Flex Tester Machine For Wires Two-Wheel/Three-Wheel

1. Scope of application:

1.1 Two-wheel flexure test: After 15,000 reciprocating movements of the flexible cable used to detect rubber insulation and sheath, that is, 30,000 single-way movements, neither current interruption nor short circuit between conductors should occur. Three-wheel flexure test: During 1000 times of reciprocating movement, that is, 2000 times of one-way movement, there should be no open circuit of the conductor, no short circuit between the conductors, and no short circuit between the cable and the pulley (test equipment).

2. Compliant standards:

2.1 Meet the standard requirements of Section 3.1 of GB/T 5023.2-2008, Section 3.1 and Section 3.5 of GB/T 5013.2-2008 and UL 1581.
