Great Progress Of TGE's D78H22.5 MOV With 2200A 2ms Withstand Test And 120kA 4/10µs High Current Test

In Nov.07.2017 TGE got the new test report of D78H22.5 metal oxide varistors from XIHARI.

Test classification:Performance Test

Tests have been performaned:

                   Lighting current impluse residual voltage test

                   High current impulse withstand test(120kA, 2 times)

                   Long duration current impulse withstand test(2ms, 2200A, 18 times)

                  Accelerated ageing test

Tests have been performed in accordance with:

                   GB-11032-2010          Metal oxide surge arresters without gaps for a.c. system

                    IEC60099-4-2009      Metal oxide surge arresters without gaps for a.c. system

Conclusion:

                    All the tests above are satisfied the requirements of standards and technical specifications
