Feature
Small resistance can make cable has semi-conductivity and weaken the electrical field strength effectively.
High mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.
It is heat-resistant and can bear high instant temperature.Cable with this product can keep stale 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.
