FIELD: the invention refers to testing technique particularly to testing equipment and control of electrical strength of the insulation of cable products.
SUBSTANCE: for achieving this result the stand has additionally a source of pressure, a sensor of pressure recording and an incoming-expending capacity with working medium for providing increase of pressure. At that the test unit in quality of a vessel with aggressive medium has a capacity limited from the faces with locking means and a high pressure chamber. The chamber is a vessel with an inner cavity filled with indicated aggressive medium. In quality of one or simultaneously both locking means the chamber has an insulating unit fulfilled in the shape of a clamping element and an insulating stuffing box installed with possibility of their interaction.
EFFECT: increases accuracy and reliability of tests.
