 1.Company introduction

Liaoning Jinli Electric Power Electrical Appliance Co., Ltd was established in 2001 with a registered capital of 5 million yuan. It is a national high-tech enterprise specializing in the research and development, production, and sales of various types of transformers Tap Changers in China. It is also a national intellectual property advantage enterprise and has a provincial-level enterprise technology center.

The products are mainly sold in more than 20 countries and regions such as South Korea, Russia, Switzerland, Australia, Thailand, India, Peru, etc.

The main export products are No-excitation linear tap changers, Disc type tap changers, and Plate type tap changers, as well as 10~35KV On load tap changer.

2. Product introduction

The immersed off-Load Tap Changer is a device used for operating oil-immersed power transformers under the conditions of de-energization or off-load, to adjust the tap positions of the transformer coil and thereby alter the transformer ratio.

4.Product feature and application

The core function of a tap changer is to adjust the output voltage and ensure grid stability by altering the number of turns in the transformer windings. Its primary applications include:

Substations and Power Distribution: Widely used in substations to finely regulate voltage, thereby maintaining power system stability and ensuring a reliable power supply.

Renewable Energy Systems: In wind and solar power generation, tap changers are utilized to adapt to output fluctuations and maintain grid stability.

Industrial Environments: When large industrial machinery requires specific voltage levels, tap changers ensure smooth operation and prevent interruptions or damage caused by voltage fluctuations.

Categorized Applications: Based on specific needs, they are divided into off-circuit tap changers (suitable for scenarios with stable loads and seasonal voltage regulation, requiring power disconnection for adjustment) and on-load tap changers (suitable for frequent voltage fluctuations and scenarios requiring high power supply continuity, allowing real-time voltage regulation during operation).
