Dry Type Transformer
application Details
Dry-type transformer is a high-voltage power distribution equipment that uses solid insulation (such as epoxy resin) instead of traditional transformer oil. It has the advantages of fire prevention, explosion prevention, environmental protection, and low loss. It is suitable for power systems in industry, commerce, new energy and special environments.
Rated voltage: 20kV (or 22kV) high voltage side, 400V/690V low voltage side
Capacity range: usually 100kVA~5000kVA, larger capacity can be customized
Short circuit impedance: 6%~8% (standard value, adjustable according to demand)
Temperature rise limit: ≤100K (F class insulation) or ≤125K (H class insulation)
Noise level: ≤55dB (natural cooling) or ≤65dB (forced air cooling)
