Test stations TU 3435-008-93719333-2012

43-2A test station consists of a 200X200 mm square-cross section post and a terminal block, fixed on it. Additionally completed with a distance mark, which allows controlling a pipeline route visually from the air.

A post is made of PVC. The applied materials are used outdoors in all the climatic zones. The post is equipped with an anchor device, which prevents a test station from free taking out.

A terminal block is made of polycarbonate and meant for setting up about 48 terminal clamps on one terminal board. Installation of 2 terminal boards is possible. The terminal clamps are made of stainless steel or yellow metal. To exclude an illegal access, the terminal block has a cap with a locking arrangement.

Marking and warning (informational) inscriptions are made ​​on a self-stick film by thermal transfer printing method. To increase the resistance of marking signs and labels to UV radiation, an outside lamination with a special protective film is applied. The resistance period is at least 15 years.

Construction advantages 

  • Increased resistance to the influence of environmental climatic factors
  • Modern and aesthetic appearance
  • Free access to the terminal block clamps
  • Easy cable and accessories (reference electrodes,  corrosion rate indicators etc.) installation
  • Equipment installation inside the post (join protection blocks, controllers etc)
  • additional maintenance to preserve the appearance is not required
  • low weight

A test station combined with a joint protection block JPB (R)

47The utilization of the power resistors allows to   make a smooth adjustment of channels resistance, not using electrical connectors and without disconnecting the cathodic protection station.

A built-in instrument shunt allows to determine the channel current rate using a millivolt meter.
