buffering semi-conductive water blocking tape
1.strong moisture absorption
2.big expansion rate
3.quick expansion velocity
Buffering semi-conductive water blocking tape is used for water-proof layer inside the metal sheath of high or extra high voltage cable.
Specification and technical parameter is as follows:
|expansion velocity (mm/1st min)||≥8||≥8||≥8||≥8|
1,it has characteristic of strong moisture absorption,big expansion rate and quick expansion velocity.
2,small resistance can make cable has semi-conductivity and weaken the electrical field strength effectively.
3,high mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.
4,it is heat-resistant and can bear high instant temperature.cable with this product can keep stable performance at instant high temperature.
it should be stored in dry house,kept away from source of fire and not to be exposed to the sunshine.the shelf life is 6 months after the manufacturing date.also it should avoid moisture and mechanical damage during storage and transportation.
