| Hanwha Wire & Cable Compound CLNA-8141EHV is a low density, crosslinkable polyethylene compound developed especially for the insulation of triple extruded XLPE power cables which employ high electrical stresses. It has an extremely low level of contamination and proper balance of non-staining antioxidant and peroxide to ensure thermal stability and optimum cure levels. Applications: CLNA-8141EHV is to be used as a crosslinked extra high voltage power cable insulation, i.e. above 161kV or for corresponding stresses (average working stress (based on Uo) < 12 kV/mm).&& |
