20/07/2022 – Repsol chooses Buss “LSHC” technology

High-purity XLPE cable compounds

Buss AG has been awarded a contract for the realisation of a 27kta production plant for crosslinkable polyethylene XLPE cable compounds by Repsol. The global multi-energy company provides a wide range of solutions for different types of cables.

The new, patented “LSHC” process („Linear Short Hyper Clean“) has been developed by Buss AG in close cooperation with P+M Cable Consulting LLC, a Swiss based consulting firm in the field of cable compounds. It offers access to, among others, various High Voltage (HV) and Extra High Voltage (EHV) insulation materials, exhibiting superior product quality and process efficiency compared to the well-known soaking technology. XLPE grades for both, alternating (AC) or direct current (DC) cable applications are readily produced with this innovative and flexible process.

The “LSHC” technology relies on direct peroxide injection and gentle compounding of a newly developed additive cocktail by using Buss state-of-the-art “Compeo” co-kneader series, allowing at the same time for significantly reduced capital expenses and clean room requirements. Further advantages are the compact plant design without high-rise soaking tower and improved cleanliness and physical-electrical properties of the produced materials.

Buss AG is proud to work with Repsol on the realisation of this first-of-its-kind industrial production plant and will eagerly continue the excellent collaboration towards the scheduled start-up in mid-2024. The “LSHC” technology is available to Buss customers world-wide on the basis of a competitive licensing model. A corresponding pilot plant for production of HV and EHV materials will be available around the end of this year at the Buss Campus in Pratteln, Switzerland.
