Product No: LS-B40
The LS-B40 Low Temperature Tensile Testing Machine is a specialized device designed for testing the low-temperature tensile properties of cable insulation and sheathing. This equipment requires the use of a low-temperature environment apparatus. Prepared specimens are held in place by specific clamps, and tensile force is applied to the specimens at a stable tensile speed. Key indicators such as elongation of the specimens under low-temperature conditions are measured to evaluate the tensile resistance of cable insulation and sheathing materials in low-temperature environments, ensuring that the tested materials and related cable products meet the corresponding technical specifications.
