Product Introduction
110kV three-phase oil-immersed power transformer is manufactured in conformity with
IEC60076 standards (applicable International Electrotechnical Commission standards)
and GB1094 standards (applicable state standards of the People's Republic of China).
This series of transformers features excellent impact resistance, high mechanical strength,
strong short circuit resistance, low partial discharge, low noise, nice sealing performance
and less maintenance. It is widely used as the main transformer in power stations,
transformer substations and power transmission and transformation systems of urban
and rural power grids.

Main functions and features
1. 110kV class Main transformers, used company-specific computing procedures, the
transformer core, coil, body, lead, fuel tank and other components for a comprehensive
design to ensure product performance.
2. S11~S13 series product in the S9 series based on average reduced 30% no-load loss
than idle current S9 70%-85% will. Long service life/
Transformer tank adopts full seal structure, the tank along with box available bolt connection
or welding die, transformer oil not contact with air and prolong the life.
3. Running high reliability/ Tank sealing parts were concerned, increased reliability
improvements to ensure and improve technology leveloff reliability of sealing.
Field area is small.
