Insulated operating rod assembly of high-voltage grounding wires — a core component of high-voltage grounding wire sets, used for grounding safety protection during power outage operations in electrical systems. Here’s a detailed introduction:
Core Function
It serves as the "operation & connection end" of high-voltage grounding wires:
The top metal clamp clamps onto live conductors (e.g., overhead lines, busbars) to connect equipment/lines to the grounding system.
The green insulated rod ensures electrical isolation between operators and high-voltage live parts, preventing electric shock risks.
Structure & Materials
1. Top Metal Clamp:
Made of stainless steel or copper-plated material, equipped with a spiral fastening structure (the knob allows clamping conductors of different specifications). It has low contact resistance and good conductivity, enabling stable connection to wires.
2. Insulated Rod Body:
The main body is made of epoxy resin fiberglass (green tube), which has strong insulation performance and high mechanical strength. It can withstand high-voltage electric fields (compatible with voltage levels like 10kV, 35kV) while being lightweight and easy to carry and operate.
3. Handle Section:
The black rubber/plastic handle at the bottom increases grip friction for safer operation.
Application Scenarios
As a component of high-voltage grounding wires, it is mainly used for:
Maintenance of de-energized overhead transmission lines;
Grounding operations for busbars, switchgear, etc., in substations and distribution rooms;
Grounding protection for other high-voltage electrical equipment during outages.
Usage Precautions
1. Before use, check if the insulated rod has cracks or damage, and if the metal clamp is rusted or loose;
2. Ensure it matches the corresponding voltage level (the applicable voltage is usually marked on the rod);
3. During operation, keep the effective insulation length of the rod (avoid touching the metal part with hands).
It is a key protective component for "electric shock prevention" in electrical operations and must be used strictly in accordance with regulations.
