Abstract

The invention discloses a flexible armor shielding drainage cable for a motor. The flexible armor shielding drainage cable is composed of grounding cable cores, a tinned nickel wire shielding layer, a butyronitrile insulating layer, a nickel strap armor layer, a copper strap shielding layer and an aluminum strap armor polyethylene sheath layer, wherein the number of the grounding cable cores is four, the four grounding cable cores are wrapped in the tinned nickel wire shielding layer, the tinned nickel wire shielding layer is wrapped in the butyronitrile insulating layer, the butyronitrile insulating layer is wrapped in the nickel strap armor layer, the nickel strap armor layer is wrapped in the copper strap shielding layer, the copper strap shielding layer is wrapped in the aluminum strap armor polyethylene sheath layer, and an aluminum alloy wire drainage wire is further arranged inside the tinned nickel wire shielding layer in an extruding mode. The flexible armor shielding drainage cable is low in installation and laying temperature, has the advantages of being long in service life, resistant to high temperature and flexible, and further has the advantages of being excellent in high-temperature environment electrical stability and electrical conductivity.

Description

Armouring shielding drainage flexible cable for a kind of motor

Technical field

The invention belongs to field of cables, relate in particular to a kind of motor armouring shielding drainage flexible cable.

Background technology

Cable refers to the wire of conduction current, is widely used in every field,, with in the middle of cable the indices of cable is had relatively high expectations at motor, and heat-resisting such as requiring to have, the feature that heat-resisting quantity and electric conductivity are excellent, just can be applied in the middle of motor, ensures safety.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one have heat-resisting, armouring shielding drainage flexible cable for the motor of resistant to elevated temperatures advantage.

The present invention takes following technical scheme to realize: a kind of motor armouring shielding drainage flexible cable, it is made up of ground connection cable core, zinc-plated nickel wire screen, butyronitrile insulating barrier, nickel strap armour, copper strip shielding layer and aluminium strip armouring pe sheath layer.Described ground connection cable core is set to four groups, outside four groups of ground connection cable cores, wrap up the zinc-plated nickel wire screen of one deck, outside described zinc-plated nickel wire screen, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck copper strips screen, outside described copper strip shielding layer, wrap up one deck aluminium strip armouring pe sheath layer, described zinc-plated nickel wire screen inside is also extruded with an aluminum-alloy wire drainage thread.

The present invention has following beneficial effect in sum: this kind of cable installation temperature is low, and long service life has high temperature resistant, soft advantage, also has hot environment electric stability excellent, the feature that electric conductivity is excellent simultaneously.

Brief description of the drawings

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, ground connection cable core; 2, zinc-plated nickel wire screen; 3, butyronitrile insulating barrier; 4, nickel strap armour; 5, copper strip shielding layer; 6, aluminium strip armouring pe sheath layer; 7, aluminum-alloy wire drainage thread.

Embodiment

As shown in Figure 1, armouring shielding drainage flexible cable for a kind of motor, it is made up of ground connection cable core 1, zinc-plated nickel wire screen 2, butyronitrile insulating barrier 3, nickel strap armour 4, copper strip shielding layer 5 and aluminium strip armouring pe sheath layer 6.Described ground connection cable core 1 is set to four groups, outside four groups of ground connection cable cores 1, wrap up the zinc-plated nickel wire screen 2 of one deck, outside described zinc-plated nickel wire screen 2, wrap up one deck butyronitrile insulating barrier 3, outside described butyronitrile insulating barrier 3, wrap up one deck nickel strap armour 4, outside described nickel strap armour 4, wrap up one deck copper strips screen 5, outside described copper strip shielding layer 5, wrap up one deck aluminium strip armouring pe sheath layer 6, described zinc-plated nickel wire screen 2 inside are also extruded with an aluminum-alloy wire drainage thread 7.

The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
