Borlink LE8280 is a crosslinkable black polyethylene compound, specially designed for semiconductive conductor screen and bonded insulation screen of power cables.
Applications
Borlink LE8280 is intended for semiconductive screen of XLPE high voltage (HV) AC cables with rated voltages up to 230 kV (Um = 245 kV). It can be used as conductor and insulation screen for bonded cable constructions and as conductor screen for strippable cable constructions.
The values are voltages between phases as defined in IEC 60183.
Specifications
Borlink LE8280 is expected to meet the applicable requirements included in the below mentioned standards provided it is processed using sound material handling, extrusion and crosslinking practices as well as appropriate testing procedures. This applies up to the maximum recommended voltage level indicated in "Applications" section above since some standards cover wider voltage ranges.
IEC 62067 IEC 60840 AEIC CS9 (below 8 kV/mm) AEIC CS8 ANSI/ICEA S-108-720 ANSI/ICEA S-93-639 ANSI/ICEA S-94-649 ANSI/ICEA S-97-682 DIN VDE 0276-620 DIN VDE 0276-632 Cenelec HD 620 S2 (Part 1) Cenelec HD 632 S1 NF C33-226 UL 1072
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.
