Lightning countermeasures Lightning transformer for power supply Cabinet type STC type
Sankosha Co., Ltd.
About This Product
High-performance lightning-resistant transformer with a surge transfer rate of 1/1,000 or less. A product that houses a lightning-resistant transformer (single type) in a cabinet. We can customize wiring types, voltage, capacity, coating, etc. to meet customer requests.
Lightning transformers used for surge protection in equipment rooms, wireless relay stations, mobile phone base stations, and other low-voltage distribution line equipment power supplies. Consists of a high-voltage insulation transformer with electrostatic shield (protects between the ground and the ground) and a power supply SPD (protects between the lines), shutting out abnormal voltages caused by induced lightning surges and ground potential rises.
