The flexing test apparatus is designed to meet the test requirements of IEC60245-2 clause 3.1 & figure 3.1 and IEC60227-1 clause 3.1 & figure 1, for verifying the mechanical strength of completed flexiable cables. The flexing test is applied to test the PVC insulated cables and rubber insluated cables with 2 or more cores, rated at voltage up and equal to 450V/750V.
The flexing test apparatus mainly consists of a carrier, a driving system for the carrier and four pulleys for each sample of cable to be tested. The carrier supports two pulleys A and B (have same diameter). The two fixed pulleys, at either end of the apparatus, may be of a different diameter from pulleys A and B, but all four pulleys shall be so arranged that the sample is horizontal between them.
