UEBD50-Self-amalgamating semi-conductive tape
UEBD50 is EPR (ethylene propylene rubber) based
self-amalgamating semi-conductive tape.
It is void free and shelf stable, with stable
conductivity cover a wide temperature range. The
excellent stretch allows conformability to complex
shapes. It is compatible with all types of polymeric
insulated cable up to 132kV.
