SC (B) 10/11/12/13 10-35KV epoxy resin cast dry-type transformer is safe, flame-retardant and fire-resistant, and can be directly installed in the load center.

Maintenance free, easy to install, low overall operating cost, low loss, good moisture resistance, can operate normally at 100% humidity, and can be put into operation without pre drying after shutdown. Low partial discharge capacity, low noise, strong heat dissipation ability, and can operate at 120% rated load under forced air cooling conditions.

Equipped with a comprehensive temperature protection control system, it provides reliable guarantee for the safe operation of transformers, with high reliability. According to operational research on over 10000 products that have already been put into operation, the reliability indicators of the products have reached an advanced level.

Advantages of dry-type transformers

1. High voltage windings are made of copper wire, low voltage windings are made of copper wire or copper foil, filled and wrapped with glass fiber felt, and poured with unfilled epoxy resin in a vacuum state. After curing, it forms a sturdy circular and rectangular whole with high mechanical strength, low partial discharge, and high reliability.
2. Flame retardant, explosion-proof, and non polluting to the environment. The insulation materials such as glass fiber used for winding coils have self extinguishing properties and will not generate arcs due to short circuits. Under high heat, the resin will not produce toxic or harmful gases.
3. The coil does not absorb moisture, and the iron core clamp has a special anti-corrosion protection layer, which can operate in 100% relative humidity and other harsh environments. Intermittent operation does not require dehumidification treatment.
4. High resistance to short circuits and lightning strikes.
5. The resin layer on the inner and outer sides of the coil is thin and has good heat dissipation performance. Cooling method – usually using natural air cooling (AN). For transformers of any protection level, an air cooling system (AF) can be configured to improve short-term overload capacity and ensure safe operation.
6. Low loss, good energy-saving effect, economical operation, and maintenance free.
7. Small size, light weight, small footprint, low installation cost, no need to consider oil drainage tanks, fire prevention and firefighting facilities, and backup power sources.
8. Due to the absence of fire or explosion hazards, it can be installed in a dispersed manner in the load center, fully close to the power consumption point, thereby reducing the cost of power lines and saving expensive low-voltage facilities.
