Equipment Overview

Samples and Restrictions: Information technology equipment, low-voltage switchgear and control equipment parts

Application: Suitable for arcing resistance testing of electrical and electronic products, household appliances and their materials. Simulates possible leakage that may occur on insulators between live parts of different polarities or between live parts and grounded metal parts. Used to measure and evaluate the arcing resistance of insulators under specified voltage conditions.

Test Principle: The high current arc ignition test apparatus adopts double electrodes. Under specific current (33A) and power factor (COSφ0.5) conditions, according to a defined arc ignition speed (254mm/s) and repetition frequency (40 times/min), the arc is repeated 200 times on the sample surface. The high-current arc ignition resistance (HAI) of the sample is evaluated based on whether the sample ignites. Smaller level numbers indicate materials that are harder to ignite.

Structure: The chamber structure includes a protective cover for operator safety.
