Project Overview and Challenges

The Raipur project involves reconductoring 132kV lines across plain terrain that covers about 90% of city areas, including multiple crossings over railways, national highways, state highways, and industrial feeders. The lines supply power to critical industrial plants and utilities, making reliability paramount. Challenges include:

• Navigating complex Right of Way (ROW) constraints in densely populated urban and industrial zones.
• Managing multiple crossings with railways and highways requiring precise planning and coordination.
• Upgrading aging infrastructure while minimising downtime to avoid disruption to industrial feeders.
• Operating in plain terrain with extensive urban coverage, which demands meticulous route planning and stakeholder management.

APAR’s Innovative Solution

APAR addressed these challenges by deploying its advanced HTLS ACCC conductors. ACCC conductors feature a composite core made of hybrid carbon and glass fibres, providing:

• Up to twice the current-carrying capacity of conventional conductors of similar size and weight.
• Lowest sag in the HTLS category due to a very low coefficient of thermal expansion, enabling operation at temperatures up to 180°C.
• Superior electrical conductivity and reduced resistance, resulting in lower transmission losses and improved energy efficiency.
• Enhanced mechanical strength and corrosion resistance, extending service life and reducing maintenance needs.

By using ACCC conductors, APAR enabled the existing transmission towers to carry more power without the need for costly new towers or line corridors.

Why ACCC HTLS Conductors Are a Game-Changer

Compared to traditional ACSR conductors, APAR’s ACCC conductors reduce sag and line losses substantially. They operate cooler, which improves efficiency and enhances grid reliability by allowing higher overload capacity to prevent cascading failures.
