This Semiconductive XLPE Shield Compound is a specially formulated cable manufacturing compound designed for the production of reliable Medium Voltage (MV) and High Voltage Power Cables up to 35kV. As an essential component, it forms the smooth inner semiconductor shield and insulation shield layers in XLPE insulated cables, ensuring uniform electrical field distribution and preventing harmful partial discharges.
The compound is a crosslinkable semicon based on a conductive polymer compound with optimized carbon black dispersion. It provides excellent compatibility with TR-XLPE insulation, creating a flawless interface that minimizes contamination and enhances the long-term performance of underground, industrial, and substation cables. Manufactured to meet stringent international standards such as IEC 60502-2, it is the ideal choice for producing durable and efficient power cable shields.
