Comewill factory’s quality LJWD-10.12 Oil immersed Current Transformer is suitable for indoor and outdoor scenarios in 50Hz power grids, and can complete current measurement, energy metering, and relay protection work; It can operate continuously at 120% rated current, and can work stably in the face of grid load fluctuations.
At the same time, it can adapt to high-altitude environments within 4000m and temperature ranges from -25 ℃ to+40 ℃. It can operate reliably in diverse and harsh environments, making it a high reliability procurement choice for power engineering companies and grid operation and maintenance units.
Whether it is the construction of power grids in high-altitude areas, the implementation of distribution projects in different climate zones, or the supporting of heavy-duty distribution systems in industrial plants, choosing Welcome (Wenzhou) Electric Co., Ltd.'s LJWD-10.12 Oil immersed Current Transformer can provide stable operating performance and full cycle technical support. For scenarios such as bulk procurement of complete equipment for product adaptation and centralized procurement of power grid renovation projects, if you want to learn about procurement details or customize supporting plans, feel free to consult at any time!
L: It means "current transformer", which directly specifies the product category and belongs to the key components responsible for measurement and protection in the distribution system;
J: Representing the "oil immersed steel fuel tank" structure, this design can make the equipment more durable, with better insulation effect, suitable for long-term stable operation, and is a reliable choice in engineering procurement;
W: It can be used both indoors and outdoors, without worrying about the installation environment, making the selection process more worry free;
D: Related to protection and control functions - those with D are dual secondary windings, while those without D are single secondary windings, which can be selected according to different measurement and protection needs to meet different procurement requirements;
10.12: Refers to the rated voltage, suitable for 10kV or 12kV power systems, just covering the mainstream voltage level of medium voltage distribution, which can be used for power grid renovation and complete equipment procurement.
From the model, the product structure, applicable scenarios, and voltage levels can be clearly understood. Welcome (Wenzhou) Electric Co., Ltd's LJWD-10.12 current transformer makes procurement selection more direct. Whether it's bulk procurement or on-demand selection, it can accurately meet project requirements. If you want to know which specific scenarios are suitable for different winding types, just ask for purchasing details at any time!
TheLJWD-10.12 Oil immersed Current Transformer produced by Comewill fully considers the requirements of different distribution scenarios in terms of environmental adaptability and can operate stably under various working conditions
Installation site: It can be deployed both indoors and outdoors without being limited by the installation environment. The location of the power distribution project is more flexible, making it a highly adaptable choice in engineering procurement;
Environmental temperature: able to withstand temperature changes from -25 ℃ to+40 ℃, whether in low-temperature areas in the north or high-temperature environments in the south, it can work normally;
Air humidity: It can withstand up to 95% relative humidity and can be used with confidence in humid climate areas, reducing the risk of malfunctions caused by humidity;
Installation altitude: The altitude should not exceed 2000 meters, which can be met by most urban and mountainous power distribution projects without additional altitude adaptation treatment;
Pollution level: Meet the Level II standard, and the insulation performance will not be affected in industrial environments or outdoor scenes with slight pollution.
The environmental adaptability of this transformer covers the actual needs of most power distribution projects. Welcome (Wenzhou) Electric Co., Ltd ensures the reliable operation of the equipment in diverse environments from a design perspective. Whether it is bulk procurement for new construction projects or component replacement for renovation projects, it is a worry free procurement choice. If you want to learn more about environmental adaptation details, feel free to consult procurement related matters at any time!
