Product Introduction:

Transformer bushing is the main insulation device outside the transformer and reactor fuel tank, and the lead wire of the transformer winding must pass through the insulation bushing, so that the insulation between the lead wire and the lead wire and the transformer fuel tank are insulated, and it also plays the role of fixing the lead wire.

Application scenario:

Ac transformer, reactor;

Product features:

Electrical performance

The core adopts RIP structure with high insulation heat resistance to avoid long-term aging of insulation materials. Using advanced winding and curing technology, the product discharge is <3pC.

The automatic winding machine is used for winding, and the inner insulation ratio of the core is high, which can effectively improve the distribution of the outer insulation electric field under harsh conditions.

Mechanical property

Double-channel sealing structure, excellent waterproof and leak-proof performance.

With high mechanical strength, meet the requirements of Class Ⅷ earthquake resistance.

The use of high-strength materials to cope with metal fatigue under long-term operation.

Operational thermal stability

No oil, easy to explode, fire and other phenomena after failure, high safety and reliability;

Excellent insulation, maintenance free.

Operating environment

Can be used in high altitude areas;

Can be used in heavy dirty areas.
