Home/Outdoor High-Voltage Switchgear/Outdoor Load Break Switch/BPS-12kV Portable By-pass Load Break Switch (Quick-Connect Type for Live-line Work) BPS-12kV Portable By-pass Load Break Switch (Quick-Connect Type for Live-line Work)
The BPS series is a specialized component for uninterrupted power maintenance (Live-line work). It features a lightweight stainless steel tank and high-voltage quick-plug connectors, allowing operators to rapidly deploy temporary bypass channels to maintain power during circuit repairs.
Electrical ProductsProduct Features of By-pass Load Break Switch
Quick-Connect Interface: Equipped with six 400A heavy-duty sockets for “second-level” cable attachment without the need for bolting or specialized tools.
Portability & Protection: Reinforced lifting lugs and non-slip support feet make the unit ideal for utility truck transport and rapid on-site deployment.
Integrated Parameter Monitoring: The control panel provides real-time readings of phase current, gas pressure, and operation counts to ensure safety during live-line procedures.
Dual Operation Modes: Supports manual hook-stick operation from the ground and remote electrical operation via a smart terminal.
