| Borlink LE8280 is a crosslinkable black polyethylene compound, specially designed for semiconductive conductor screen and bonded insulation screen of energy cables. Applications Borlink LE8280 is designed for semiconductive screens in XLPE medium and high voltage cables. It can be used as inner and outer screen for bonded cable constructions and as inner screen for strippable cable constructions. Specifications Borlink LE8280 meets the applicable requirements as below when processed using sound extrusion practices and testing procedures AEIC CS8 AEIC CS9 BS 6622 DIN VDE 0276-263 DIN VDE 0276-620 Cenelec HD 620 S1 Cenelec HD 632 S1 ICEA S-93-639 ICEA S-94-649 ICEA S-97-682 ICEA S-108-720 IEC 60502-2 IEC 60840 NF C33-223 NF C33-226 UTE C 33-223 Special Features Borlink LE8280 is a ready-to-use semiconductive compound. It offers excellent thermal stability which provides robust cable extrusion and crosslinking at high surface temperature, allowing for high line speed. It also provides excellent scorch resistance property. The excellent distribution of carbon black and additives in Borlink LE8280 results in a very smooth semiconductive screen.&& |
