Product description

  1. Both the HV and LV windings are surrounded and filled by glass fiber mats, no filler in epoxy resin during casting under vacuum condition. The windings will be solid cylindrical overall, with high mechanical strength and high reliability and no partial discharge.
  2. Fire and explosion proof, do not pollute the environment. Coil winding insulation materials such as glass fiber with self-extinguishing properties, and will not arcing when short-circuit happened; heat the resin will not produce toxic of harmful gases.
  3. Coil does not absorb moisture, core clamps have a special corrosion protection layer, and transformers can be abnormally running in the 93% relative humidity condition. No need special treatment during intermittent service.
  4. High short circuit withstanding capability lightning impulse level.
  5. Thin resin in both inner and outer of coil can ensure good heat dissipation. Normally the transformer is air cooling type(AN). Force air cooling type(AF) can be used on any transformer, in order to improve short-term overload capacity, to ensure safety operation.
  6. Lower loss level are reduce the running cost , and all transformers are maintenance-free.
  7. Small size, light weight, small floor space, low cost of installation, no need to consider the discharge of oil, fire and other fire control facilities and stand by power.
  8. Because there is no fire and explosion possibility, it can be easily installed in any place of load center and fully close to the power consumption equipment, thus reducing the loss on the transmission line.
  9. Good performance on heat resistance and anti-aging.
  10. 10.Key technology parameters are in good balance, the load is well-distributed, which is reduces the amount of non-characteristic harmonic wave effectively .
