As preferably of the present utility model, described conflict stiff dough is provided with the clamping ring for fastening soft of described connection on adjacent described monomer, and described clamping ring is gathered to cable axis gradually by away from described conflict stiff dough direction.
The tension force utilizing the metal ductility of described clamping ring to be formed fastens soft of described connection, avoids the trouble using fixture and connector, reduces the cost that poling cable is exempted from this kind of resistance to compression further.
As preferably of the present utility model, the minimum range that described clamping ring exempts from poling cable axis to this kind of resistance to compression is less than the ultimate range that poling cable axis is exempted from described connection soft to this kind resistance to compression, and described clamping ring is less than to the ultimate range that poling cable axis is exempted from this kind of resistance to compression poling cable axis to be exempted from by described conflict stiff dough ultimate range to this kind of resistance to compression.
As preferably of the present utility model, soft of described connection is provided with stays groove.
In sum, the utility model has following beneficial effect:
1, poling cable outermost layer is exempted from this kind of resistance to compression is described armour, and described armour comprises multiple monomer be connected to each other, and namely ensure that radial structural strength, in turn ensure that bending flexibility.
What 2, poling cable was exempted from this kind of resistance to compression comprises flame-retardant layer and Halogen layer, promotes the useful life of cable.
3, described monomer comprises conflict stiff dough and is connected soft, promotes practicality further.
4, described clamping ring and the described connection being connected soft are without the need to fixture and connector, and plug is convenient, and it is convenient to connect.
