As India continues to strengthen its regulatory framework for electrical and electronic equipment, the spotlight today is on a crucial category: High-voltage Switchgear and Control Gear Equipment (above 1000V)—now officially brought under the ambit of Bureau of Indian Standards Scheme X – Omnibus Technical Regulation (OTR).

These high-voltage systems are the backbone of power transmission and industrial infrastructure, responsible for managing, protecting, and controlling the flow of electricity in critical applications..

Scope of Regulation:

Covers all types of switchgear and control gear equipment operating above 1000V, including their assemblies, sub-assemblies, and components.

Examples Include:

  • Vacuum Circuit Breakers (VCBs)
  • Gas-Insulated Switchgear (GIS)
  • Air-Insulated Switchgear (AIS)
  • SF₆ Circuit Breakers
  • Oil Circuit Breakers (OCBs)
  • Disconnectors (HV/MV Isolators)
  • Load Break Switches (LBS)
  • Ring Main Units (RMUs)
  • Lightning Arresters – HV/MV
  • Instrument Transformers (CTs & PTs)

Applicable HSN Codes:

  • 8535
  • 8537
  • 8538

Compliance Deadline:

1st September 2026: Post this date, manufacturing, importing, or selling non-compliant products in India will be prohibited.

Note: This order excludes any product already covered under existing BIS QCOs.

This move underscores the government’s push for enhanced safety, performance, and reliability in high-voltage power systems—especially important for sectors like renewable energy, industrial automation, and smart infrastructure.
