Fire resistant control cable 2-4 cores 300/500V features Mica tape twisted with copper conductor, the cable refers as multiple cores Cu/MicaXLPE(PVC)/LSZH 300/500V to basic standard BS7211. The function of mica is to prevent burning when cables catching fire. The cable can maintain the integrity of the electric circuit and continue to work for a period of time when exposed to fire. The sheath is compound material LSFH low smoking free holagen which has little smoking and no toxic gas emission which reduces the damage to the people and equipment. Thesefire rated control cables we supplied are twisted two layers of mica tape with 80% overlap rate which achieves a good performance of fire resistance.
