Tensile test on cables and strands

Universal testing machine Inspekt table blue 20kN

Test system for tensile force tests on cables, cables with plugs, ferrules and cable lugs, which are installed in control cabinets. The test system consists ofUniversal testing machine Inspekt table blue 20 kN with two load cells (20 kN and 3 kN).Wrap-around clamping device TH170-50, 

a pair of wedge grips with clamping jaws for flat samples with saw tooth profile.

Cable pull-out test with clamping bell

The clamping bell has a diameter of 90mm and is rotatably mounted like a revolver, where the 8 clamping slots (from 1.5 to 25mm wide) are used to clamp the assembled cables. Furthermore there is a holding mandrel on the clamping bell with 3 steps (8, 12 and 16mm). This mandrel is used on cables with ring cable lug.  The tool is attached to the lower fixed crossbar by means of an adapter set from Hegewald & Peschke. On the opposite side, the cable is then clamped into the wedge clamping tool. A cable pull-out test is then carried out. This determines the required tensile force at which the cable is released from the respective connector. Alternatively, a creep test is carried out in which the plug is exposed to a specific time with a specific force.

Cable pull-out test with cable tensioner

The self-clamping cable tensioner is also used for cable pull-out tests, but only up to 3kN. Its clamping range is 0-20mm. A special feature of this test tool is that the two eccentric rollers adjust evenly under load, thereby increasing the clamping pressure.
