Product Overview
110-132kV High-Voltage Oil-Immersed Transformer from a Leading Chinese Manufacturer
The oil-immersed distribution transformers of the 110-132 kV voltage class have attained a standardized structure through the transformation of Type 9 to Type 10, Type 11, and Type 13. The transformers are designed with self-cooling and air-cooling mechanism to be used for the transmission and distribution process of regional power grids, industrial production, and urban power supply.
Applications & circuit protection
This transformer is perfect for regional grid transmission and urban/construction supply applications where there is a need for high voltage and high power transformation.
- Regional grids comprise the transmission and distribution links.
- Industrial energy includes oil fields, coal mines, and parks.
- Urban power refers to the power supplied to cities and other infrastructures.
- Transport infrastructure/intelligent hubs makes provision for railway stations and airports.
Construction & operating reliability
With its standardized design featuring improved short-circuit resistance and heating control, it ensures reliable and low-loss operation even under the toughest high-voltage conditions.
- Standardized solution for voltages from 110 to 132 kV
- Options from types 10,11,13
- Self-cooling and air-cooling structures
- Improved short-circuit resistance
- Reliability for regional grids and industries

Transformer Wiring & Connection
The High Voltage Oil Immersed Transformer has terminals that are marked HV terminal and LV terminal. Different connection group arrangements like Yyn0 and Dyn11 depict how the transformer is connected into a power grid network. In medium-voltage, normal bushing of the transformer box set hardware makes possible to connect the transformer with the output line providing full connection scheme and terminal layout.
- Marking of HV and LV terminals according to standards IEC/GB
- It is possible to connect the transformer with the grid according to specification of termination type Dyn11 and Yyn0.
- The connection diagram and terminal overview come along with the unit.

Export Markets & Country Compatibility
The High-Voltage Oil-Immersed Transformer is shipped to markets including Southeast Asia, the Middle East, Africa, Latin America, South Asia and Europe. 50 Hz units fit general international networks, while 60 Hz variations can be made for markets like North America and parts of the Middle East. Voltage combinations can meet all requirements for each receiving country.
Transformer Dimensions, Weight & Packing
The weight and sizes depend on the capacity, voltage and type. Generally, distribution ratings have the following approximate values: the dimensions of a 100 kVA oil-immersed unit are 1000-1200 mm in length, 500-700 mm in depth and 1100-1400 mm in height, and its weight is about 600-900 kg. All larger ratings can be scaled accordingly. It is agreed upon in the order that the complete drawings and weights will be provided as well as prepare the unit for shipping.
