Description
Product Overview
The 35kV Outdoor High-Voltage Vacuum Load Break Switch is a core power distribution device engineered for 3-phase AC 50/60Hz power grids. Specialized in making, carrying and breaking normal load currents, as well as withstanding short-circuit currents for specified durations, it is the ideal switching solution for outdoor 35kV medium and high-voltage distribution networks.
Designed with a weatherproof enclosure and vacuum interruption technology, it delivers unmatched reliability in harsh outdoor environments, widely used in overhead lines, pole-mounted substations, and rural power grid upgrading projects.
Core Features
- Vacuum Interruption Technology: Arc extinction in a vacuum chamber ensures zero gas leakage, maintenance-free operation and a long electrical service life.
- Rugged Outdoor Enclosure: IP65-rated protection against rain, dust, corrosion and extreme temperatures (-40°C to +60°C).
- High Mechanical Strength: Reinforced insulation structure adapts to strong winds, earthquakes and other outdoor harsh conditions.
- Dual Operation Modes: Optional manual or electric spring mechanism supports on-site and remote control.
- Clear Isolation Break: Visible disconnect point meets safety requirements for maintenance and troubleshooting.
