PIAB Dynamometer for Wire Tension Control Case Study
Dynamometer provides force measurement for tension control in lightning protection wire
In Jackson, Michigan, US, Consumers Energy have had problems controlling the tension forces in the messenger wire which serves as protection from lightning to the entire aerial spacer cable system. The system allows for reductions in requirements for tree trimming and major pruning, as it allows trees to grow closer than a bare wire system. The importance of being able to accurately measure tension in the messenger wire is vital, especially in regards to climatic changes that cause traction and contraction in the wire. A wire that is not tensioned correctly could fatigue and damage the spacer cable system.
Product: PIAB Dynamometer for force measurement to control tension and weights
The PIAB Dynamometer, Type Dx1,5 Capacity 3300 lb. (1500 kg) is a force measurement instrument that is ideal for measuring tension in the HENDRIX Aerial Spacer Cable System (Overhead Power Distribution System). It is used in situations where accuracy, reliability, and safety are critical in the measurement and control of tension forces and weights. The PIAB Dynamometer is integral in lifting devices and in weighing test-loads for hoist and crane inspections.
Solution:
Based on practical application testing, Consumers Energy’s standardization engineer, Terry J. Orban, noted that the PIAB Dynamometer is "Very light, durable, handy and easy to use. It does not to be re-calibrated as other types of instruments do."
