Why buyers choose it

  • A sealed corrugated-fin tank stops oil oxidation and breathing outright, cutting maintenance to a minimum
  • Low no-load loss paired with cool running temperatures keeps efficiency high
  • Engineered for 20–30 years of service, even in tough outdoor settings
  • Flexible across capacity and voltage, with vector groups configured on request
  • Holds IEC, CE, ISO9001/14001/45001, CQC, GOST and EAC certification

Standards & certification

Designed and tested to IEC / GB. Millenium production is certified to ISO 9001, ISO 14001 and ISO 45001; the product family carries CE (ECM), UDEM attestation and an EAC declaration of conformity. Every unit passes routine factory tests before dispatch.

Product details

Available in 160 kVA and 200 kVA ratings, this fully sealed three-phase oil-immersed transformer converts an 11 / 22 kV supply down to 415 V, within a broader lineup that spans 15 kVA to 31500 kVA. The sealed corrugated-fin tank keeps the internal oil free from oxidation and never needs refilling, which is why the unit can deliver 20–30 years of low-maintenance service outdoors or in substation settings. It is offered with copper or aluminium windings and manufactured to IEC and GB standards.

Design & Construction

The steel tank is hermetically sealed and ribbed with corrugated cooling fins, keeping oil separated from the outside air to prevent oxidation and moisture while still radiating heat efficiently. The tank cover carries the high-voltage porcelain bushings and low-voltage terminal connections, and the unit incorporates pressure-relief and oil-level safeguards. Together these elements keep losses low and service calls rare.

Applications

Fits outdoor and indoor distribution needs for utility networks, industrial sites, mining operations, oil-field installations, commercial developments and rural electrification schemes that depend on reliable medium-voltage step-down.

Customisation Options

Capacity, voltage ratio, vector group, winding material (copper or aluminium), tap-changer type (off-load or on-load) and bushing layout can all be tailored to the project's needs.
