Epoxy resin cast dry-type transformer

Product Features：

    The SC(B)12(13,14,18) power transformers produced by us are low-noise, low-loss and resin    cast coil dry-type transformers with product model certificates issued earlier in China. With  advanced design, high-quality materials, scientific formula, strict process and high-standard  testing, the products have the following characteristics:

1. The HV winding is wound with copper wire, and the LV winding is wound with copper wire or copper foil. DMD is filled and wrapped. Under vacuum state, it is cast with epoxy resin without filler. After curing, a solid oblong shape is formed, with high mechanical strength, small partial discharge and high reliability.
2. They are flame retardant, explosion-proof and environmentally friendly. Insulating  materials such as DMD have self- extinguishing characteristics and will not generate arc due to short circuit, and the resin will not produce toxic and harmful gases under high heat.
3. The coil does not absorb moisture, and the core clamp has a special anti-corrosion  protective layer. The products can operate in 98% relative humidity and other harsh  environments, without the need of dehumidification treatment for intermittent operation.
4. They have high resistance to short circuit and lightning impulse.
5. The resin layer inside and outside the coil is thin and has good heat dissipation  performance. Natural air cooling (AN) is generally adopted. Transformers of any IP grade  can be equipped with an air cooling system (AF) to improve the short-time overload capacity and ensure safe operation.
6. They realize low loss, good power saving effect, economical operation and free maintenance.
7. They are characterized by small size, light weight, less occupied space, and low installation cost. There is no need to consider oi discharge tank, fire prevention facilities and standby power supply.
