High Voltage Cable Channel Work (SKTT) 150 kV or Underground High Voltage Cable works can be carried out using the Horizontal Directional Drilling (HDD) machine, in accordance with the State Electricity Company Standard (SPLN) T4.003:2023, and is commonly applied in urban areas with high traffic density. This article analyzes the failure of the High Density Polyethylene (HDPE) pipe pulling process in the 150 kV SKTT work at the MRT Jakarta Phase 2A Project, CP 205. The failure occurred due to a time delay of approximately 4 hours between the borehole cleaning process and the pulling operation. This condition resulted in the failure of pulling HDPE PN10 pipes with diameters of 6 inches and 4 inches. Corrective actions were conducted by reaming the original borehole using the same parameters. The pulling operation was then performed immediately after the cleaning process was completed. The evaluation results indicate that eliminating any time delay between the cleaning and pulling processes can prevent borehole collapse and ensure the successful installation of HDPE pipes in 150 kV SKTT works.
