Development of a Guy Wire Wrapping Tool for Electrical Utility Poles: A Case Study of the Provincial Electricity Authority (PEA)

Abstract

This experimental research aimed to: 1) design and develop a steel guy-wire wrapping tool for utility poles. 2) evaluate the quality of the developed tool. 3) assess its operational efficiency. and 4) investigate user satisfaction with the tool. The sample group consisted of 20 participants, including electrical operation technicians from the Khlong Lan Branch of the Provincial Electricity Authority (PEA) and undergraduate students in the Electrical Technology program. The research instruments included: 1) a performance test record form, 2) a quality assessment form, and 3) a satisfaction questionnaire regarding the steel guy-wire wrapping tool. The data were analyzed using mean, standard deviation, and independent t-test. The research findings revealed that: 1) the developed steel guy-wire wrapping tool was capable of effectively wrapping both low-voltage and high-voltage guy wires. The wrapped wires remained secure during operation without loosening, exhibited consistent tightness, and complied closely with the Provincial Electricity Authority standards for guy-wire installation.   2) the overall quality of the tool was rated at the highest level. (  = 4.61, S.D. = 0.47) 3) the tool demonstrated high operational efficiency. The average time required for wrapping low-voltage guy wires was reduced by 48.60 minutes (53.64%), while the average time required for wrapping high-voltage guy wires was reduced by 87.00 minutes (50.87%). The results of the independent t-test indicated that the operating times before and after using the developed tool for both low-voltage and high-voltage applications were significantly different at the .05 level, confirming the effectiveness of the developed tool. and 4) overall user satisfaction with the steel guy-wire wrapping tool was rated at the highest level.
