| Description LUTENE® XL2802BK is a cross-linkable semi-conductive shielding compound for conductor and bonded insulation shielding of high voltage power cables. LUTENE® XL2802BK is compatible with both copper and aluminum conductors. LUTENE® XL2802BK was specifically developed to provide a excellent-smoothness surface yielding a more perfect interface between extruded shield and the insulation. As a result, significantly improved cable performance can be expected. LUTENE® XL2802BK has stable volume resistivity characteristics at elevated temperature. Applications Excellent-smoothness extra clean semi-conductive compound for conductor and bonded insulation shielding of high voltage power cable Characteristics Excellent Surface Smoothness Excellent Electrical Properties Excellent Physical and Thermal Properties Long-run Extrusion without Scorch Specification LUTENE® XL2802BK meets the property requirement of the following material specifications.
