TR CNCV-W
TR CNCV-W is a KS / KEPCO type names (Korea) cable designation: TR = TR: tree-retardant XLPE insulation (TR-XLPE); CN = CN: concentric neutral, copper wires laid round the insulated core; C = C: cross-linked polyethylene (XLPE) insulation; V = V: PVC (vinyl) sheath; -W = -W: water-blocking tapes (semiconducting and non-conducting) under the sheath; TR CNCV-W = TR CNCV-W: CNCV-W with tree-retardant XLPE insulation. 22.9 kV-y (Taihan p.25). KEPCO standard.
