Product Description

PURANA insist on the best material, latest APG technology and highest standard production control, which can make sure that our embedded poles can reach the highest quality:

1. Innovative APG casting can prevent effects shock, moisture and dust on the interrupter;
2. China best vacuum interrupter manufacturer, also it can be designated by clients;
3. All Germany imported epoxy resin, it has good cracking resistance characteristic and glass transition temperature can reach 110ºC;
4. Choosing the T2 cooper, shaped by the forging and pressing, then the upper and lower outgoing terminals has good inner compactness and conductivity;
5. All Germany imported glass fiber has excellent shock resistance and tensile strength make sure the best quality of embedded pole.

Definition:

Embedding the vacuum interrupter in a special cast resin makes the pole parts of the circuit-breaker notably robust and at the same time protects the vacuum interrupter from impact, dust, moisture and external damage. PURANA insist on the best material, latest APG technology and highest standard production control, which can make sure that our embedded poles can reach the highest quality. Maintenance-free for life, modular in structure and extremely robust and compact in design - characteristics enabling embedded poles for vacuum circuit breakers to fulfill the highest quality standards and making them highly reliable even in adverse conditions. With their intelligent overall design, the embedded poles can easily be assembled into vacuum circuit-breakers, making them the optimum choice for apparatus manufacturers. As a further plus, embedded poles function is absolutely stable in the widest conceivable range of climatic conditions.
