Link stick 8 meters

A link stick

generally refers to an insulated tool used by electrical utility workers (linemen) to safely manipulate energized electrical lines and equipment from a distance. More:

Here’s a breakdown of what they are and their key characteristics:

• Purpose: They are designed to provide electrical insulation between the worker and live electrical components. This allows linemen to perform tasks like:
  • Opening and closing solid links (switches) to control circuits.
  • Carrying out maintenance on live line surge arrestors.
  • Providing restoration to overhead networks without de-energizing the lines.
  • Supporting conductors and isolating rope blocks or hoists from energized conductors during maintenance.
  • Spreading and holding conductors apart for mid-span clearances.
• Material: Link stick is primarily made from high-grade fiberglass (Fiberglass Reinforced Polymer or FRP) due to its excellent insulating properties, light weight, and mechanical strength. Some components might be made from aluminum alloy, bronze alloy, or high-strength steel.
• Types: There are various types designed for specific tasks, including:
  • Telescopic : These are extendable, allowing workers to reach different lengths as needed. They can range from a few feet to over 50 feet.
  • Strain Used to support conductors and provide insulation for rope blocks and hoists.
  • Roller: Designed to spread and hold conductors apart.
  • Spiral : Used to isolate rope lines, hoists, and rope blocks.
• Voltage Rating: Link sticks are rated for specific voltage levels, often ranging from low kilovolts (kV) up to several hundred kV, and some specialized ones can handle over a million volts. It’s crucial to use a link stick with the appropriate insulation rating for the voltage being worked on.
• Safety Features:
  • Insulation: The primary safety feature, preventing electrical shock.
  • Telescopic design with locking mechanisms: Ensures stability when extended.
  • Ergonomic grips: For secure handling, even in wet conditions.
  • Universal end fittings: To attach various tools and accessories.
  • Compliance with standards: Manufactured to meet or exceed industry safety standards like ASTM F711, ASTM F1826, and OSHA 1926.951(d).

In essence, a link stick is a critical safety tool for anyone working on or near live electrical power lines.
