The client is a professional enterprise engaged in the research and production of power cables, control cables, and special cables. The products are widely used in urban and rural power grid renovation, building distribution, and communication network construction. In recent years, with the increasingly strict quality supervision of wire and cable products by the country (such as CCC certification and continuous strengthening of production license rules), customers need to conduct more refined tensile performance testing on their products.
Equipment solution: 10 ton electronic driven horizontal machine
1. Horizontal structure, easy to handle ultra long cables
The equipment adopts a horizontal frame structure, and the effective stretching space can be customized according to customer needs, fully meeting the full-size testing requirements of ultra long samples such as power cables, steel strands, optical cables, and ropes. The experimental space adopts a horizontal split design, combined with a track type mobile car or lifting platform, allowing one person to easily complete the clamping and alignment of a 10 meter long cable, completely bidding farewell to the history of vertical machines requiring ladder operation.
2. High precision fully closed-loop control, accurate and reliable test data
Transmission system: Adopting imported AC servo motors and high-precision ball screw pairs, the transmission is smooth, the noise is low, and the speed is infinitely variable.
Force measurement system: Equipped with high-precision spoke type load sensors, the test force indication accuracy is better than ± 0.5% (0.5 level), and the effective measurement range covers 0.4% -100% FS. Whether it is a thin copper wire or a thick power cable, it can accurately capture the fracture point.
Deformation measurement: It can be paired with a large deformation extensometer or an electronic extensometer to accurately measure the elongation of cable insulation sheaths and the tensile strength of conductors.
3. Intelligent software system, one click generation of quality inspection report
TestMaster measurement and control software based on the Windows platform, supporting standard database management. The operator selects the "Cable Stretching" test plan, inputs the model and specifications, and the equipment automatically adjusts the return speed to start the test with one click. The software can draw real-time force displacement/force time curves and automatically calculate key indicators such as tensile strength, elongation at break, and yield strength. Automatic storage of test data, support for historical traceability, and one click export of formatted test reports that comply with GB/T2951 (Mechanical Performance Standards for Cable Insulation).
4. Special fixtures, reliable clamping without slipping
Jinan Xinguang can be equipped with various specialized fixtures to address the smooth and slippery surface of cable and rope samples
Cable specific wedge-shaped fixture: As the tension increases, the clamping force synchronously increases, effectively preventing cable slippage.
Corrugated board/toothed fixture: suitable for polymer materials such as rubber and plastic.
Winding wheel fixture: for steel wire ropes or ropes, to prevent stress concentration from causing wire breakage.
Applicable industries and scenarios
Power industry: Tensile and fracture elongation testing of power cables and control cables.
Communication industry: Tensile strength and strain testing of optical cables and fiber optic cables.
Rope industry: testing the breaking force of climbing ropes, safety ropes, and trailer ropes.
Tensile testing of polymer materials: wide rubber sheets, waterproofing membranes, and geotextiles.
Medical devices: tensile properties of sutures, catheters, and elastic bandages.
