Description

777 (KC70) is a fire and electric arc proofing tape. It is designed to protect power  cables and terminations when exposed to potential failure in cable joints, by forming a thick char barrier between the flame and the cable. The resulting firewall acts as a heat shield and flame barrier, thus protecting the nearby cable and accessories. 777 has an excellent flame- retardant oxygen index and also has an outstanding self-fusion property that similar products worldwide don’t have.
