1. Products with my company's zinc sacrificial anode (abbreviation: zinc ribbon) comply with ASTM-B418 (Type 1 / Type 2) standard, mainly used to protect the casing pipe, pipeline cathodic protection temporarily, tank and pipe network of protection against the strong current line of buried pipelines AC interference and lightning interference. Requires no external power supply, there is a continuous strip of conductive core, electrical connection and less. You can do a ground pole, release exchanges, lightning, protective equipment and personal safety. 2.
