3.Key Features & Advantages
1. Unmatched Durability
The product uses hot-dip galvanized steel and silicone rubber insulation to resist corrosion, UV exposure, and temperature fluctuations (-40°C to +55°C). Its sealed bearings and self-lubricating joints ensure smooth operation even after 10,000 mechanical cycles.
2. Enhanced Safety
- Dual-Break Insulation: Creates two visible isolation gaps for maintenance safety.
- Interlock System: Prevents accidental closure of the earthing switch under load.
- Low Leakage Current: <1μA at rated voltage minimizes arc risks.
3. Smart Grid Readiness
Optional IoT sensors enable real-time monitoring of contact temperature, blade position, and environmental conditions—ideal for integration with SCADA systems.
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 horizontal pantograph design uses a rotating insulator column to lift the conductive blade, creating a clear isolation gap. The earthing switch provides a safe discharge path for residual currents. All operations are manual or motorized (optional), with mechanical indicators for blade status.
