Kenya OEM context

From CTCN-SF6-KEN inventory.

  • Crompton Greaves, Siemens, Schneider, and ABB are the main CB manufacturers found in Kenya's grid
  • EU F-gas regulation bans new SF6 in MV equipment (<24 kV) from January 2026
  • SF6-free MV alternatives use vacuum, clean air, or solid dielectric insulation
  • HV transitional products use fluoronitrile or low-GWP gas mixtures (not fully SF6-free)
