Electrical Design

Introduction When designing high-voltage transmission lines, one of the most critical design parameters is the air gap clearance — the safe distance between energized conductors and grounded components such as tower arms or insulator fittings. For any transmission line, air gap clearance ensures system reliability, electrical insulation safety, and compliance with international standards.This article explains

Introduction The global energy landscape is rapidly shifting toward renewable sources such as solar, wind, and hydro. While this transition reduces carbon emissions, it introduces significant challenges for transmission line design. Engineers must now account for variable loads, voltage fluctuations, and new grid stability requirements. Proper planning ensures safe and efficient transmission networks for a
