Description
Technical field
The utility model relates to military industry equipment field more particularly to a kind of cold-resistant flexibility military project cables.
Background technique
Since the temperature difference of different regions is larger, there are many area, temperature is lower throughout the year, and existing cable cannot expire
The requirement of sufficient low temp area, existing cold resistant cable is also just with the greatest limit of common material, such cable
Although can use in low temp area, the service life of product is relatively short, and is difficult to be bent in use process, is easy out
Rhegma is bad, does not have insulating layer inside existing cable, not can be well protected cable.Therefore, the utility model proposes a kind of resistance to
Cold flexibility military project cable.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of cold-resistant flexibility military project cable, the cold-resistant flexibility military project electricity
The inside of cable is equipped with supporting layer, so that cable also has good flexibility at low ambient temperatures, extends cable in low temperature ring
Service life under border, supporting layer inside are equipped with rubber grain, and can be very good protection cable will not be extruded damage, insulating layer
Setting so that cable is also with good performance at low ambient temperatures, the setting for the conductor shield that resists cold can be mentioned preferably
The electrical property of high conductive surface allows to provide bigger electric power.
To solve the above problems, the utility model provides a kind of cold-resistant flexibility military project cable, including conductor, cold-resistant lead
Body shielded layer, cold-resistant insulation layer, the outside of the conductor is equipped with cold-resistant conductor shield, and sets on the outside of cold-resistant conductor shield
There is cold-resistant insulation layer, the outside of the cold-resistant insulation layer is equipped with cold-resistant protective layer, and the outside of cold-resistant protective layer is equipped with insulating layer,
The outside of the insulating layer is equipped with supporting layer, and the outside of the supporting layer is equipped with cold-resistant protection jacket layer.
Further improvement lies in that: the conductor is twisted to be led by more plain conductors according to what same direction was twisted
Body.
Further improvement lies in that: the cold conductor shield is woven using tin plating soft copper silk.
Further improvement lies in that the cold-resistant insulation layer uses cold-resistant PVC mixing material or cold-resistant bottom cigarette halogen-free material system
At.
Further improvement lies in that: the inside of the insulating layer is filled with heat preserving and insulating material.
Further improvement lies in that: the inside of the supporting layer is equipped with wavy rubber buffer strip.
Further improvement lies in that: rubber grain is filled with inside the supporting layer.
The utility model has the following beneficial effects: this resists cold soft the utility model proposes a kind of cold-resistant flexibility military project cable
The inside of toughness military project cable is equipped with supporting layer, so that cable also has good flexibility at low ambient temperatures, extends electricity
The service life of cable at low ambient temperatures, supporting layer inside are equipped with rubber grain, and can be very good protection cable will not be extruded
Damage, the setting of insulating layer, so that cable is also with good performance at low ambient temperatures, the setting for the conductor shield that resists cold,
The electrical property that conductive surface can preferably be improved allows to provide bigger electric power.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is further described below in conjunction with embodiment,
The present embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
According to Fig. 1,2,3, a kind of cold-resistant flexibility military project cable is present embodiments provided, including conductor 1, cold-resistant lead
Body shielded layer 2, cold-resistant insulation layer 3, the outside of the conductor 1 are equipped with cold-resistant conductor shield 2, and the conductor shield 2 that resists cold
Outside is equipped with cold-resistant insulation layer 3, and the outside of the cold-resistant insulation layer 3 is equipped with cold-resistant protective layer 4, and the outside of cold-resistant protective layer 4
Equipped with insulating layer 5, the outside of the insulating layer 5 is equipped with supporting layer 6, and the outside of the supporting layer 6 is equipped with cold-resistant protection jacket layer 7,
The conductor 1 is the stranded conductor being twisted by more plain conductors according to same direction, and the cold conductor shield 2 uses
Tin plating soft copper silk weaves, and the cold-resistant insulation layer 3 uses cold-resistant PVC mixing material or cold-resistant bottom cigarette halogen-free material system
At, the inside of the insulating layer 5 is filled with heat preserving and insulating material, and the inside of the supporting layer 6 is equipped with wavy rubber buffer strip,
Rubber grain is filled with inside the supporting layer 6.
The utility model has the advantages that the inside of the cold-resistant flexibility military project cable is equipped with supporting layer 6, so that cable is at low ambient temperatures
With good flexibility, the service life of cable at low ambient temperatures is extended, is equipped with rubber grain inside supporting layer 6, it can
