3.Key Features & Benefits
1. Enhanced Durability & Performance
- Lightweight & Strong: Aluminum alloy conductors reduce weight by 40% compared to traditional materials while resisting corrosion.
- Low-Maintenance Operation: Sealed motion mechanisms and self-lubricating bushings cut servicing needs by 60%.
- Space-Saving Design: Modular shared-contact layouts save 30% space in 252–420 kV installations.
2. Smart Grid Compatibility
- Hot-dip galvanized bases withstand extreme temperatures (-40°C to +85°C) and humidity.
- Optional IoT sensors enable real-time monitoring for predictive maintenance.
3. Safety First
- Mechanical/electrical interlocks prevent unsafe operations between main and earthing blades.
- Horizontal insulation breaks ensure safe live-line maintenance.
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?
This outdoor disconnector uses a pantograph mechanism to physically separate circuits. When activated, its dual blades create a visible air gap, ensuring electrical isolation. The enclosed transmission system prevents dust/sand ingress, while flexible joints allow easy installation on uneven terrain.
