Cast Resin Power Transformers

Name: China Cast Resin Power Transformers Manufacturers Suppliers Factory - Made in China - GNEE Electric
Brand: GNEE Electric
SKU: 240792838

GNEE provides cast resin transformers with powers up to 30 MVA and voltages up to 52 kV, with no-load or on-load switching. The constructional design used for a power transformers is completely different from that used for distribution transformers. Considerable masses are involved, and during the design stage it is necessary to take into account not just mechanical and electrical issues, but also those related to material expansion during operation.

If you're going to buy customized cast resin power transformers made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

Cast resin power transformers feature primary and secondary windings which are vacuum cast inside a solid block of epoxy resin. The epoxy resin is introduced under vacuum in order to penetrate all the spaces within the winding, ensuring a void free casting with minimal partial discharges. The sold casting provides the highest degree of protection to the windings, making them ideally suitable for harsh environmental conditions which include airborne dust & high humidity. Furthermore, the fiberglass reinforcement which is incorporated into the casting provides the transformer with the highest mechanical strength which makes it resilient to short circuit forces.

Features & Benefits of Cast Coil Power Transformers

Suitable For Harsh Environments - Cast coil transformers offer the greatest degree of protection against the presence of atmospheric pollutants effecting the performance and life expectancy of a power transformer.

High Short Circuit Strength - The fiberglass reinforced solid cast construction provides superior mechanical strength with the highest short circuit withstand capability of all types of transformers.

High Overload Capability - Due to the longer thermal time constant of cast coil transformers, higher short time overload capabilities are possible in comparison with traditional resin impregnated or encapsulated dry type transformers.

Environmentally Friendly - GNEE cast coil transformers contain only chemically non-hazardous materials.

High Impulse Voltage Strength - The impulse voltage withstand capability of cast coil transformers is higher than conventional dry type and is comparable to liquid filled transformers.

Low Maintenance - Cast coil transformers are virtually maintenance free due to their smooth, crevice free construction.
