6.35/11(12)kV three core copper XLPE Insulated galvanized steel tape armoured cables
Cable Construction
The 11kV XLPE Insulated Copper Cable has stranded compacted round copper conductor, conductor screening with extruded semi conducting thermosetting compound, with completely gas cured XLPE insulation, adequate insulation screening consisting of extruded semi conducting thermosetting compound layer, sheathed with Copper tape, inner jacket with Polyvinyl Chloride (PVC), armoured with Double flat galvanized steel tape and overall extruded termite repellent black HDPE or MDPE sheathed with outer conducting layer.
Conductor
The conductor is stranded compacted round copper conductor complying the requirement of flexibility Class-2 of IEC 60 228. The wires are made of high conductivity copper and stranded mid compacted. The copper used for the conductor is of highest purity.
Conductor Screen
The conductor screen consists of an extruded layer of thermosetting semi conducting compound and continuous and cover the whole surface of the conductor. The screen is firmly bonded to XLPE insulation.
A non-hygroscopic semi conducting tape may be applied over the conductor surface under extruded layer. The outer surface of the conductor screen shall be circular and free from irregularities.
Insulation
The insulation is cross-linked polyethylene (XLPE). The insulation material complies with the requirement as per IEC
60 502-2. The insulation is applied by extrusion and vulcanisation to form a compact homogenous body free from micro voids and contaminants.
Insulation Screen
The insulation screen consists of an extruded layer of thermosetting semi conducting compound and shall be continuous and cover the whole surface area of insulation. It shall be firmly bonded to the insulation.
Metal Sheath
The metallic sheath shall be of Copper tape applied helically.
Inner Jacket
The inner jacket consists of Poly Vinyl Chloride. The properties of inner jacket material shall be as per IEC 60 840.
Armour
The armour shall be of Double flat galvanized steel tape.
Outer Covering
The outer jacket consists of an extruded layer of black medium or high-density polyethylene. The outer jacket shall be of sufficient hardness to discourage termite attacks. The properties of outer jacket material shall be as per IEC 60 840.
