SCT 45 /15
Semi-conductive heat-shrinkable tubing
SCT 45/15 is a semi-conductive, heat-shrinkable tubing made of radiation cross-linked polyolefin, specially developed for use in medium-voltage and high-voltage cable accessories. It is used for electrical field control, for restoring external conductivity and for safe shielding in joint and termination applications.
