Parallel Groove Clamp Market to Reach USD 2.15 Billion by 2032 at 4.39% CAGR | Power Distribution, Grid Modernization Drive Demand

The Parallel Groove Clamp Market plays a fundamental role in building resilient, efficient, and future-ready power systems. With the shift toward smart grids, renewable integration, and aging infrastructure upgrades, PG clamps are vital components in the global energy transformation.
Published 15 July 2025

The Parallel Groove Clamp Market is gaining momentum amid rising electricity demand, aging power infrastructure, and increased investments in smart grid modernization. Used extensively in overhead transmission lines, parallel groove (PG) clamps ensure strong mechanical and electrical contact between conductors. The global market, valued at USD 1.52 billion in 2024, is projected to grow to USD 2.15 billion by 2032, exhibiting a CAGR of 4.39% during the forecast period (2024–2032).

As utility providers aim to reduce power losses and improve grid reliability, the role of PG clamps in enhancing conductivity and system stability is more crucial than ever.

Key Market Drivers

  • Increasing Electricity Demand- Global energy consumption is on the rise, driven by urbanization, electrification of transport, and rising living standards—driving demand for robust transmission infrastructure and components like PG clamps.
  • Smart Grid Deployment- The integration of digital technologies into power grids calls for upgraded hardware. PG clamps facilitate connectivity upgrades for real-time monitoring and energy efficiency improvements.
  • Aging Infrastructure Replacement- Many countries, especially in North America and Europe, are replacing or retrofitting aging power infrastructure, increasing the use of new-generation clamps with superior conductivity and durability.
  • Renewable Energy Expansion- As renewable energy sources are increasingly integrated into national grids, PG clamps are used in new installations and substations to maintain stable and efficient energy transfer.
