In extreme weather conditions where the wind speed reaches 30 meters per second, the utility poles need to withstand a lateral tensile force of more than 500 kilograms. However, a set of high-quality guy grip that complies with the IEEE 887 standard can increase the tensile strength of the guy wire to more than 120 kilonewtons and ensure that the deviation of the inclination Angle of the pole circuit is less than 1 degree. According to the statistics of the National Electrical Safety Code (NESC) of the United States, the pole roads correctly using guy grip can have a collapse probability that drops sharply from 15% to less than 0.5% when encountering a Category 4 hurricane. For example, during the period when Typhoon Lekima hit the southeast coast of China in 2020, The failure rate of the lines reinforced with high-standard guy grip is 90% lower than that of ordinary lines.
From the perspective of the total life cycle cost analysis, the initial investment for installing a set of guy grip is approximately $200 to $500, but it can extend the maintenance cycle of the poles and lines from 5 years to over 25 years, with a return on investment of more than 300%. Industry research shows that the average repair cost for pole road collapse accidents caused by ignoring the guy wire anchoring system is as high as 20,000 US dollars per incident, which is 40 times that of preventive investment. Taking the case of Pacific Gas & Electric Company (PG&E) in the United States as a reference, it was held responsible for over 13.5 billion US dollars in a wildfire lawsuit caused by line stability issues in 2019, highlighting the strategic value of foundation anchoring equipment in risk management.
At the level of materials science, modern guy grip is typically made of hot-dip galvanized steel or aluminum alloy, with a weight controlled between 5 and 15 kilograms. However, it can fixedly withstand more than 10,000 fatigue stress cycles, and its corrosion resistance ensures a service life of over 30 years in a salt spray environment with a humidity of 95%. In the technological upgrade of Australia’s energy network in 2022, by replacing traditional fixtures with the new guy grip, the rate of pole and line breakage accidents in the entire transmission network decreased by 70%, and the inspection efficiency was increased by 50%.
Field application data show that in the complex environment of mountainous terrain with a drop of more than 500 meters, guy grip can extend the rod distance to 80 meters through distributed tension adjustment, increasing the coverage by 20% compared with the standard design. In the rural broadband deployment project of the Indian telecommunications department in 2021, by systematically configuring the guy grip device, the installation speed of optical fiber overhead lines was increased by 35%, the total project budget was saved by 15%, and at the same time, the fluctuation of optical signal attenuation caused by pole shaking was controlled within 0.2dB. When we turn our attention to the construction of the future smart grid, guy grip, as a key anchor point of the physical infrastructure, its accuracy and reliability are directly related to whether the positioning error of 5G micro base station deployment can be controlled within the millimeter range.
