Feature:

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.

Storage:

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.
