LJW1-10、LJWD-10 Outdorr Oil-immersed type current transformer
The UW1-10 and LJWD-10 series Current Transformers feature oil-immersed insulation and are designed for outdoor installation. They are intended for use in 50 Hz power systems for the purposes of current measurement, energy metering, and relay protection, making them particularly suitable for outdoor substations in rural areas. These transformers are single-phase, oil-immersed, and self-cooling units designed for outdoor operation. They are filled with No. 25 transformer oil, with the oil level positioned approximately 15 mm below the tank cover. The tank cover is fitted with an oil-filling plug (which includes a vent hole) and is protected by a rain- and snow-proof hood. The iron core of this transformer series features an external-iron configuration, constructed by stacking 0.35 mm thick silicon steel laminations. Both the primary and secondary coils are mounted directly onto this iron core.
Description LJW1-10 / LJWD-10 Outdoor Oil-immersed Current Transformer is designed for 10kV power distribution systems. It is used to accurately convert primary current into standardized secondary current for metering, protection, and control applications. With its oil-immersed insulation system and outdoor design, the transformer ensures reliable performance, high accuracy, and long service life under various environmental conditions.
Structural Features The transformer adopts an oil-immersed insulation structure with a fully sealed design, providing excellent dielectric performance and efficient heat dissipation. Its compact and robust construction ensures stable measurement accuracy, while strong resistance to environmental factors such as moisture, pollution, and temperature variations guarantees reliable long-term outdoor operation.
Applications 1.10kV distribution networks 2.Pole-mounted substations 3.Power distribution and control systems 4.Energy metering systems
