LJWD-10.12 Oil-Immersed High Voltage Current Transformer High Sensitivity Current Transformer
Product descriptions
The LJWD-10.12 Oil-Immersed High Voltage Current Transformer is a steel-tank, oil-immersed device designed for 10kV and 12kV AC power systems (50Hz/60Hz). It is widely used for current measurement, energy metering, and relay protection in urban and rural power grids, substations, and industrial transformer stations. Built for reliability, it can operate continuously at 120% of rated current, withstand harsh outdoor conditions, and deliver long-term stable performance at altitudes up to 4000m and ambient temperatures from -25°C to +40°C.
Service conditon ·Installation: Indoor & outdoor ·Temperature: -25°C to +40°C ·Humidity: ≤95% relative humidity ·Altitude: ≤2000m (customizable up to 4000m) ·Pollution Class: Class II Construction & Features ·Oil Tank Design: Waterproof & snowproof cover, oiling valve, and diaphragm to reduce oxidation and extend service life. ·Vacuum Oil Treatment: Vacuum oil-filtering and oil-injection improve insulation and cooling efficiency. ·Thermal Stability: 187.5 times enhanced thermal stability for demanding power systems. ·Flexible Configurations: ·Single/Double secondary winding ·Single/Double ratio options ·Accuracy Classes: 0.2, 0.5, 1.3 (D) for both measurement and protection.
Technical Parameters ·Rated Primary Current: 5A – 1500A ·Rated Secondary Current: 5A ·Accuracy Class: 0.2, 0.5, 3 (customizable combinations) ·Rated Short-Time Thermal Current: Up to 30kA ·Rated Dynamic Current: Up to 50kA ·Rated Insulation Level: 12/42/75kV ·Standards: GB1208-1997, IEC standards
