SCHNEIDER ELECTRIC SM6 SYSTEM

Standardized Medium Voltage Panels under the SM6 brand name with the use of Schneider Electric electrical equipment, suitable for indoor use. SM6 type MV panels consist of modular cubicles, each of which may include:

  • Electrical equipment (switch disconnectors, circuit breakers, protection relays, fuse switch disconnectors), fixed or removable type, either in SF6 or vacuum (Evolis) compartment.
  • Prefabricated, metal-enclosed cubicles that use air as the dielectric means and include the above equipment. The SM6 series meet the requirements regarding the safety of the personnel, the installation, the proper operational sequence and environmental protection.

 

STANDARDS AND QUALITY CERTIFICATES

Both the cubicles and the equipment installed are designed, manufactured and tested according to the following standards:

  • General requirements for medium voltage panels – IEC 60 694
  • Metal enclosed Medium voltage panels – (1 in 52kV) IEC 62271-200
  • Medium Voltage Switching Devices – AC IEC 62271-103
  • Medium Voltage Disconnectors and Earthing Switches – IEC 62271-102
  • Medium Voltage Circuit Breakers – AC IEC 62271-100
  • Medium Voltage Relays – AC IEC 60 470
  • Medium Voltage Fuse Switch Disconnectors – IEC 62271-105
  • Current Transformer – IEC 60 044-1
  • Voltage Transformers – IEC 60 044-2
  • Current sensors – IEC 60 044-8
  • High voltage fuses – IEC 60 282-1
  • Medium Voltage Protection Relays – IEC 60 255
  • Electromagnetic compatibility for measuring and control equipment – IEC 60 801
  • Degree of protection (IP) – IEC 60 529

The quality system for the design and construction of the SM6 series cubicles is in line with the standards and requirements of the ISO 9001 quality regulations.
