High Voltage (HV) Cables

Borlink™ XLPE insulation enhances network performance, reduces costs

As one response to current and future challenges in grid performance and supply reliability, underground cable networks have become increasingly viable alternatives to traditional overhead lines thanks to advances in technology and reductions in overall system costs. Borealis has developed the Borlink™ technology platform, a complete global package of power cable compounds and expertise with applications for HV, including extra high voltage (EHV) and high voltage direct current (HVDC). Based on our enhanced base resin technology (Supercure), Borlink insulation compounds are unique and innovative materials offering superior cleanliness essential for reliable high performance. For manufacturers, these compounds provide:

• Increased scorch safety during cable extrusion, lowering risk of insulation defects
• Long cable production runs
• Reduced degassing time burden optimising production, with 10-20% shorter production cycles possible and the subsequent reduction of associated capital costs.

And for system operators, Borlink HV solutions offer long-term reliability, overall safety and low-loss HVDC technology.

Cleanliness is key to top performance in the long term 

Our proprietary Borlink solutions based on XLPE insulation compounds and semiconductive inner and outer shield compounds have become the preferred compounds of choice for HV underground cables. They are cost effective, highly reliable, have low dielectric losses and low environmental impact.

To ensure cable system reliability, the use of high quality and clean XLPE compounds is essential to avoid reduction in insulation performance and even critical system failure. Borlink XLPE insulation compounds are produced in contamination-free environments according to a closed or controlled loop system and delivered in Borlink octabins filled under clean room conditions. This ensures the level of cleanliness required to achieve consistent and reliable long-term performance.

At higher electrical stresses, a smooth interface between insulation and shielding increases the potential of maintaining an uninterrupted power supply. Our Borlink semiconductive compounds have been optimised to provide the required smooth and even surfaces which eliminate surface pips, reduce electrical stresses and minimise the risk of power failure.

Leading global supplier with a proven track record

Our Borlink technology stands for reliability, continuity and security, and enables continuous innovation step-changes. Borlink serves as the platform to work together with the entire energy infrastructure value chain to establish innovative solutions that address the challenges of an increasingly connected world. By working together with Borealis, producers and operators enjoy access to high-quality and reliable solutions which help meet rising demand for electricity and facilitate rapid infrastructure growth. We have a unique and impressive industry track record spanning decades of operational experience in HV, EHV and HVDC, yet we never stop innovating. And by continually investing in state-of-the-art production facilities, we can maintain the consistently high production cleanliness levels which are required for the most demanding applications.
