Surge arrester should be through its own fixed arrestor mounting bracket above the nut, surge arresters are usually installed above the pulse host, each zone the installation II surge arresters, installed in two ways. Independent electronic fence A freestanding electronic fences, installed at a distance of about 1 m Strip on the inside of the wall. Due to its height of 1.8M to 2.4m, alloy thread of 12-20 line, so wires on the Terminal poles and metal-bearing bar of tension, so, Terminal and metal-bearing bar must have sufficient strength, Terminal and metal-bearing bar laid must be stable. If the soil solid, direct Terminal poles and buried at the lower end of the metal-bearing bar 600mm as stationary. If the Terminal poles and metal-bearing rods stiff enough, support should be increased. Maximum distance between the Terminal 100m. B intermediate bearing rods, does not bear the tension of wire, but must support multiple line pressure and, therefore, also needs to be installed so solid. Embedding the installation can be used. Middle distance between the bearing Rod = 5M.
