Manual Bypass Switch
The 12kV/24kV engineering-type bypass load switch is the
core device for bypass integrated operation technology. This
switch utilizes flexible power cables, self-locking quick plug-in
cable connectors, bypass switches, and mobile transformer
substations to build various power distribution units in a
modular manner, providing bypass power supply to users
It allows maintenance personnel to perform line maintenance
under uninterrupted power supply conditions and provides
temporary power supply for emergency repairs of challenging
cable faults. This reduces the scope of power outages,
minimizes the impact on users, and enhances power supply
reliability.
The bypass load switch utilizes SF6 gas, known for its
outstanding insulation and arc-extinguishing properties,
combined with an advanced main circuit structure.
