OIL-IMMERSED TRANSFORMER

New Products / New Technology

Oil-immersed transformers are high-voltage, large-capacity power transformers that use transformer oil for insulation and heat dissipation. They serve as core equipment in transmission grids and power plant step-up stations. The product range includes two-winding, three-winding and autotransformers, widely used for voltage step-up, step-down and power allocation between different voltage levels. Featuring reliable insulation, low partial discharge, low noise and strong overload capacity, they are suitable for long-term continuous operation and complex operating conditions, providing efficient and stable power transformation solutions for power and infrastructure projects worldwide.

ON-LOAD TAP CHANGING RECTIFIER TRANSFORMER

New Products / New Technology

On-load tap-changing rectifier transformers are specially designed for rectifier loads, enabling voltage regulation under load without interruption. The unit comprises a core, grid-side winding, multi-valve-side windings, an on-load tap-changer and a cooling system, supporting 6-pulse to 24-pulse rectification with effective harmonic suppression. Cooling modes include ONAN, ONAF, OFAF and dry-type AN/AF. Widely used in electrolytic aluminum, electrolytic zinc, electrolytic copper, ion-exchange membrane electrolysis, hydrogen production by electrolysis, silicon carbide and carbon anode materials, the products feature high short-circuit withstand capability, low loss, low noise and intelligent online monitoring, providing stable and controllable AC input for rectifiers.

MOBILE TRANSFORMER

New Products / New Technology

Vehicle-mounted mobile transformers are complete emergency power supply units integrated onto transport vehicles, featuring high mobility and rapid deployment for sudden outages, disaster relief, temporary power demand and grid maintenance. The unit integrates the transformer, HV/LV switchgear, protection and control system, and cable connection system into one package, with anti-vibration and dust-proof design suitable for complex roads and harsh environments. It supports plug-and-play operation, greatly reducing outage time and ensuring uninterrupted power for critical loads. Widely used in urban emergency response, rescue operations, major event power supply, mining and remote area temporary power, it is an important part of modern grid emergency support systems.
