Abstract

The utility model discloses a multi-conductor core armoured cable for electric power control. The cable is constituted of control cable cores, an ethylene propylene rubber insulating layer, a tin-coated copper wire armor, a Ni strip shielding layer, a poly tetrafluoroethylene insulating layer and a chloroprene rubber sheath layer. Three control cable cores are arranged. The three control cable cores are intertwisted and coated with the ethylene propylene rubber insulating layer outside. The ethylene propylene rubber insulating layer is coated with the tin-coated copper filament armor. The tin-coated copper filament armor is coated with the Ni strip shielding layer. The Ni strip shielding layer is coated with the poly tetrafluoroethylene insulating layer. The poly tetrafluoroethylene insulating layer is coated with the chloroprene rubber sheath layer. The cable provided by the utility model is widely applied in the fields of chemical petroleum and electric power and the like, and has the advantages of excellent performances of acid and alkali resistance and shielding properties and meanwhile has the advantages of aging resistance, oxidation resistance and high tensile strength.

Description

A kind of electric power is controlled many conductor thread cores armoured cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of electric power and controls many conductor thread cores armoured 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, electric power, requirement to the acid-proof alkaline of cable, heat-resisting shielding properties aspect is all high especially, only meets the requirements, and could improve in these fields the fail safe while manufacturing.

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 electric power with the strong and good shielding properties of acid-proof alkaline and controls many conductor thread cores armoured cable.

The utility model takes following technical scheme to realize: a kind of electric power is controlled many conductor thread cores armoured cable, it is by controlling cable core, ethylene propylene rubber insulated layer, tinned copper wire armour, nickel strap screen, polyfluorinated ethylene insulating barrier and chloroprene rubber sheath layer form, described control cable core is set to three groups, outside twisting together, wrap up three groups of control cable cores the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, wrap up one deck tinned copper wire armour, outside described tinned copper wire armour, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck polyfluorinated ethylene insulating barrier, outside described polyfluorinated ethylene insulating barrier, wrap up one deck chloroprene rubber sheath layer.

Described control cable core inside is extruded with 52 groups of nickel conductor cable cores.

The utlity model has in sum following beneficial effect: the utility model is widely used in the fields such as chemical petroleum, electric power, has good acid-proof alkaline and good shielding properties, also have simultaneously heat-resisting, the advantage that resistance to oxidation and pull resistance are strong.

Wherein: 1, control cable core; 11, nickel conductor cable core; 2, ethylene propylene rubber insulated layer; 3, tinned copper wire armour; 4, nickel strap screen; 5, polyfluorinated ethylene insulating barrier; 6, chloroprene rubber sheath layer.

Embodiment

As shown in Figure 1, a kind of electric power is controlled many conductor thread cores armoured cable, it is by controlling cable core 1, ethylene propylene rubber insulated layer 2, tinned copper wire armour 3, nickel strap screen 4, polyfluorinated ethylene insulating barrier 5 and chloroprene rubber sheath layer 6 form, described control cable core 1 is set to three groups, outside twisting together, wrap up three groups of control cable cores 1 the ethylene propylene rubber insulated layer 2 of one deck, outside described ethylene propylene rubber insulated layer 2, wrap up one deck tinned copper wire armour 3, outside described tinned copper wire armour 3, wrap up one deck nickel strap screen 4, outside described nickel strap screen 4, wrap up one deck polyfluorinated ethylene insulating barrier 5, outside described polyfluorinated ethylene insulating barrier 5, wrap up one deck chloroprene rubber sheath layer 6.

Described control cable core 1 inside is extruded with 52 groups of nickel conductor cable cores 11.

The permission bending radius of this cable is the outside diameter of cable 16 times; Cable permission work maximum temperature is 70 ℃; 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.
