| Description LUTENE® XL2808BK TR is specially designed cross-linkable semi-conductive compound for conductor shielding of medium voltage power cables. LUTENE® XL2808BK TR is compatible with both copper and aluminum conductors. LUTENE® XL2808BK TR was specifically developed to provide an 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® XL2808BK TR is recommended for use in conjunction with XL8080NTS (Cross-linked polyethylene compound) and XL8080TR (Tree-retardant cross-linked polyethylene compound) Applications Cross-linkable semi-conductive compound for conductor and bonded insulation shielding of medium voltage power cables with rated voltage up to 35kV Characteristics Excellent Surface Smoothness Excellent Electrical Properties Excellent Physical and Thermal Properties Long-run Extrusion without Scorch Specification LUTENE® XL2808BK TR meets the property requirement of the following material specifications.
