1 Cable for underground power distribution and subtransmission. Description Application Underground power distribution and subtransmission. As transformer feeders in substations. In power plants, industrial and operation installations, in residential areas and mining installations, in dry or wet locations. Construction 1. : Copper, class Inner semi-conductor: Extruded. 3. Insulation: linked polyethylene XLPE. 4. External semi-conductor: Extruded strippable. These last three components extruded CV (continuous vulcanization) triple extrusion. 5. Screen: Copper tapes. 6. Outer : Compound polyvinyl chloride PVC. Main characteristics of 90ºC for normal operation, 130 C for emergency overload and 250 C for short circuit conditions. Excellent properties against heat aging. to abrasion, moisture and sunlight. Adequate resistance to greases and oils.. Gauge: From 50 mm² up to 630 mm². Marking: INDECO S.A. Section Packing: Non returnable wooden reels. Colour: Insulation: Natural. Outer : Red.
