The three-phase high-voltage dry-type transformer is cured by epoxy resin potting process, which is divided into single-phase and three-phase. Its input (primary) voltage is 220V or 380V, and the secondary output high-voltage voltage voltage is generally more than 1000V. It has the advantages of flame retardant, dust-proof, moisture resistance, small partial discharge and good lightning impact resistance. It is widely used in electrical equipment, electrical materials, insulation performance test Dehumidification power supply of high-voltage switchgear, ozone generator, long-distance power transmission, step-up and step-down are used as low-power high-voltage power supply; This series of transformers have the advantages of low loss, small volume, light weight, compact structure, beautiful appearance and convenient use. They can be carefully designed and customized according to customer requirements.
