This type of OLTC is applicable for the oil-immersed three- phase transformer that its frequency with 50、60Hz,the equipment below 12kV voltage and rated current below 63A.
This type of OLTC adopts vacuum arc extinguishing, no pollution transformer oil to achieve maintenance free. This OLTC adopts the bistable permanent magnet mechanism with high reliability and long mechanical life; It is designed in miniaturization and horizontal installation to save the internal space of the transformer oil tank. The controller has built-in WiFi wireless communication module and can be wireless controlled through special mobile app. GPRS remote communication module is optional to fit to remote data query, parameter setting and state controlled. It is satisfied to the requirements of State Grid for the performance of intelligent distribution transformer.
