Water Blocking Tape
1. Material: Plastic
2. Application: It is used for the semi-conductive water-proof layer of the water-proof medium, high and extra high voltage cables, also the control, communication, signaling and instruments cable swith shielding requirement.
3. Feature:
A. It has characteristics of strong moisture absorption, big expansion rate and quick expansion velocity.
B. Small resistance can make cable has semi-conductivity, and can buffer and weaken the electrical field strength effectively.
C. High mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.
D. It is heat-resistant and can bear high instant temperature. Cable with this product can keep stable performance at instant high temperature.
4. Storage: It should be stored in dry house, kept away from source of fire and not to be exposed to the sunshine. Also it should avoid moisture and mechanical damage during storage and transportation. The shelf life is 6 months after the manufacturing date.
