What are the essential hand tools and accessories required for efficient OHTL stringing?
2025-07-20Beyond the major stringing equipment, a range of specialized hand tools and accessories are critical for efficient, safe, and precise OHTL stringing. These include:
-
Conductor Grips / Come-Alongs: Used for securely holding and tensioning conductors during splicing, sagging, and other operations.
-
Stringing Blocks / Conductor Sheaves: Installed on towers to support and guide conductors, reducing friction during stringing. These come in various sizes and configurations (single, bundle) and are often lined with materials like nylon or polyurethane to protect the conductor.
-
Anti-Twist Swivels: Placed between the pulling rope and conductor to prevent twisting and torque buildup, especially important for bundled conductors or OPGW.
-
Running Boards / Pulling Socks: Connect multiple conductors for simultaneous stringing, ensuring even tension and preventing individual conductor damage.
-
Pilot Wire / Anti-Twisting Steel Ropes: Used for initial pulling, designed with specific constructions (e.g., hexagonal, braided) to resist rotation.
-
Dynamometers / Tension Meters: Essential for accurately measuring the tension applied to conductors, critical for achieving target sag and ensuring safety.
-
Hydraulic Cutters and Crimpers: For precise cutting and splicing of conductors, ensuring strong and reliable connections.
-
Grounding Equipment: Temporary grounding clamps and cables are vital for safety, de-energizing lines before work.
-
Personal Protective Equipment (PPE): Insulated gloves, hard hats, safety glasses, harnesses, and fall arrest systems are non-negotiable for worker safety.
