→Composite insulator is a kind of special insulation control, which can play an important role in the transmission line.It can also be divided into rod suspension type composite insulator, needle type composite insulator, cross arm composite insulator, support composite insulator, windproof offset composite insulator, etc.
→Mainly used to make tensile tests for composite insulators.
→If there is necessary to make stress corrosion test in nitric acid solution for composite insulator mandrel, an anti-corrosive container will be equipped with the machine. Apply a certain constant load according to the regulations, and keep 96h to check whether it breaks, which will be as one of the criteria for product qualification evaluation.
→Comply with standard GB/T 19519-2014.
→max. Test force: 500kN
→test speed: 0.001300mm/min
→test stroke: 1000mm
→span between columns: 800mm
→main frame: horizontal structure
