20KV Dry type transformer

20KV Dry type transformer

  • Dry type transformer

    Dry-type transformers are transformers that do not use liquid cooling. The insulation material is epoxy resin, and the heat is mainly dissipated by air or other gases. They are mainly used in places with high fire protection requirements, such as distribution rooms, and can be equipped with a shell for outdoor use. Due to its environmental protection, safety, and easy maintenance, it is widely used in construction, industry, transportation and other fields.

  • Description
  • Technical specification
  1. Excellent energy-saving effect, economical operation, maintenance-free.
  2. The noise level is reduced, which is 10~15 decibels lower than the current professional standard JB/T10088-2016 "6-220KV transformer sound level".
  3. High mechanical strength, strong short-circuit resistance: Flame retardant, explosion-proof, pollution-free.
  4. Maintenance-free: Good moisture resistance, can operate at 100% humidity, no preheating treatment before commissioning, no dehumidification treatment required for intermittent operation.
  5. Small size, light weight, no cracking, no moire on the surface, low partial discharge.
  6. High insulation level, good lightning impact resistance.
  7. Strong heat dissipation capacity, can operate with rated load under forced air cooling conditions.
