- Commodity name: Energy Saving Dry Type Transformer Insulation
The safe operation and service life of dry-type transformers largely depend on the safety and reliability of the transformer winding insulation. It is one of the main reasons that the transformer can not work normally because the winding temperature exceeds the insulation withstand temperature and the insulation is damaged. Therefore, the monitoring of the operating temperature of the transformer and its alarm control are very important.

Advantage
1. High insulation strength
Pouring epoxy resin has an insulation breakdown field strength of 18-22KV / mm, and an oil-immersed transformer with the same voltage level has approximately the same lightning impulse strength. The insulation temperature level is F level, and the maximum allowable temperature is 155 ° C. The winding temperature The rise limit is 100K.
2. Flame retardant, explosion-proof, non-pollution, maintenance-free, can be installed in the load center decentrally, reducing investment costs and saving costs.
3. Outstanding disaster prevention performanceEpoxy resin is flame retardant, flame retardant and self-extinguishing, and will not cause secondary disasters such as explosion.
4, Short-circuit resistance, good lightning shock resistance.
5. The shell is made of three materials: stainless steel, cold plate and aluminum alloy. The type is divided into wind type and heat dissipation type. Go in and out.
6. Low operating loss and high operating efficiency
7. Strong overload capacity
When the ambient temperature is 20 ° C, it can be overloaded for 1.16 times in a long time and 1.5 times in 60 minutes. If the fan is put in and the transformer is operated under forced air cooling (AF), it can be overloaded for 1.5 times.
