  • Offers lower installation costs and minimal maintenance compared to oil-filled transformers.
الأسئلة الشائعة:
  • What environments are these cast coil transformers suitable for?
    These transformers are ideal for harsh environments with airborne dust or high humidity, as the vacuum-cast epoxy resin windings provide superior protection against such conditions.
  • What cooling methods does this 2500kVA transformer support?
    It supports both AN (self-cooled) and AF (forced-air) cooling methods, allowing for flexible operation and optional fan cooling for extra capacity during overloads.
  • Are these transformers compliant with international standards?
    Yes, they are designed, built, and tested in accordance with high industry standards including NEMA, ANSI, DOE, AS60076, and IEEE as applicable.
  • What are the maintenance requirements for a dry-type epoxy resin transformer?
    These transformers require low to no maintenance thanks to their solid cast resin construction, which is self-extinguishing and does not require liquid cooling systems.
