220kV LILO Jetpur–Sardargadh

Project Overview

The 220kV LILO Jetpur–Sardargadh project involved the complete Supply, Erection, Testing, and Commissioning of a 220kV LILO (Line-In Line-Out) of the 220kV S/C Jetpur–Sardargadh transmission line at the 220kV Shapur Substation. The work included construction on D/C and M/C towers using ACSR Zebra conductors and OPGW cable over a 6.20 km stretch. The project strengthened the regional transmission network and enhanced grid reliability under GETCO’s non-renewable transmission infrastructure program.

Scope of Work

  • Supply, erection, and stringing of 220kV transmission line on D/C & M/C towers.

  • Installation and integration of ACSR Zebra conductors for improved current carrying capacity.

  • Laying and commissioning of OPGW cable for communication and protection systems.

  • Construction of LILO arrangement at the 220kV Shapur Substation.

  • Complete testing, inspection, and commissioning as per GETCO standards.

  • Compliance with all safety, quality, and environmental guidelines.

Challenges

  • Complex tower erection in uneven and soil-variable terrain.

  • Ensuring uninterrupted grid operation during LILO integration.

  • Maintaining stringent safety protocols during high-voltage stringing.

  • Coordinating material movement and heavy equipment across narrow access routes.

  • Working under variable weather conditions affecting installation timelines.

Solution

  • Deployed a specialized team for precision tower erection and conductor stringing.

  • Used advanced tension stringing equipment to ensure safety and accuracy.
