High Voltage Cables
High-voltage cables are single-core cables. High-voltage cables are composed of conductors, insulation, shielding layers, armor layers and sheaths. Underground high-voltage cables with a rated voltage of 66kv and above are made of high-voltage cross-linked insulation and corrugated aluminum sheaths.
Conductor
Conductor consists of stranded soft drawn wires wounded together, and it could have one of the following two shapes:
1.Circular compacted conductor for CSA up to and including 800 mm2
2.Segmental conductor consists of 5 segments for CSA over than 800 mm2
Water tight conductors
Upon request, the conductor may be water tight by using swelling powder, yarns, tapes inside it(between conductor layers).
Conductor screen:
It is an extruded thermoset semi-conducting compound to minimize the concentration of elctric stress at any points on the conductor surface due to the stranding. Semi-conductive tape may be used before the conductor screen (it will be water blocked in case of water tight conductor).
Insulation
The insulation material is an extruded and dry cured cross-linked polyethylene (XLPE), and it is the cable electrical protection. The insulation should withstand the rated voltage, lightning over voltages and switching over voltage during its lifetime. The insulation material is capable to withstand 90℃ during normal operation and 250℃ during short circuit conditions.
Insulation Screen
It is an extruded thermoset semi-conducting compound over the insulation.
The three previous layers (conductor screen, insulation & insulation screen) are extruded simultaneously in one process and it is carried out on the CV lines with many measurements devices to control this process perfectly.
Metallic screen
This layer is the short circuit current carrying component and it may be one of the following type:
1. Copper wires with open helix copper tape as a binder
2. Lead alloy sheath
3. Combination of the previous
Outer jacket
This is the final prtection layer for all inside layers, and it may be one of the following types:
1. PE material (HDPE, LLDPE, MDPE)
2. PVC material
Semi-conductive layer
A semi-conductive layer to be applied over the outer jacket for jacket field testing after installation and this layer may be graphite powder or extruded semi-conductive layer.
