What are the essential hand tools every lineman or electrical technician needs for overhead transmission line (OHTL) work?
2025-07-20For efficient and safe OHTL work, a lineman or electrical technician relies on a comprehensive set of specialized hand tools:
-
Conductor Grips / Come-Alongs: For securely holding, pulling, and tensioning conductors during splicing, sagging, and maintenance. These vary by conductor type and size.
-
Hydraulic Cutters and Crimpers: Essential for precise cutting and strong, reliable compression splices and connections on various conductor types and sizes.
-
Insulated Hand Tools (Pliers, Wrenches, Screwdrivers): Designed with dielectric properties to protect against electrical shock when working near energized components. Certified to standards like IEC 60900.
-
Hot Sticks / Live-Line Tools: Fiberglass-reinforced insulating sticks with interchangeable heads for performing tasks on energized lines from a safe distance.
-
Grounding Sets: Temporary grounding clamps and cables for safely de-energizing lines and creating equipotential zones.
-
Voltage Detectors & Phasing Tools: Crucial for verifying the presence or absence of voltage and ensuring correct phase rotation before and during work.
-
Cable Strippers & Preparation Tools: For cleanly removing insulation and semi-conducting layers from conductors to prepare for splicing or termination.
-
Torque Wrenches: To ensure fasteners and connections are tightened to precise specifications, preventing loose connections or over-stressing components.
-
Climbing Gear (for pole/tower work): Lineman's belts, body belts, fall arrest systems, and climbing spurs, all subject to rigorous safety standards.
-
Specialized Measuring Tapes & Sagging Devices: For accurate measurement of spans, clearances, and conductor sag.
