For lightning protection of distribution box transmission line, reasonable lightning protection methods shall be adopted through technical and economic comparison according to the voltage level, load nature and system operation mode of distribution box line, combined. For lightning protection of distribution box transmission line, reasonable lightning protection methods shall be adopted through technical and economic comparison according to the voltage level, load nature and system operation mode of distribution box line, combined. Our light-ning and surge voltage protection systems are per-fectly matched to one another and to the requirements in the different zones – from the air-termination device, which must arrest the full energy of a lightning strike, through to fine power protection, which eliminates the last voltage. This article is an overview of the challenges and opportunities we now face in the lightning protection of electric power distribution systems. Specific topics are lightning protection of underground circuits, overhead circuits, system equipment, and lines of all configurations. In terms of safety, we need to protect it. First, let's talk about the lightning protection design of distribution box transmission line: For lightning protection of distribution box transmission line, reasonable lightning protection methods. nVent Engineered Electrical & Fastening Solutions is a leading global manufacturer and marketer of superior engineered products for niche electrical, mechanical and concrete applications. These nVent products are sold globally under a variety of market-leading brands: nVent ERICO welded electrical. When designing lightning protection systems, various parameters must be taken into account.
