Brief description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of tension anti-torsion power cable, including cable inner support insulation vallum 1, cable conductor 2,
Triangle insulation filling cavity 3, nylon strengthen rope 4, insulation chip pressing layer 5, fire-resistant isinglass belt 6, dacron thread braiding layer 7, shielding
Layer 8, sheathed structure layer 9 and wearing layer 10, three 2 cores of cable conductor uniformly lie along triangle insulation filling cavity 3
Inside, and be separated from each other and extended in parallel by the cable inner support insulation vallum 1 at its center between three cable conductors 2；
The insulation chip pressing layer 5 encloses round pressing and forming around triangle insulation filling cavity 3, and the inside of chip pressing layer 5 filling of insulating
It is provided with three nylon and strengthens rope 4, and the nylon strengthens rope 4 and is bonded setting with the lateral wall of triangle insulation filling cavity 3；Institute
State 5 outer layer covers of insulation chip pressing layer and be provided with fire-resistant isinglass belt 6, the periphery parcel of the fire-resistant isinglass belt 6, which is provided with, to be washed
Synthetic fibre silk braiding layer 7, the periphery parcel of the dacron thread braiding layer 7 are provided with shielded layer 8, and the periphery parcel of the shielded layer 8 is set
Sheathed structure layer 9 is equipped with, the periphery parcel of the sheathed structure layer 9 is provided with wearing layer 10.
The anti-draw properties of whole cable are realized around the nylon reinforcement rope 4 of triangle insulation filling cavity 3 by three rhizospheres；
And due to the shape of triangle insulation filling cavity 3 so that its internal structure can pass through when cable is subject to traction action power
Nylon strengthens rope 4 itself and nylon strengthens being bonded interaction between rope 4 and triangle insulation filling cavity 3 so that active force delays
Solution acts on the internal structure of triangle insulation filling cavity 3.
Further, the shielded layer 8 weaves for steel wire and wraps up setting and forms.
Further, the cable inner support insulation vallum 1 includes middle insulated nylon rope and insulation pillar construction, institute
The one end for stating insulation pillar construction supports setting, the other end of the insulation pillar construction around middle insulated nylon rope active force
Set with 2 supporting force of cable conductor.The design of the structure, and the structural union cable conductor 2 and triangle insulation filling
3 joint mitigation of cavity, can effectively realize the torsional amplitude and twisting resistance for alleviating cable conductor 2.
To sum up：The utility model power cable possesses superior anti-draw properties and anti-torsion performance, is provided simultaneously with good
Fire prevention, shielding, wear-resisting durable effect.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
