Description：
Products overview:
Shielding line is wrapped a layer of the outside of the conductor shielding layer, plays a role of anti-interference, general shield for the knitting of brass or copper (aluminum), shield grounding when use need, to foreign interference signal is the layer into the earth, and to avoid jamming signal into the inner conductor dry all at the same time reduce the wastage of the transmitted signal.Shielding line is fit for ac rated voltage up to and including 450/750 power electrical appliances, instrumentation and telecommunications equipment, etc.
This product standards: GB5023-85
