Abstract

A military movable control cable is characterized in that a conductor is stranded by a plurality of tin-plated brass wires; the conductor is extruded and wrapped by an insulated layer of irradiation-crosslinkable poly (ethylene/tetrafluoroethylene) ETFE, thus forming an insulated wire core; a plurality of insulated wire cores are stranded to prepare a cable and a high-modulus fiber yarn rope filling layer is arranged in the cable, thus forming a cable core; a polytetrafluor ethylene film belt layer and a tin-plated brass wire knitted shielding layer are sequentially wrapped on the outside part of the cable core; a plurality of drainage wires stranded by tin-plated brass wires are arranged between the polytetrafluor ethylene film belt layer and the tin-plated brass wire knitted shielding layer; and the outside part of the shielding layer is extruded and wrapped by a sheath layer which takes a thermoplastic vulcanized rubber as the material. In the utility model, the military movable control cable has the advantages of good flexibility, cold resistance, light weight and the like, and has the mechanical performances such as interference resistance, tension resistance, bending resistance, distortion resistance and the like, thus meeting the requirement of field operation in severe environments.

Description

A kind of military mobile model control cable

Technical field

The utility model relates to the electrical equipment control cable, relates in particular to a kind of military mobile model control cable, belongs to technical field of electric wires and cables.

Background technology

For mostly being the open-air field cable that uses and the cable of other similar applications, require to have good electric property, favorable mechanical physical property, good cold tolerance, and in light weight; Simultaneously, for satisfying the needs of wild environment operation, also require cable stretching resistance, counter-bending, antitorque commentaries on classics.

The performance of cable mainly is the embodiment that constitutes its material property, and still, the conventional at present cable material that uses is difficult to satisfy its comprehensive performance requirement.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, and a kind of softness, cold-resistant, in light weight is provided, can be anti-interference, stretching resistance, counter-bending and antitorque commentaries on classics, can satisfy the military mobile model control cable of field work adverse circumstances.

The utility model adopts following technical scheme:

The design feature of the military mobile model control cable of the utility model is that conductor is the many stranded formations of tinned copper wire, extrudes irradiation crosslinking type ethylene-tetrafluoroethylene copolymer ETFE insulating barrier and constitute insulated wire cores on conductor; By the stranded stranding of many eradications edge core and high modulus fiber yarn rope packed layer is set constitutes cable conductor; Outside cable core, set gradually wrapped polytetrafluoroethylene film belt and tinned copper wire woven shield; The many stranded drainage threads that form of tinned copper wire are set between polytetrafluoroethylene film belt and screen, and extruding with thermoplastic's hard rubber material outside screen is the restrictive coating of material.

The design feature of the military mobile model control cable of the utility model also is:

Described conductor adopts performance index to meet the 5th kind or the 6th kind of flexible conductor material of GB/T3956-2008;

Described conductor adopts regular lay configuration.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model conductor adopts the tin-coated copper twisted wire, and the protection copper conductor guarantees the fail safe of cable conductor in manufacture process and not oxidized under the normal operating position;

2, the utility model insulating layer material adopts ethylene-tetrafluoroethylene copolymer ETFE, has good electric property, favorable mechanical physical property, good cold resistance, and its density makes cable weight lighter for a short time;

3, the utility model screen is adopted the tinned copper wire braiding, prevents the influence of cable external electromagnetic field to cable, and this structure has guaranteed that the flexibility of cable is not subjected to too much influence, cable is moved under field condition flexibly use;

4, external sheath layer adopts thermoplastic vulcanizates rubber material in the utility model, and it has requirements such as good cold-resistant and flexibility, in light weight, favorable mechanical physical property, density are little, also takes into account the stretching resistance of cable, counter-bending and antitorque commentaries on classics performance simultaneously.Aspect processing, do not need special equipment and vulcanization process, production efficiency height, small investment, low cost and other advantages;

5, the utility model conductor adopts multiply tin-coated copper lay configuration, and control twisted wire pitch, makes conductor and cable have flexibility preferably.
