Test station is a 200X200 mm square-cross section post and a terminal block, fixed on it. Additionally completed with a distance mark, which allows to check visually a pipeline route from the air.
Post
A post is made of PVC. The applied materials are intended for outdoors operation in all climatic zones. The post is equipped with an anchor device which prevents test station from free taking out.A terminal block
A terminal block is made of polycarbonate and intended for applying up to 44 terminal clamps on one panel. Installation of two terminal panels are allowed. 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 device.Marking and warning (informational) inscriptions
Marking and warning (informational) inscriptions are made on a self-stick film by thermal transfer printing method. To increase the UV radiation resistance of marking signs and labels, an outside lamination with a special protective film is applied. The resistance period of marking and inscriptions is at least 15 years.Test station legend
