12.7/22 kV SANS Type 622 / 622-ECC Cable Standard

SANS 1520-2, SANS 1411-1, SANS 1411-3

12.7/22 kV SANS Type 622 / 622-ECC Cable Feature

Voltage Rating: Specifically designed for medium-voltage (MV) distribution networks (typically suitable for 11kV or 22kV systems).
Installation Method: Suitable for fixed installation in trenches, conduits, or cable trays, or direct burial underground. Not suitable for environments with frequent bending.
Armored Construction: Suitable for environments requiring mechanical protection.
ECC Advantage: Integrated ECC simplifies installation (eliminating the need for separate grounding wires in most cases) while ensuring secure and reliable grounding connections. Particularly effective in single-core applications, it efficiently manages electromagnetic effects generated by the armored layer.
