IEC 60245-2 Figure 6 Three-Wheel Flexing Test Machine Rubber Cable Bending Tester
Product Overview:
The SN2305 Three-Wheel Flexing Test Machine is designed to evaluate the mechanical strength and bending endurance of finished flexible cables.
It complies with IEC 60245-2 and GB/T 5013.2 standards, ensuring reliable and repeatable test results.
This machine is ideal for testing laboratories, cable manufacturers, and certification bodies that require high-precision rubber cable flexing tests.
Compliant Standards:
GB/T 5013.2-2008, Rubber insulated cables rated voltage 450/750V and below – Part 2: Test methods, Clause 3.5 and Figure 6
IEC 60245-2:1998, Rubber insulated cables – Rated voltages up to and including 450/750V – Part 2: Test methods, Clause 3.5 and Figure 6
Application and Principle:
The tester is used to assess the bending resistance and electrical reliability of finished flexible cables.
A 5-meter cable sample moves reciprocally over two pulleys within a 1-meter stroke, simulating repeated flexing stress.
During 1,000 reciprocating cycles (2,000 single strokes), the cable is continuously monitored to ensure:
No conductor breakage
No short circuit between conductors
No short circuit between the cable and pulleys
Features:
Servo-controlled drive for stable and quiet operation
Presettable speed and test cycles with automatic stop function
Real-time fault detection for open and short circuits
Heavy-duty frame ensuring durability and easy maintenance
Compact design suitable for laboratory environments
