TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic insulation determination, especially to a plastic insulation determination device. BACKGROUND

[0002] Plastic insulation determination is a series of tests used to evaluate the electrical insulation performance of plastic materials, which is crucial for ensuring the safe operation of power, electronic and related products. These tests include insulation resistance testing, which measures the material's ability to resist current flow; dielectric strength testing, which assesses the material's maximum voltage bearing capacity under high electric field; weather resistance and heat resistance testing, which simulates performance changes under natural light, high and low temperature environments and humid conditions; and chemical corrosion resistance testing, which evaluates the material's durability in different chemical media.
