automaticfor chainsfor cables

Name of machine: Horizontal tensile testing machine Type of test: - Mechanical tensile strength test - Mechanical compression strength test Testing subject: - Electrical high voltage insulators - Chains - Electrical power fittings (line accessory) - Cable / Wires Standard applied for test of insulator: GB/T1001.1—2003 OH line insulator with nominal voltage over 1000 V HV insulators applicable: - Composite insulator - Porcelain insulator - Glass insulator Tests applicable for insulators: - routine test (FAT test) - type test - sample test This equipment is designed to perform mechanical property tests of various types of steel wires,cables,chains,electrical devices,insulators and insulating materials,it's also available for mechanical property tests on other specimen with long shape. Tensile test for insulator is one of the most important test in electrical standard for overhead line insulators. This tensile testing machine for log rod insulator is powered by hydraulic motor with high precision and controlled automatically by computer,which make it possible to be both stable, precise,flexible and effective in performing the tests. According to requirements in insulator standard IEC and ANSI, the string insulator shall be qualified to bear designed mechanical load from 70kN, 120kN, 160kN to 210kN and etc. With computer control, entire procedure can be defined, viewed by live curve and results can be saved and printed, which is quite easy to be observed.
