Because of the installation of transformer rectifiers outside power distribution buildings or the use of multiple transformer rectifiers in a station, AC boxes are used to divide and protect the input power of transformer rectifiers. The AC boxes have two types of single phase and three phases. These boxes usually have a main switch, inlet and outlet terminals, ground, signal light, protective fuses and more. The body of the AC boxes is made of 2 or 3 mm thick sheet steel.
In pipelines cathodic protection systems, bond boxes are generally used to connect transformer rectifiers cables to anodes and pipes. The potential of the pipeline to the soil, pipeline current, stray crossing current, insulation resistance, etc. can be measured through the box band.
The potential of the pipeline to the soil can be measured through the Point Test. Test points are made in a variety of types and on an order basis. The marker base is made of iron pipe 75, 100 or 150 mm in diameter (on request). Their shades are also made of 2 or 3 mm thick steel sheet.
A marker is used to indicate the path of the pipeline and the cathodic protection bed at the beginning and end. The marker base is made of iron pipe 75, 100 or 150 mm in diameter (on request). Their shades are also made of 2 or 3 mm thick steel sheet.
