4. Izicelo zezingane ezi-33kv

Izinto ezifakiwe ezingama-33kv zisetshenziswa ezinhlobonhlobo zezimboni kanye nokusetha kwengqalasizinda:

• Izinsiza Zokusabalalisa Amandla: ukwehla kwehla ama-voltage amadolobhana namadolobhana
• Izikhungo Zokukhiqiza Ezikhulu
• Izimayini nezensimbi
• Ukuhlanganiswa kwamandla okuvuselelekayo: Ilanga, umoya, amapulazi a-hybrid
• Ukuthutha: Metro, Railways (Amandla weTraction)
• Izakhiwo Zentengiso: Izikhungo zedatha, izitolo zezitolo
