Pole-Mounted Isolating Switch
High-voltage distribution switch designed for 10kV and 35kV overhead power lines. This essential utility device provides secure circuit isolation for maintenance and equipment safety.
Clear Isolation: Creates a visible insulation gap for safe line and transformer maintenance.
Risk Prevention: Effectively prevents hazards caused by accidental energization or induced voltage.
Reliable Performance: Engineered for outdoor utility poles and towers in demanding electrical environments.
Overview
The Pole-Mounted Isolating Switch is a high-voltage distribution switch installed on outdoor utility poles or towers, mainly used for 10kV and 35kV overhead power lines. It is a fundamental device in distribution networks, providing circuit isolation and ensuring maintenance safety.
As the switch has no arc-extinguishing capability, it cannot interrupt load current or short-circuit current. It should only be operated when the line is unloaded and de-energized.
After disconnection, the switch forms a clear and visible insulation gap, providing reliable electrical isolation for line maintenance, transformer maintenance and equipment replacement, while helping prevent risks caused by accidental energization or induced voltage.
Applications
- Distribution network line sectioning and interconnection
- Substation supporting facilities
- Safe isolation for maintenance
- Rural and urban power grid renovation
- Special applications: wind farm and PV power station collector lines, railway traction power supply systems, and outdoor power supply lines for industrial and mining enterprises
