The advanced epoxy resin casting technology is applied in the transformer, which has excellent short-circuit withstand capability, thermal stability, and reliability. It is 30~160KVA 200~800KVA 1000~2500KVA rated. It has high operating efficiency, compact structure, and quiet operation. The product is widely used in applications with strict requirements for firefighting and explosive protection.

Main features:

Epoxy resin insulation:
The transformer adopts epoxy resin casting coil to achieve excellent electrical insulation performance and high reliability in adverse environments. EI type dry structure, no requirement for using lubricating oil, is environmentally friendly and safe, and can be used in sensitive environments.

High efficiency:
Efficiency >98%, extremely low energy loss during operation, economical and environmentally friendly.

Advanced cooling technology:
AN/AF cooling method ensures efficient heat dissipation, so that the transformer always operates at the optimum temperature.

Customized Output Voltage:
The output voltage can be tailored to suit your specific needs, including standard options such as 220V, 380V, 440V and 480V.

Good Short Circuit Withstanding:
Thanks to its high mechanical strength and solid construction, this transformer is able to withstand short circuit conditions, with enhanced durability and reliability.

Dry Design:
The dry design carries no risk of oil leakage, and the fire-resistant epoxy material makes it ideal for use in fire-prone areas.

Long Service Life:
The transformer is constructed to last long with minimal maintenance requirements and thus reduces operating costs.
