Destructive power 5KN of formula insulator.Therefore, it can obtain, when aerial condutor is not also pulled off under external force, the pillar is exhausted
Edge has occurred and that fracture；With reference to expanding with heat and contract with cold for aerial condutor itself, and the pillar insulator is increased to a certain extent
The pulling force for bearing.
In addition, by the aluminum binding achieved a fixed connection between aerial condutor and pillar insulator, due to friction, unbalance stress
And climatic effect, also Jing often occur rupture situation.As can be seen here, common pillar insulator cannot meet frame in massif landform
Pulling tension requirements of the hollow wire to insulator.
