Suspension Clamp
In this issue, the editor introduces ab cable suspension clamp. Friends who want to know relevant knowledge, please come and learn with the editor:
1. Lightning impulse discharge test:
After installing the product according to the use status, check whether the flashover is on the arc-resistant electrode of abc suspension clamp under the action of lightning impulse, and whether the power frequency arc path can be well located.
2. Power frequency arc test:
After the product is installed according to the status, check whether the power frequency follow-up arc root after lightning flashover can be fixed on the arc-resistant electrode, and the degree of arc resistance can not well protect the wire from burns.
3. j hook suspension clamp connection resistance:
After installing suspension clamp for ab cable, the connection resistance shall not be greater than 1.2 times of the wire of the same length.
4. Damage to the wire:
After installing suspension clamp for abc cable, the breaking force of the wire shall not be less than 95% of the specified breaking force of the wire.
5. Flame retardancy of insulation protection:
In the power frequency arc test, the insulation protection should not ignite and expand the burning range.
