When Machines Demand Uncompromising Reliability
In a manufacturing plant in Guangdong, a production line suddenly halted due to a relay failure, causing $18,000 in hourly losses. This incident sparked engineers’ search for robust solutions – leading them to Holly’s HC10GG series. With 98.7% operational stability in third-party tests, this 690V/10A relay now protects critical paths in over 200 Chinese factories.
Precision Engineering for Extreme Environments
The HC10GG’s secret lies in its military-grade contacts using AgSnO₂ material, reducing contact resistance to <2mΩ even after 100,000 operations. A Shanghai metro project reported zero failures across 15,000 installed units despite -25℃ winters and 45℃ summer tunnel temperatures.
Smart Grids Get Smarter Protection
During Zhejiang province’s 2023 grid upgrade, HC10GGs enabled 0.3ms cutoff speeds in smart switches – 40% faster than previous models. Grid operators measured a 62% reduction in transient voltage incidents after deployment.
- Withstands 6kV lightning surges (IEC 61000-4-5 certified)
- 72% smaller footprint vs traditional industrial relays
- IP67 protection against factory dust/oil mist
New Energy Applications Emerge
A leading EV charger manufacturer replaced European relays with HC10GGs, achieving 99.1% efficiency while cutting costs by 35%. Their 480kW supercharger stations now complete 150+ daily charge cycles without thermal derating.
