| Borlink LE0500EHV is a Supersmooth ready-to-use semiconductive compound, specially designed for semiconductive conductor screen and bonded insulation screen of energy cables. Applications Borlink LE0500EHV is intended for semiconductive shielding of XLPE extra high voltage (EHV) cables. Specifications Borlink LE0500EHV meets the applicable requirements as below when processed using sound extrusion practice and testing procedure: AEIC CS9 ANSI/ICEA 108-720 EC 62067 Special Features Borlink LE0500EHV is a ready-to-use semiconductive compound. It offers excellent thermal stability which provides robust cable extrusion and crosslinking at high surface temperature. The excellent distribution of carbon black and additives in Borlink LE0500EHV results in superior smoothness of the semiconductive screen. Borlink LE0500EHV is intended as conductive shields in cables rated 400kV and above. The product is manufactured with the most stringent specification on smoothness reflected by a frequency of pips reduced by 50% compared to Borlink LE0500.&& |
