Stub Setting Fixture Prototype on High Voltage Overhead Transmission Line Tower Installation

High voltage overhead transmission line is a transmission tower used to conduct electricity with a voltage of 35 kV to 230 kV. In the installation of the HV overhead transmission line tower structure, one of the main things that need to be considered is the installation of stub that can affect the sturdiness of the tower. This research aims to design and make a stub setting fixture on the HV overhead transmission tower installation. The research process began with data observation and literature study of tower stub installation in the 150kV 2xZebra Andolo – Kasipute Sec.1 installation project of PT. PLN Persero UIP South Sulawesi, then designed the stub setting fixture components, design data analysis, and fixture manufacturing. The results of the analysis of the design structure experienced do not exceed the limits of the material stresses of the component, the analysis of machine elements in the stub setting fixture is able to withstand the loads experienced by the component. It is expected that there will be improvements and development of fixture in the form of more efficient forms of construction and operation, and can use analog and digital controls in terms of fixture operation in subsequent development and research.
