Abstract

The utility model discloses a butyronitrile insulation shielded cable which is made of copper conductor wire cores, a butyronitrile insulating layer, an aluminum tape shielding layer and a polyester fiber sheathing layer. The three groups of copper conductor wire cores are extruded in the butyronitrile insulating layer. The butyronitrile insulating layer is coated with the aluminum tape shielding layer. The aluminum tape shielding layer is coated with the polyester fiber sheathing layer. The butyronitrile insulation shielded cable is light in weight, easy to transport, high in waterproofness and long in service life, and also has the characteristics of large bending resistant degree, good flexibility, and excellent oil and mechanical damage resistant performance.

Description

A kind of butyronitrile insulation shielding cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of butyronitrile insulation shielding 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 the cable using in the field such as computer, machine room, high and low temperature resistance to cable, oil resistant, resistance to mechanical damage, light and flexibility aspect require all high especially.

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 long service life, and resistance to flexibility is large, flexible butyronitrile insulation shielding cable.

The utility model takes following technical scheme to realize: a kind of butyronitrile insulation shielding cable, it is made up of copper conductor core, butyronitrile insulating barrier, aluminium strip screen and polyester fiber restrictive coating, described copper conductor core has three groups, be extruded in described butyronitrile insulating barrier inside, outside described butyronitrile insulating barrier, wrap up one deck aluminium strip screen, outside described aluminium strip screen, wrap up one deck polyester fiber restrictive coating.

Described copper conductor core is made up of copper conductor, aluminium strip screen, aluminium strip armour and the aluminum metal flexible pipe that is extruded in aluminium strip armour inside.

Between described three groups of copper conductor cores, be also extruded with a strengthening core.

The utlity model has in sum following beneficial effect: this kind of cable is lightweight, convenient transport, water proofing property is strong, and long service life also has flexibility large, flexible simultaneously, the feature of oil resistant and resistance to mechanical damage function admirable.

Brief description of the drawings

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, copper conductor core; 2, butyronitrile insulating barrier; 3, aluminium strip screen; 4, polyester fiber restrictive coating; 5, strengthening core.

Embodiment
