Product Outline Drawing

12kV Insulating Pulling Pole Assembly PRICE

The insulated tie rods are internally fitted with compression springs, which are used to ensure sufficient holding force when the vacuum circuit breaker is closed. This holding force is also used to provide the initial energy for switch opening, related to the rated short circuit current of the switch.

Domestic interrupters are generally referenced to the following table:

Rated short circuit breaking current	Pre-pressure (value of the compression force of the spring after completion of assembly)	Rated voltage (The value of spring compression force after the circuit breaker closes, in accordance with the domestic 3mm over-travel time shall prevail)
25kA	1600±80N	2200±110N
31.5kA	2280±120N	3100±150N
40kA	3370±170N	4500±250N
