OPTA type oil paper capacitive AC variable bushing

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.

Product features:

Electrical performance

The equimargin method is designed and optimized by computer software. The electric field distribution of casing is more uniform and reasonable, and the insulation performance is excellent.

Automatic winding, variable pressure drying, vacuum oil immersion, low medium loss factor, long-term stable operation.

Mechanical property

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

With high mechanical strength, to meet the requirements of V-class seismic.

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

Operational thermal stability

The product is resistant to high temperature, and the dielectric loss is stable at high temperature.

The current carrying density does not exceed 2A/mm2, and the product temperature rise is low.

Operating environment

Can be used in high altitude areas;

Can be used in heavy dirty areas.
