene propylene rubber insulated layer 2 inside are extruded with three group aluminum alloy conductor cable cores 7.

Described aluminium alloy conductor cable core 7 inside are extruded with 19 aluminium alloy conductors 71.

Described ground connection cable core 1 is made up of aluminium conductor 11, belting layer 12, nickel strap screen 13, nickel conductor 14 and silicone rubber insulation layer 15.

Described aluminium conductor 11 is 5, is extruded in belting layer 12 inside, and described nickel conductor 14 is 8, is extruded in nickel strap screen 15 inside.

The permission bending radius of this cable is the outside diameter of cable 16 times; Cable permission work maximum temperature is 70 DEG C; The shielding rejection coefficient of this cable is less than 0.7; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.

The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
