Cast coil transformers are the ideal solution for voltage distribution in harsh environments with airborne dust or high humidity. The windings are vacuum cast inside a solid block of epoxy resin which provides the highest degree of protection to the windings.
These air-cooled low voltage transformers are ideal for power distribution below 600v.
Unit substation dry-type transformers are designed for medium voltage power distribution where liquid-cooling is not an option, such as indoor power distribution line-ups, or outdoor areas with environmental concerns.
