Detail


General
Mullet core 3X120+1X70 sq. mm aluminium twisted conductor including a messenger wire, as specified below are require for high voltage distribution systems.

Applicable Standard
Performance, design, manufacture, installation and testing cables shall be in accordance to the latest revisions of IEC 502, 540, 227 or equivalent standards unless otherwise specific herein.

Description
XLPE Insulated overhead conductor consisting of three phase conductors and suspension unit; phase conductors with insulation of cross linked polyethylene (XLPE), copper screen & PE outer sheath suitable for outdoor use.

They may be used in all A.C single phase and three phase neutral earthed systems, resonant earthed or isolated neutral systems if a single phase to earth fault does not last longer than 8 hours and the total sum of all earth faults does not exceed 125 hours per year.

Highest continuous operating voltage Um = 12KV (Line to Line), and (a) both phase conductors isolated 12KV and (b) one phase conductor earthed 7KV.
