Power Transmission

Power Transmission

From 33 kV rural feeders to 400 kV EHV backbones, Aravinda Infra delivers end-to-end transmission EPC — survey, design, erection, and energisation — across every terrain and project scale.

Full EPC capability across 33 kV to 400 kV: transmission lines, EHV substations, and grid connectivity — delivered to PGCIL, TRANSCO, and state utility standards.

Transmission Lines — 33 kV to 400 kV

We manage the complete line project lifecycle — route surveys, tower erection, conductor stringing, and final energisation — with proven experience across hills, rivers, and urban corridors.

Key Capabilities

  • Survey & Route Optimisation - Topographical surveys, LiDAR alignment studies, and geo-tech investigations for optimal corridor selection.
  • Tower Design, Supply & Erection - Lattice steel towers for single and multi-circuit lines; mechanised and manual erection by certified climbing crews.
  • Conductor Stringing & Hardware - ACSR, HTLS, and ACCC conductors; tension and compression hardware; vibration damper installation.
  • Pre-Commissioning & Energisation - Insulator testing, live-line proximity protocols, and grid energisation coordination with STU/CTU
Substation Scope
Substation Development up to 400 kV

From civil foundations to relay programming and energisation — we execute AIS, GIS, and hybrid substations for state utilities, PSUs, and private industrial clients to PGCIL and TRANSCO specifications.

  • Civil & Bay Equipment — Control room buildings, earthing grids, power transformers, CTs, PTs, circuit breakers, isolators, and surge arrestors.
  • Protection & Control Systems — Numerical relay panels, SCADA integration, intertripping schemes, and station automation.
  • GIS & Hybrid Substations — Compact SF6 or eco-friendly GIS switchgear for space-constrained urban and industrial locations.
Grid Connectivity Services
Grid Connectivity & Related Infrastructure

We provide complete grid connectivity solutions — line tapping, bay extensions, pooling substation development, and SLDC/RLDC coordination — for ISTS, state utilities, and renewable IPPs.

  • Line Tapping & Bay Extension — Expanding existing substations for new generation or load feeders with minimal outage impact.
  • Pooling Substation Development — Multi-incoming-bay pooling substations with SLDC-compliant metering and grid connectivity.
  • Protection Coordination Studies — Load flow, fault level, and relay coordination studies for stable post-interconnection grid operation.
