Electrical components aren’t just defined by their conductivity or insulation—they must also withstand mechanical stress. For components like insulators and electrical connections, mechanical strength is critical, particularly for insulators used outdoors where weathering and aging can reduce their load-bearing capacity over time. Accurate evaluation of these effects is essential to ensure safety, reliability, and performance.
The ZM 400 Horizontal Tensile Testing Machine, developed by FORM+TEST for Bayernwerk Netz GmbH, offers a versatile and reliable solution for testing a wide range of electrical components and materials. Designed to deliver precise, reproducible results, it accommodates everything from the smallest to the largest specimens, and from minimal to high load forces.
