Global leading cable manufacturer Riyadh Cables has recently opened power transmission and distribution market opportunities, by investing in new production and testing facilities for Extra High Voltage cable systems.

Riyadh Cables has signed a technology know-how transfer agreement with Brugg Cables, to start producing two new 400 kV EHV cable systems, conforming with specifications set by Riyadh Cables’ client Saudi Electricity Company.

KEMA Laboratories in the Netherlands completed the System and PQ tests as per IEC 62067 standard for power cables with extruded insulation and their accessories for rated voltages above 150 kV and up to 500 kV.

The two 400kV systems included two joints, one directly buried and the other installed in a tunnel; two SF6 terminations, one plug-in dry type, and the other a wet type; and two outdoor terminations. All of the accessories were nearly identical for both systems.

The two cables, installed in series, were both 2500 mm2 however the cable construction varied with different sized insulation thickness, metallic screening and outer sheathing.
