Borealis combines unique, high productivity with a longer lifetime for XLPE cables

Borealis is adding another grade to its SupercureTM high productivity energy cable compound product portfolio by offering a crosslinked polyethylene (XLPE) insulation solution for long-term performance cables. The first of its kind, Supercure LC8205 combines water tree retardant properties with faster crosslinking, ensuring longevity of the cable and quick production runs benefiting both cable makers and power distributors.

Michael Bjørn, Borealis’ Marketing Manager for the wire and cable business, says: “For both power distributors and their customers, the long service life of a cable system is essential to a reliable, cost-efficient electricity supply. Borealis is introducing a new, advanced insulation solution which not only allows cable manufacturers to deliver cables with high-performance over the long term, but which also offers them the ability to achieve better capacity utilisation thanks to faster and more cost-effective production runs.”

Supercure LC8205 is based on a combination of Borealis water tree retardant copolymer technology for medium voltage cables and the patented Supercure high-productivity technology. Supercure productivity enhancement technology ensures that LC8205 maintains the high level of cable quality whilst at the same time increasing cable plant productivity. Crosslinking occurs faster in the curing tube, allowing a 30 per cent increase in line speed. Reduced production costs result from the higher productivity.

The enhanced water tree retardant copolymer technology achieves outstanding results by reducing the growth of water trees thus extending cable lifetime. Supercure LC8205 is developed to meet industry standards for accelerated wet ageing, including Cenelec HD 620 (2000).

Borealis has more than 40 years of experience in providing high-quality polyolefin compounds to the wire and cable market and is the world leader in this market segment.
