Epoxy Resin Cast Dry Type Power Transformer with OLTC

TAILI is a professional manufacturer and supplier of Epoxy Resin Cast Dry Type Power Transformer with OLTC. This product, with high quality and high durability, can bring you benefits:

1. Voltage stability: It can automatically maintain the output voltage within the allowable range, ensuring the normal operation of electrical equipment.
2. Power supply continuity: The voltage regulation process does not require power outage, making it particularly suitable for users with high requirements for power supply continuity (such as data centers, precision manufacturing, hospitals, etc.).
3. Improving grid quality: It can compensate for voltage drops caused by load fluctuations, and is an important means for reactive power compensation and voltage control in the power grid.
4. Flexible and intelligent: It can be connected to an automation system to achieve remote monitoring and automatic control.

Due to these advantages, the transformers are widely used in:

1. Data center: Servers are extremely sensitive to voltage fluctuations.
2. Hospital operating rooms, ICU: Any momentary power outage could endanger life.
3. Semiconductor, LCD panel manufacturing plants: The production process has strict requirements for voltage stability.
4. Financial center: Ensure that the trading system is never interrupted.
5. Important laboratories and research institutions
