Test port – own domestic advanced short-circuit test technique; can provide multi testing ports for different voltage grades, perform short-circuit test items for more than 10 samples simultaneously, and carry out performance test to low-voltage  electric apparatus under full working condition.

Short circuit test---three-phase 1800V、500kA

DC: 440V、320kA  12kV,175kA

Temperature rise test—long term test current 35kA, short time test current 120kA (symmetrical wave)

Electrical endurance test—can carry out durability test of electrical apparatus, of which when A.C contactor is put in the electrical endurance test under the condition of AC-3, AC-4, while the maximum rated voltage reaching 690V, and the maximum rated current can reach 800A

Environmental Test – can perform high and low temperature test, humid heat test, salt spray test, IP test upon electric apparatus, and the volume of dust-proof test box is 420m³， which could conduct IP test in the range of IP00-IP68

Mechanical Test—can perform shock vibration test, impact test, tilt and sway test, pull test, bending test and torsion test

Sliding contact type bus way test—can do performance test for sliding contact type bus way under the dual operating conditions (voltage, current), the regulating ranges of voltage and current are wide, the test precision and efficicency is high

Corrosion resistance test---sulfur dioxide accelerated corrosion test for protective layer of metal materials, components and electron device

UV test---to adopt the xenon arc lamp which can simulate the whole spectrum of sunlight to reproduce the destructive wave in different environments, and can provide corresponding environmental simulation and accelerated test for R&D, and quality control of assemblies

Power harmonic and filtering detection ---- under the condition with harmonic source, to test the suppression harmonic and filtering functions for assemblies with those functions
