Product Details

Wind protection devices are mainly used to protect wind power system equipment, sensitive electric and electronic parts in turbine system from lightning strikes, widely applied in power line protection in wind power system's distribution box, and other AC distribution box.

Feature of Wind Protection Devices

1. Own designed temperature control circuit-breaking technology and built-in overcurrent protection circuit to completely avoid fire danger.

2. Working state and failure state are clear and intuitive.

3. Kevin wiring is workable.

4. Convenient installation and simple maintenance.

5. Remote alarm Status indicator

6. Exquisite workmanship, can work in hostile environments such as acid, alkali, dust, salt spray, and humidity for a long time.

Application of Wind Protection Devices

Applied to wind power protection system, Wind power generator.

Low voltage transformer box, Output of second power equipment, US and European box are applicable.
