Semiconductor water-resistant yarn also has excellent water-blocking properties. It can swell quickly after encountering water to form an effective water-blocking barrier. In addition, double side waterproof tape can also provide a certain buffering effect to protect the cable from mechanical damage.
Feature
- strong moisture absorption, big expansion rate and quick expansion velocity.
- Small resistance can make cable has semi-conductivity.
- Double side waterproof tape can buffer and weaken the electrical field strenath effectivelv.
- High mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.
- It is heat-resistant and can bear hich instant temperature.
- Cable with this product can keep stable performance.
Application
- lt used for the semi-conductive water-proof layer of the water-proof medium, high and extra high voltage cables;
- It also used for the control, communication, signaling and instruments;
- It is used for cables with shielding requirement.
