Abstract

The invention discloses a tensile cable with an elliptical conductor. The tensile cable comprises three conductor wire cores, two steel wire tensile wires and six outer protection layers. The three conductor wire cores are galvanized nickel conductor wire cores, galvanized aluminum conductor wire cores and galvanized copper conductor wire cores. The two steel wire tensile wires are silver plated steel wire tensile wires, and the six outer protection layers include a nonmagnetic metal armor layer, a silver plated nickel wire shielding layer, a polyvinyl ethylene-propylene insulation layer, a copper strip armor layer, a tetrafluoroethylene-hexafluoropropylene copolymer insulation layer and a silver plated steel strip armor polyethylene sheath layer. The cable has the advantages of being high in conductor stability, good in conductibility, capable of being widely applied to the fields of petrochemical engineering and high in corrosion resistance.

Description

A kind of elliptic conductor tensile cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of elliptic conductor tensile cable.

Background technology

Cable is widely used in every field, relate to people's lives, industrial production every field, but, because the conductors cross of cable inside presents circle more, the stationarity of conductor in cable inside is just not too strong, easy slip, affect the electric conductivity of cable, now, have a kind of cable, the conductors cross of cable arranges and is rendered as elliptical shape, and stability is stronger.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide the elliptic conductor tensile cable that a kind of corrosion resistance is strong and cable conductor steadiness is strong.

The present invention takes following technical scheme to realize: a kind of elliptic conductor tensile cable, it is by three kinds of conductor thread cores, steel wire tension silk and six layers of external protection composition, six layers of external protection are followed successively by nonmagnetic metal armour from inside to outside, silver plated nickel wire screen, polychlorostyrene second propylene insulating barrier, copper strips armour, perfluoroethylene-propylene insulating barrier and silver-plated steel-tape armouring pe sheath layer, three kinds of conductor thread cores are respectively zinc-plated nickel conductor thread core, zinc-plated aluminium conductor core and TC conductor thread core, all be set to four groups, described nonmagnetic metal armour is set to the central core of cable, described zinc-plated nickel conductor thread core is evenly extruded between nonmagnetic metal armour and silver plated nickel wire screen, described zinc-plated aluminium conductor core is evenly extruded between silver plated nickel wire screen and polychlorostyrene second propylene insulating barrier, described TC conductor thread core is evenly extruded between polychlorostyrene second propylene insulating barrier and copper strips armour, described steel wire tension silk is silver-plated steel wire tension silk, be provided with two, evenly be extruded in polychlorostyrene second propylene insulating barrier inner.

Four silver plated nickel wire drainage threads are evenly extruded between described silver plated nickel wire screen and polychlorostyrene second propylene insulating barrier.

The conductor of described zinc-plated nickel conductor thread core, zinc-plated aluminium conductor core and TC conductor thread core inside is all wrapped in the silver-plated nickel of one deck outward and moulds aluminium strip armour.

The present invention has following beneficial effect in sum: this kind of cable has conductor steadiness by force, and the feature that electric conductivity is excellent, can be widely used in field of petrochemical industry, corrosion resistance is strong.
