Product Overview

GDIT-SR derives its self-regulating characteristic from the inherent properties of the semi-conductive core material. As the core material temperature increases, the number of conductive paths in the core material decreases, thus decreasing the heat output. As the temperature decreases, the number of conductive paths increases, causing the heat output to increase. This occurs at every point along the cable’s length, adjusting the power output to the varying conditions. As the cable self-regulates its heat output, it limits the maximum sheath temperature, thus making it burn-out proof.
