THE PROCESS

From core to tested unit, in-house.

/ 01

Coil winding

High- and low-voltage automatic winding machines produce precision windings.

/ 02

Foil winding

Foil-wound coils for dry-type and low-voltage applications.

/ 03

Vacuum casting

Epoxy cast-resin bodies with a vacuum pouring chamber.

/ 04

Vapour phase drying

Vapour-phase drying of the core and coil assembly.

/ 05

Vacuum oil filling

Vacuum oil filling for liquid-immersed transformers.

/ 06

Core & assembly

Automatic steel-core shearing line, robot stacking and final assembly.

TESTING

Type-tested, accredited in-house.

Three test bays — cast-resin dry-type, liquid-immersed power and substation — run routine, type and special tests. The test centre is accredited by CNAS (ISO/IEC 17025) and includes 110 kV-grade testing capability.

STANDARDS

Built to international codes.

Manufactured and type-tested to UL, CSA, IEEE, IEC, CE, ASTA and DEKRA requirements, and listed with D-U-N-S.

  • UL — Underwriters Laboratories
  • CSA — CSA Group
  • IEEE — Institute of Electrical and Electronics Engineers
  • IEC — International Electrotechnical Commission
  • DEKRA
  • Intertek / ASTA
