Contact us immediately for exclusive selection guidance, technical support, and factory direct pricing!

The SARAH Electric advanced 110KV power transformer is designed specifically for high-voltage transmission and distribution networks, suitable for AC systems with a rated voltage of 110KV and a frequency of 50Hz. It can achieve efficient transmission and distribution of electrical energy from the power generation end to the user end. Convert 110KV high voltage electricity into medium voltage levels such as 35KV and 10KV to meet different load requirements. It supports stable power supply for complex loads in multiple scenarios such as industrial, commercial, and infrastructure.

110KV Power Transformer


Advantage

1. The intelligent transformer adopts high permeability oriented silicon steel sheets and optimized winding structure, reducing no-load loss by more than 30% compared to traditional models, meeting the national first level energy efficiency standard. Long term operation can significantly reduce electricity costs.

2. It can operate stably in extreme environments ranging from -40 ℃ to+45 ℃, and is suitable for special climate areas such as high cold, high temperature, and coastal areas.

3. By optimizing magnetic flux distribution and designing vibration reduction structures, the operating noise is reduced by 10dB compared to national standards, meeting the environmental requirements of urban substations and ensuring that you will not be prohibited from using it after purchase!

4. Global certification compliance, products have passed international and national standard certifications such as ISO9001, ISO14001, IEC60076, GB1094, etc., supporting exports to global markets.

Application scenarios

1. The 110kV power transformer serves as the main transformer for 110KV/35KV or 110KV/10KV, responsible for the distribution of electrical energy in the regional power grid.

2. Anti short circuit transformers provide high-voltage input voltage reduction for high energy consuming industries such as steel, chemical, and cement, supporting the smooth operation of high-power equipment such as electric arc furnaces and rolling mills.

3. As a step-up transformer in wind farms and photovoltaic power stations, it can increase the voltage from 690V/10KV to 110KV and integrate it into the main grid to improve power generation efficiency.

4. Oil immersed transformers are used in traction substations to provide stable traction power for high-speed trains and subways.


FAQ

1. What should be paid attention to in the daily maintenance of 110KV transformers?

A: The fully sealed model only requires regular checks of oil level, oil temperature, and sleeve cleanliness; The intelligent monitoring model can view real-time data such as insulation oil color spectrum and winding temperature through the backend system.


2. How to reduce the no-load loss of transformers?

A: We suggest choosing high magnetic conductivity silicon steel sheets, optimizing the iron core joint process, and adopting a three-dimensional coiled iron core structure, which can effectively reduce no-load losses by 30% to 50%.


3. Can 110KV power transformers be used in high-altitude areas?

A: Sure, but the design needs to be adjusted according to the altitude (insulation level increases by 10% for every 1000 meters) to ensure that the electrical clearance and creepage distance meet the standards.
