IEC 60245-2 Two-Wheel And Three-Wheel Flexing Testing Machine For Cables Strength Test
Product Infromation:
Standard: IEC60245-1-2008 ”Rubber insulated cables - Rated voltages up to and including 450/750 V - Part 1: General requirements” clause 5.6.3.1
IEC60245-2-1998” Rubber insulated cables - Rated voltages up to and including 450/750 V - Part 2: Test methods” clause 3.1 and figure 1, clause 3.5 and figure 6
IEC60227-1:2007 ”Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 V - Part 1: General requirements” clause 5.6.3.1
IEC60227-2:2003 ”Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 V - Part 2: Test methods” clause 3.1 and figure 1
Specimen and limitations: Finished flexible cables, TUV, VDE, UL and other highly flexible cables.
Test purpose: It is used for bending mechanical strength test of finished flexible cables. This test is not applicable to cables with more than two concentric layers whose nominal conductor cross-section exceeds 18 cores.
Test principle: The 5m long sample moves back and forth within a 1m stroke through a pair of pulleys to achieve the bending test of wires and cables. By switching the two- and three-wheel clamps and adjusting the running speed, the two-wheel and three-wheel bending tests of cable samples can be achieved.
