On the basis of technique scheme, described insulating protection pipe can also be wrapped in the outside of aerial condutor.
On the basis of technique scheme, described composite armor is mixed by insulating material, fire proofing and resin material.
On the basis of technique scheme, described insulating protection pipe is that composite rubber-plastic material or synthetic insulating material are made.
On the basis of technique scheme, described aerial condutor is 1-35kV aerial condutor.
Beneficial effect of the present invention is:
A kind of maintenance pipe for aerial condutor of the present invention, be wrapped in the outside of aerial condutor, wherein, described maintenance pipe comprises insulating protection pipe and composite armor, described insulating protection pipe is wound in the outside of aerial condutor, and is provided with binding between insulating protection pipe and aerial condutor; Described composite armor is wrapped in outside insulating protection pipe.
1, effectively can solve tree and line, contradiction between road, decrease fault, reduce the cost of power department;
2, while reducing the labour intensity of circuit homework personnel, power supply reliability is too increased;
3, anti-wear performance improves, and has permanent ageing resistace;
4, Unit Weight is comparatively light, cross section is less, minimum on conducting wire sag impact;
5, insulation property are strengthened;
6, can have a power failure when circuit homework, the charged installation of energy, coefficient of safety increases;
7, when aerial condutor breakage, the effect of maintenance can be played; When aerial condutor does not have damaged, the effect of protection also can be played;
When 8, constructing after stripping wire external insulation, recover the means variation of insulation.
