Edge has occurred and that fracture；In conjunction with expanding with heat and contract with cold for aerial condutor itself, and the pillar insulator is increased to a certain extent
The pulling force born.
In addition, the aluminium binding that will be achieved a fixed connection between aerial condutor and pillar insulator, due to friction, unbalance stress
And climatic effect, the case where also often fracture.It can be seen that common pillar insulator cannot be satisfied frame in massif landform
Pulling tension requirements of the hollow wire to insulator.
