Inside the 3D transformer

Engineered down to every component

EMAX 3D distribution transformer

Component 01 / 06

HV Porcelain Bushings

Three high-voltage porcelain bushings rated to 24 kV (Dyn11) feed medium voltage into the wound core.

Our Factory — Pursat Province

Three stages. One uncompromising standard.

From CNC core cutting to final inspection, every transformer is produced and verified in-house across our 40,000 m² facility — Cambodia's first and only transformer plant.

Advanced production — CNC core cutting and automated winding
01

Advanced Production

CNC core cutting, automated winding lines and vacuum-pressure impregnation deliver consistent quality at industrial scale.

Precision testing — impulse and partial discharge testing
02

Precision Testing

Every unit passes routine, type and special tests — including impulse, partial discharge and full-load temperature rise.

Quality control — ISO 9001:2015 inspection stages
03

Quality Control

End-to-end traceability and ISO 9001:2015 processes, governed by an in-house QA team across 14 inspection stages.
