3.Key Features & Advantages
1. Built to Withstand Extreme Conditions
The product uses hot-dip galvanized components and sealed transmission mechanisms to resist corrosion in coastal or high-humidity areas. Its aluminum alloy profile enhances heat dissipation, while stainless steel contact springs maintain stable conductivity during frequent operations.
2. Maintenance-Free Operation
With a stainless steel pin/bushing system and externally compressed contact springs, the GW5 requires minimal upkeep. The horizontal pantograph design reduces friction during switching, extending service intervals by 40% compared to traditional models.
3. Customizable for Your Grid Needs
Choose from Arctic variants (-60°C operation), compact models for urban substations, or IoT-enabled versions with predictive maintenance sensors. All GW5 switches support modular retrofitting into existing infrastructure.
4.Where It's Used?
Be used in a wide range of industries.
Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.
Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.
Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works?
The GW5’s dual-break isolation system creates two visible gaps when open, providing clear safety confirmation. Its pantograph mechanism moves horizontally to minimize arcing, while optional grounding switches interlock with main blades to prevent accidental activation during maintenance.
