Product Details:

Cord Winding Crack Tester for Wire and Cable TestThe cord winding crack tester is used to determine the bending performance of wires and cables at low temperatures. It is suitable for round wire and cable with outer diameter ≤12.5mm or round insulated core, and flat wire and cable with size ≤20mm or fan-shaped insulated core that cannot be made into dumbbells. The machine is an indispensable instrument in the wire and cable industry for the bending function test of products. The test standards be used for cord winding crack machine include: IEC 60811-1-4 JIS C 3005 2014 ISO 6722-1 ISO 6722 -2
Test Mothod for Cord Winding Crack Tester: The machine is specialized in testing the impact and bending of the variable wires under low-temperature condition. If the cross -sectional area of than 100mm², then specimen must be put into testing chamber for freezing for one hour, after that immediately rolls specimen aro specified rod in a uniform speed. Otherwise, for the cross – sectional area over 100mm², roll the specimen before hand and put in freezing one hour. Afterwards, immediately roll specimen around the rod in reverse direction. Finally, take out of specimen for check its surface has crack or fissure or not.
The cord winding crack tester produced by Wewon Tech is suitable for the bending performance test of power distribution and communication cables and optical cables, including the material changes of the polymer insulation and protective sheath materials of marine and offshore cables and optical cables after bending at different temperatures. The test standards frequently used by customers are: ISO 6722-1 and ISO 6722-2. ISO 6722 has two parts, Part 1 is the size, test methods and requirements of copper conductor wires, and Part 2 is the size, test methods and requirements of aluminum conductor wires.
