Q:
Are your power line tools suitable for live-line work? What safety certifications are required?
A
Yes. Our live-line tools (e.g., insulated crimpers, hot sticks) are certified to IEC 60855 and ANSI/ASTM F711. Key requirements: ① Dielectric strength ≥100kV/ft for hot sticks; ② Non-conductive FRP material with zero surface defects; ③ Regular dielectric testing (annually recommended). All tools come with test reports and certification labels for on-site compliance checks.
Q:
How to select the correct tension tool for insulator string replacement?
A
① Match the tool load capacity to the insulator's rated mechanical load (e.g., 220kV insulators use 120kN-grade lead screw tools); ② For "V" type insulator strings, choose adjustable angle load-bearing tools (e.g., aluminum alloy ladder-type bearing rods) to avoid bowing; ③ Ensure compatibility with conductor size (120-400mm²) and tower hardware. Our technical team provides customized tool selection based on project drawings.
Q:
What are the maintenance requirements for power line tools to ensure safety?
A
① Pre-use inspection: Check for cracks, corrosion, or loose bolts (replace immediately if damaged); ② Post-use care: Clean with non-conductive detergent and store in dry, dust-free cases; ③ Periodic testing: Load-bearing tools (e.g., pulling grips) require annual load testing; insulated tools need dielectric testing every 6-12 months; ④ Lubricate moving parts (e.g., crimper jaws) with non-conductive grease quarterly.
Q:
Can your tools be used for both AC and DC transmission lines?
A
Yes. Our universal tools (e.g., insulated cutters, conductor grips) are designed for 10kV-500kV AC/DC lines. Key adaptations: ① DC-compatible insulated tools have enhanced surface leakage resistance (≥10¹¹Ω); ② Tension tools use corrosion-resistant materials (316L stainless steel) to withstand DC electrolysis. Please specify the line type when placing orders for precise configuration.
