Oil Immersed Voltage Transformer

Our Oil Immersed Voltage Transformer delivers accurate voltage signals for metering and protection. This unit covers voltage levels from 10kV to 252kV. It converts high primary voltages into standard low-voltage signals. These signals feed meters and relays. The transformer uses oil-paper insulation technology. This design offers excellent withstand voltage capability. It also handles overvoltage events effectively. We manufacture this product in our own factory. We have a complete production chain from sheet metal processing to final testing. Our facility spans over 20000 square meters in Jiangxi. We serve as a qualified supplier for State Grid and China Southern Power Grid. This experience taught us the importance of reliable voltage measurement. Every unit we produce supports accurate energy accounting and system protection.

Our Oil Immersed Voltage Transformer goes through careful manufacturing processes. Our technicians follow standardized procedures for winding, drying, and vacuum oil filling. These steps ensure consistent quality across all units. We understand that overseas projects need proper documentation. We provide complete factory test reports and certificates with every shipment. Our after-sales team responds to technical questions within 24 hours. We offer a 12-month warranty from the delivery date. The product series includes JDJ, JDXF, JDJJ2, and JDCF models. Primary phase voltage is Un/√3. Secondary voltage is 0.1/√3 kV. Residual winding voltage is 0.1/3 kV. Installation is outdoor rated. When you choose our Oil Immersed Voltage Transformer, you select a partner with solid technical capabilities. We deliver equipment that performs reliably in demanding grid applications.
