  • Certified for better thermal management as per IEC 61921
  • Design verified assemblies of both constructional & permanence

Requirements

Separate section for detuned reactors, capacitors & switchgear ensures longer life of components & less worry on maintenance

Safety

  • Form 3B separation (compartmentalized design for switchgear)
  • Bus bars with more clearance than prescribed in standards
  • A minimum of IP2X degree of protection even when the doors / covers in open condition
  • Earthing of each and every door and structural members

Zero stray voltage on doors & covers ensures both operator & equipment safety
