Cast Resin Transformers

Cast Resin Transformers

Cast Resin Transformers are the popular power transformer choice for high-service reliability. GNEE's cast resin transformers are dry-type transformers (CEI EN 60076-11). The magnetic circuit and windings are not immersed in an insulating liquid but are cast with an epoxy resin mixture.

Cast epoxy resin transformers are highest on the evolutionary scale of transformer design and offer the best combination of electrical and mechanical performance factors. The robust structure achieved by casting the windings in a solid shell of epoxy provides mechanical strength unsurpassed by any other transformer available on the market. Cast resin transformers offer safety, environmental and sustainability goals set forth by many industries.

Cast resin transformers are a popular choice for use in commercial, industrial and residential sites. These power tranformers require practically no maintenance and have a much lower environmental impact than traditional oil-immersed transformers. Auto-extinguishing and other safety features make it the obvious choice for indoor applications and other areas with high fire risk.
