COPOLYMER MODIFIED XLPE FROM BOREALIS IMPROVES LIFE EXPECTANCY OF MV CABLES
21 June 2000 - Borealis A/S
| Degradation of polymeric insulation when subjected to wet conditions, known as water treeing, has been known since the early 1970's. The situation improved drastically by the introduction of extruded outer semiconductive layer, but still the concern for wet-ageing properties demanded for further development of the XLPE insulation material. In the early 1980s copolymer modified XLPE compounds were introduced by Borealis. The are blends of polyethylene homopolymer and specially selected acrylates. |

Long term experience from both laboratory tests and the field have proven the superior long-life performance of cables produced from those compounds. The compounds are available under the trade names LE4205 and LH4201 and both compounds comes in regular or superclean versions.
