band box

In the cathodic protection system of the pipeline, the band box is generally used to connect the transformer rectifier cables to the anodes and pipes. Through the band box, it is possible to measure the potential of the pipeline with respect to the soil, the current of the pipeline, the stray current passing through the pipeline, the resistance of insulating connections, etc.

Bernagdas band boxes are made on demand from iron sheet with a thickness of 2 or 3 mm and in two sizes 150 x 200 x 400 and 150 x 300 x 380 mm with IP54.

Different parts and parts of band box are:

  • Four brass terminals with resin insulation base are used for the four-terminal band box and eight brass terminals with resin insulation base are used for the eight-terminal band box inside the box.
  • Two or three copper straps to connect the terminals to each other in the four-terminal band box and eight copper straps to connect the terminals to each other in the eight-terminal box band.
  • Two suitable hidden hinges are installed on the body. The hidden hinge increases the safety factor and prevents theft.
  • The nuts of the door-to-body mounting screws are of the Khoroski type.
  • A plastic strip is attached around the edge of the door, which guarantees IP54 waterproofing.
  • In order to install the base to the box, a plate with a thickness of 3 mm and dimensions of 125 x 300 mm is installed in the lower part of the box according to the standard with galvanized screws.

Test point

  • The potential of the pipeline relative to the soil can be measured through the test point. Bernagdaz test points are made in different types and based on order. The test point base is produced from iron pipe with a diameter of 75, 100 or 150 mm (according to request). The shade is made of iron sheet with a thickness of 2 or 3 millimeters.

The different parts and parts of Test Point are:

  • According to the request, 1, 2 or 4 brass terminals (suitable brass screws and nuts) are installed inside the test point.
  • For proper installation inside the concrete foundation, three iron rods are placed as prongs at the bottom of the base.
  • For convenient and convenient cable entry and exit, a suitable hole is installed at the bottom of the iron pipe base.

Marker

  • A marker is used to show the route of the pipeline and the initial and final location of the cathodic protection bed. The marker base is made of iron pipe with a diameter of 75, 100 or 150 mm (according to request). The shade is also made of iron sheet with a thickness of 2 or 3 millimeters.
سازه های فلزی

According to the request, Bornagodaz Company can use the following methods as cover or color of band box, test point and markers:

  • hot galvanized
  • All kinds of paints for furnaces with phosphate or chromate substrate
  • Special epoxy or alkyd paints with sandblasting
