Safe and Non-Polluting Three-Phase Step Down Dry Type Power Transformer

Product Description

Safe And Non-polluting Three-Phase Step Down  Dry Type Power Transformer

Product Description

Resin-insulated dry-type transformers are safe, non-flammable, fireproof, and pollution-free. It can be directly installed in the load center, maintenance-free, easy to install, low overall operating cost, low loss, good moisture-proof performance, can operate normally under 100% humidity, and can be put into operation after shutdown without pre-drying. Low partial discharge, low noise, strong heat dissipation capacity, 120% rated load operation under forced air cooling. Equipped with a complete temperature protection and control system, it provides a reliable guarantee for the safe operation of the transformer with high reliability.

Product features:

Main material and characteristics: Class F coil insulated copper wire as conductor, glass fiber and epoxy resin composite materials for insulation, its coefficient of expansion similar to the copper conductor.with good impact resistance, temperature changes, crack resistance. Glass fiber and epoxy resin constituent all have self-extinguishing, it does not continue to burn, it does not produce toxic gases and pollute the environment.Epoxy resin has good insulating properties, particularly suitable for the production of high-voltage level

Manufacturing process: The winding wound on the high-accuracy winding machine, when winding pave cast grass fibre around the external and internal of the winding, there be armed air passage for transformer of large ca Then dry it in vacuum.The whole casting and solidifying process is performed according to the pi curve of casting control terminal, which transferred through computer network by process department every process can be monitored momentarily and adjusted for the various surroundings. The precise process ensures free bubble and free hole of winding.

1. Safe, not combustible, fireproof can be installed directly in the load center
2. Maintenance-free, easy installation, low economic operation cost
3. Good moisture resistance can operate normally under 100% humidity
4. Low loss, low noise, good insulation, small local discharge, no pollution, loss
5. Good heat dissipation, strong overload capacity, under the condition of air cooling, can overload 50%
6. Reliable operation, with perfect temperature protection control system, can ensure the safe operation of the transformer
7. Small volume, lightweight, stable structure, strong lightning shock resistance, high mechanical strength, temperature change resistance, anti-sudden short circuit ability
