Lightning countermeasures Lightning transformer for power supply Single type ST type
Sankosha Co., Ltd.
About This Product
High-performance lightning-resistant transformer with a surge transfer rate of 1/1,000 or less. 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 shielding (protects between the lines) and a power supply SPD (protects between the lines), shutting out abnormal voltages caused by induced lightning surges and ground potential rises.
