In the early-1990s, we found that lightning protection and grounding device existed serious corrosion when using in the project in our country, and there has no systematic solution or serial products, so we began developing and the manufacturing anti-corrosive lightning protection and grounding device which take the composite metal material for main body. After more than 10 years’ research and applicant, the product of Green Electric sweep into all the serials in lightning protectionã€groundingã€fusion weldingã€surge protection and so on. These products have widely used in petrochemical industryã€electric powerã€railwayã€military industryã€aerospaceã€telecommunication aero and so on. We insist on pursuit eminent quality, continuously perfect quality control system and we create many NO.1 domestic at the same time.
