Abstract

The utility model discloses a voltage-stabilization voltage power cable. The voltage-stabilization voltage power cable is composed of an aluminum conductor, an ethylene propylene rubber insulation layer, a chloroprene rubber sheath layer, a copper tape shielding layer, a butyronitrile insulation layer, a galvanized copper wire armoring layer and a copper tape armoring layer, wherein the aluminum conductor is coated with the ethylene propylene rubber insulation layer, the ethylene propylene rubber insulation layer is coated with the chloroprene rubber sheath layer, the chloroprene rubber sheath layer is coated with the copper tape shielding layer, the copper tape shielding layer is coated with the butyronitrile insulation layer, and the butyronitrile insulation layer is coated with the galvanized copper wire armoring layer. The voltage-stabilization voltage power cable of the utility model has the advantages of wide application, long service life, high tensile strength, durability, practicability, strong oil resistance, corrosion resistance and oxidation resistance, and can experience 4000000 times of cyclic bending, and can be widely used in fields of power production, metallurgy manufacture and petrochemical industry.

Description

A kind of regulated power cable

Technical field

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

The utility model takes following technical scheme to realize: a kind of regulated power cable, it is by aluminium conductor, ethylene propylene rubber insulated layer, chloroprene rubber sheath layer, copper strip shielding layer, butyronitrile insulating barrier, zinc-plated copper wire armour and copper strips armour form, described aluminium conductor is seven and wraps up the ethylene propylene rubber insulated layer of one deck outside twisting together, outside described ethylene propylene rubber insulated layer, wrap up one deck chloroprene rubber sheath layer, outside described chloroprene rubber sheath layer, wrap up one deck copper strips screen, outside described copper strip shielding layer, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up the zinc-plated copper wire armour of one deck.

Described copper strip shielding layer inside is extruded with an aluminium wire drainage thread.

Described copper strips armour inside is extruded with a steel wire tensile cord.

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.
