KE Askari-VI 132/11kV Grid & T-Line Network Consultancy

Project Overview

The K-Electric Askari-VI 132/11kV Grid and Transmission Line project is a grid reinforcement initiative in Karachi, Sindh, Pakistan. Designed to support growing industrial and residential loads, the project involves constructing a new Gas-Insulated Substation (GIS) at Askari-VI.   It also includes high-voltage line bay extensions at KDA and Memongoth, LILO configurations, and the structural rehabilitation of existing transmission lines. Upgrading these circuits increases conductor current-carrying capacity, minimizes high-temperature line sag, and improves mechanical reliability under peak operating conditions.

Project Specifications

• Substation Rating: New 132/11kV Askari-VI Gas-Insulated Substation (GIS) grid station.
• Interconnection Scope: Encompasses line bay extensions at KDA and Memongoth substations, transmission line LILO works, and transmission circuit rehabilitation.
• Physical Infrastructure: Electrical layout designed to support local residential grids, including a 630 KVA kiosk and multiple sub-stations within Army Housing Askari VI.
• Safety & Quality Management: Project subject to formal Environment, Health, Safety, and Quality (EHSQ) risk assessments and EHS training programs.
