DEPTA RIP dry glue paper DC rheological tube
DEPTA RIP dry glue paper DC rheological tube
Product Introduction:
Dc rheo-changing bushing is the main insulation device outside the tank of DC transformer. The lead wire of the winding of DC transformer must pass through the rheo-changing bushing to insulate between the lead wire and the lead wire and the transformer tank, and to fix the lead wire at the same time.
Application scenario:
Mainly used in converter transformer valve side bushing
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.
