Description
Single Semi-Conductive Water Blocking Tape is made of a single layer of semi-conductive polyester fiber non-woven fabric and high-speed expansion water-absorbing resin. The semi-conductive base layer is manufactured by evenly distributing the semi-conductive compound on the base cloth.
Widely used in used in power cables of various voltage levels.
Characteristics
• Strong hygroscopicity, fast expansion rate
• Small surface resistance and volume resistivity
• Good mechanical strength, heat resistance
