Abstract

The utility model discloses a power cable. The power cable is formed by conductor groups, a filling layer, an ethylene propylene rubber insulation layer, a galvanized steel wire armored layer, a copper strip shielding layer, an aluminum strip armored layer and a chloroprene rubber sheath layer. There are three conductor groups which are extruded in the filling layer. One ethylene propylene rubber insulation layer wraps the filling layer. One galvanized steel wire armored layer wraps the ethylene propylene rubber insulation layer. One copper strip shielding layer wraps the galvanized steel wire armored layer. One aluminum strip armored layer wraps the copper strip shielding layer. One chloroprene rubber sheath layer wraps the aluminum strip armored layer. The cable can be widely used and the service life is long. 4 million times of circular bending can be performed on the cable. The cable possesses high tensile performance and is firm, durable and practical. The cable possesses oil resistant performance, corrosion resistant performance and high inoxidizability performance and can be widely used in electric power production, metallurgy manufacturing and petrochemical industry fields.

Description

A kind of power cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of power cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as electrical production, metallurgical manufacture and field of petrochemical industry in the cable that uses, all high especially to the requirement of the oil resistant of cable, corrosion-resistant, non-oxidizability and chemical resistance aspect.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide that a kind of pull resistance is strong, long service life and the good power cable of chemical-resistance.

The utility model takes following technical scheme to realize: a kind of power cable, it is by conductor group, packed layer, ethylene propylene rubber insulated layer, zinc-coated wire armour, copper strip shielding layer, aluminium strip armour and chloroprene rubber sheath layer form, described conductor group has three groups, be extruded in packed layer inside, described packed layer is wrapped with the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, wrap up one deck zinc-coated wire armour, outside described zinc-coated wire armour, wrap up one deck copper strips screen, outside described copper strip shielding layer, wrap up one deck aluminium strip armour, outside described aluminium strip armour, wrap up one deck chloroprene rubber sheath layer.

Described conductor group by three aluminium conductors, be wrapped in three belting layer and butyronitrile insulating barriers outside aluminium conductor and form.

The utlity model has in sum following beneficial effect: the utility model is of many uses, long service life, can experience reversed bending reaches 4,000,000 times, there is pull resistance strong, the feature of firm durable practicality, also there is oil resistant, the feature that corrosion-resistant and non-oxidizability is strong, be widely used in electrical production, metallurgical manufacture and petrochemical industry.

Wherein: 1, conductor group; 2, packed layer; 3, ethylene propylene rubber insulated layer; 4, zinc-coated wire armour; 5, copper strip shielding layer; 6, aluminium strip armour; 7, chloroprene rubber sheath layer.

Embodiment

As shown in Figure 1, a kind of power cable, it is by conductor group 1, packed layer 2, ethylene propylene rubber insulated layer 3, zinc-coated wire armour 4, copper strip shielding layer 5, aluminium strip armour 6 and chloroprene rubber sheath layer 7 form, described conductor group 1 has three groups, be extruded in packed layer 2 inside, described packed layer 2 is wrapped with the ethylene propylene rubber insulated layer 3 of one deck, outside described ethylene propylene rubber insulated layer 3, wrap up one deck zinc-coated wire armour 4, outside described zinc-coated wire armour 4, wrap up one deck copper strips screen 5, outside described copper strip shielding layer 5, wrap up one deck aluminium strip armour 6, outside described aluminium strip armour 6, wrap up one deck chloroprene rubber sheath layer 7.

Conductor group 1 by three aluminium conductors, be wrapped in three belting layer and butyronitrile insulating barriers outside aluminium conductor and form.

It is 70 ℃ that this cable allows operational environment maximum temperature; Temperature of the end of mounting and installation is-10 ℃; The permission bending radius of this cable is the outside diameter of cable 20 times, can experience reversed bending and reach 4,000,000 times.

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.
