Design and Construction of a Cable Stripping Tool for 50 sq.mm. Size

Abstract

The objectives of this research were to: 1) design and create the cable stripping tool for 50 sq.mm. size, 2) compare the time for stripping compression type cables with the cable stripping tool for 50 sq.mm. size and a cutter and a cutter for PVC pipe, 3) compare the time for stripping 2-bolt cable, 5.5 cm long using the cable stripping tool for 50 sq.mm. size and a cutter, and a cutter for PVC pipe, 4) compare the time for stripping 3-bolt cable 9 cm.long using the cable stripping tool for 50 sq. mm. size and a cutter, and a cutter for PVC pipe, and 5) assess users’ satisfaction towards the use of the cable stripping tool for 50 sq. mm. size. The population and sample were external network operation staffs of Songkhla Province derived by purposive sampling technique. The research instrument included operation time recording forms and satisfaction questionnaires. The statistics used in the research include the average, standard deviation, and percentage.

The research results showed that: 1) the developed cable stripping tool for 50 sq. mm. size was validated and inspected by the experts. 2) The operation time comparison showed that when stripping squeeze type cables 5 cm. Long with the cable stripping tool for 50 sq. mm size,  an average time decreased of 94 seconds accounting for 65.73 percent compared to a cutter and 57 seconds accounting for 53.77 percent compared to a cutter for PVC pipe. 3) When stripping 2-bolt cable, 5.5 cm long, the operation time decreased by 103 seconds accounting for 65.60 percent compared to the cutter, and 79 seconds accounting for 59.39 percent compared to the cutter for PVC pipe. 4) When stripping a 3-bolt cable 9 cm long, the operation time decreased by 203 seconds accounting for 70.73 percent compared to the cutter, and 134 seconds accounting for 61.46 percent compared to the cutter for PVC pipe. 5) Finally, it was found that the users’ satisfaction towards the cable stripping tool for 50 sq. mm. size was the highest.
