Product Description

Our three-phase oil-immersed small substation transformer is designed for power distribution systems. Substations are critical components that generate, transmit, and distribute electricity, converting voltage levels between high transmission and low distribution voltages. These units are built to connect separate transmission voltages efficiently and reliably.

Key Features:
  • High capacity for industrial and commercial use
  • High energy conversion efficiency
  • Multiple cooling: Oil-immersed, Air-cooled
  • Advanced insulation materials
  • Overload & short-circuit protection
  • Fully customizable input/output voltages
