Carbon Black is one of the most essential raw materials used in semi-conductive compounds to manufacture power cables for transportation of electric current. Carbon Black imparts electrical conductivity to both conductor shield and insulation shield. The semi-conductive layer in power cables facilitates homogeneous distribution of the electrical field, thus reducing the electrical stresses to the cable`s polymer components. This smoothing effect prevents the cable from local failure and guarantees long service life.
For black cable jacketing Carbon Black provides an excellent UV protection in all polymers.
