Electrical Features:
Semi-conductive water blocking tape with high moisture, large expansion rate, and fast expansion rate features. Low resistance, with semi-conducting characteristics, can weaken the electric field strength effectively. Not deformed easily when in external force, used for wrapping of all kinds of power cables. Good heat resistant, high temperature resistance in short-term, cable can keep stable at high temperature.
Slitting and packaging:
Slitting minimum width is 5mm, bore sizes are 52mm or 76mm; the winding maximum outer diameter is 800mm, carton packaging.
