What types of transformers does China Electrical supply for power systems?

China Electrical offers a comprehensive range of transformers, including outdoor/indoor casting resin voltage/current transformers, oil-immersed (L(A)B, LVB(T), JDCF series) and SF6 gas-insulated (LVQB, JDQXF series) models. These cover 10kV indoor voltage transformers, high-precision current transformers for laboratories/industries, and units for outdoor power transmission/distribution. Each type is engineered for specific scenarios—with casting resin transformers resisting harsh outdoor conditions, oil-immersed models ensuring accurate measurement, and SF6-insulated units delivering superior insulation for high-voltage applications, fully meeting diverse power system needs.
Our transformers serve diverse scenarios, including traditional power transmission/distribution, laboratory testing, industrial production, and new energy projects. Specific applications include outdoor power grids (with weather-resistant casting resin transformers), indoor power systems (10kV indoor models), laboratory current/voltage measurement (high-precision oil-immersed transformers), and new energy integration (PV, wind power, energy storage). They are also used in agricultural irrigation (solar pumps), urban infrastructure (solar street lights), commercial/industrial storage & charging, and sewage treatment projects. Each transformer is engineered to excel in its target scenario, ensuring optimal performance and reliability.
Overseas customers can order transformers by contacting our team via email ([email protected]) or phone (+86-15998272128). The process starts with providing project details: application field, technical specifications (voltage, capacity, dimensions), drawings, and order quantity. Our experts then recommend suitable models, provide quotes, and confirm customization requirements if needed. After order confirmation, we handle production, quality inspection, and logistics—including optimal transportation routes and customs clearance services. Throughout the process, we maintain transparent communication, updating customers on production progress and delivery status, ensuring a seamless purchasing experience.
