When Lightning Strikes Twice: How a Relay Saved a Wind Farm
Last spring, technicians at a coastal wind farm in Guangdong faced recurring voltage spikes during storm seasons. Their existing relays couldn’t handle the 690V system’s irregular fluctuations – until they deployed CHORDN AS10-2A. This unassuming 45mm-wide device reduced downtime by 37% in the first quarter, according to their maintenance logs.
Engineering Behind the Beast
The AS10-2A isn’t your grandpa’s relay. With arc-quenching technology that achieves 0.8ms breaking speed (30% faster than industry average), it’s become the go-to solution for:
- Motor control centers in cement plants
- Shipboard power distribution systems
- Mining equipment protection circuits
‘We’ve pushed 2,500A through it during stress tests – the contacts didn’t even flinch,’ reveals Chen Wei, R&D head at CHORDN.
Smart Grid’s New Best Friend
Shanghai’s Yangshan Port automated cranes now feature AS10-2A clusters handling 690V/50Hz power. The result? 18% energy savings through precise load management. ‘Its 500,000 mechanical operations rating means we inspect annually instead of quarterly,’ says port electrical engineer Zhang Li.
