Features
1. The high-voltage winding is made of enameled copper wire, and the low-voltage winding is made of copper foil. The high-voltage winding is filled with glass fiber felt. Under vacuum state, it is cast with imported epoxy resin without filler. After curing, it forms a solid whole with high mechanical strength, less partial discharge and high reliability.
2. Flame retardant, explosion-proof, non-polluting environment, environmental protection type, can be installed in the load base.
3. The coil does not absorb moisture, the iron core, and the clips can be operated in 100% relative humidity and other harsh environments after being processed by special processes. Intermittent operation does not require dehumidification treatment.
4. High level of short circuit resistance, lightning impact and strong overload capacity.
5. The resin insulation layer inside and outside the coil is thin, and the heat dissipation performance is good. An air cooling system (AF) can be configured for transformers of any protection level.
6. Low loss and high power saving effect. Economical operation and maintenance-free.
7. Small size, light weight, small floor space and easy installation.
8. As a new generation of dry-type transformers, SC (B) dry-type transformers are suitable for power supply in the following places; high-rise buildings, theaters, industrial and mining enterprises, offshore oil rigs, ships, subways, stations, airports, power plants , Residential quarters and high-rise buildings, etc .;
