Pole fuse switch disconnector for protecting underground cables

Product Introduction

The Pole Fuse Switch Disconnector for Protecting Underground Cables is a specialized electrical device designed to safeguard underground low-voltage (LV) cable networks. Mounted on poles at junction points between overhead lines and underground cables, it acts as a critical protective barrier—preventing damage to buried cables from overloads, short circuits, or voltage surges. It integrates switching, isolation, and fuse-based protection to manage power flow between overhead grids and underground systems, ensuring reliable operation in residential, commercial, and industrial areas where underground cabling is prevalent.

Core Features

• Underground Cable-Specific Protection：Tailored to address the unique risks of underground cables (e.g., moisture-induced faults, insulation degradation), it provides targeted protection against overloads and short circuits that could damage buried conductors. Prevents costly cable replacements and network outages.

• Seamless Overhead-to-Underground Integration：Designed to connect overhead lines with underground cables, creating a secure transition point. The pole-mounted structure simplifies installation at cable entry/exit points (e.g., near transformers or distribution cabinets), ensuring efficient power transfer between systems.

• Enhanced Isolation for Cable Maintenance：Enables safe isolation of underground cable sections during repairs or inspections. Clear position indicators and lockable open positions prevent accidental re-energization, allowing technicians to work on buried cables without risk of electric shock.

• Weather-Resistant Construction：Built with durable, corrosion-resistant materials (e.g., coated metals, UV-stable plastics) to withstand outdoor elements at pole-mounted locations. Sealed fuse compartments protect internal components from moisture, dust, and debris—critical for reliable operation near underground cable entry points.

• Easy Fault Identification：Many models feature visual fuse failure indicators, allowing quick identification of tripped fuses. This speeds up troubleshooting, reducing downtime for underground cable networks and ensuring faster restoration of power.
