Product Details
Vacuum Permanent-Magnet Horizontal On-Load Tap Changer
Vacuum Permanent-Magnet (horizontal) OLTC
This switch is suitable for three-phase oil-immersed transformers with a frequency of 50 or 60 Hz, a maximum operating voltage of 12 kV or less, and a rated current of 63 A or less.
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 switch employs vacuum arc extinction, does not contaminate transformer oil, and achieves true maintenance‑free operation. It features a dual‑stable permanent‑magnet mechanism that ensures high reliability and long mechanical life. Its compact design and horizontal mounting configuration help conserve internal space within the transformer tank. The controller includes a built-in Wi‑Fi wireless communication module, enabling wireless control via a dedicated mobile app. An optional GPRS remote‑communication module is available for long‑distance data retrieval, parameter configuration, and status monitoring. The device meets all performance requirements of State Grid for smart distribution transformers.
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.
