The 35kV non-excited disk tap-changer is an important component to ensure the stability and efficiency of the power distribution network. Thanks to advanced technology and robust construction, the tap-changer is able to seamlessly regulate voltage levels to meet the dynamic needs of the grid. This provides consumers with smooth, uninterrupted power supply even during peak loads.
One of the main features of this tap changer is its tank hole Φ43, which makes it easy to install and maintain. The large water tank hole provides ample space for access and repair of internal components, making it easy for technicians to perform inspections and repairs. This design also effectively cools the tap changer, ensuring optimal performance and longevity.
