The electrical insulation performance of high thermal conductivity industrial control aluminum substrate is excellent.1. Insulation layer materialHigh thermal conductivity industrial control aluminum substrate is usually composed of aluminum plate, insulation layer and circuit layer. Among them, the insulation layer is generally a dielectric material, such as ceramic or polymer. These materials have good insulation properties and can effectively isolate the circuit from the aluminum plate to prevent current leakage and short circuit.2. Electrical insulation performance testElectrical insulation performance is usually evaluated through a series of rigorous tests, including but not limited to breakdown voltage test, leakage tracking test and arc resistance test. High thermal conductivity industrial control aluminum substrate can usually show good performance in these tests.Breakdown voltage test: High thermal conductivity industrial control aluminum substrate has a high breakdown voltage, which means that it can still maintain its insulation performance without being destroyed under higher voltage. This helps to ensure the safe and stable operation of electronic equipment under high voltage environment.Leakage tracking test: Leakage tracking test is used to evaluate the traces formed by the material under the combined action of current and voltage. The insulating layer of the high thermal conductivity industrial control aluminum substrate can effectively resist the occurrence of leakage tracking, thereby maintaining its good insulation performance.Arc resistance test: The arc resistance test evaluates the stability and damage resistance of the material by simulating the erosion of the arc. The high thermal conductivity industrial control aluminum substrate can usually show good arc resistance in these tests, which means that it can maintain its structural integrity and insulation performance under high temperature and high pressure environment.3. Reliability in practical applicationsDue to its good electrical insulation performance, the high thermal conductivity industrial control aluminum substrate has been widely used in many electronic devices. These devices include but are not limited to high-power electronic devices, LED lighting equipment, automotive electronics, etc. In these applications, the high thermal conductivity industrial control aluminum substrate can effectively transmit current and signals while maintaining its good insulation performance, thereby ensuring the stability and reliability of electronic equipment.In summary, the high thermal conductivity industrial control aluminum substrate has good electrical insulation performance, which is due to its high-quality insulation layer material and strict electrical insulation performance testing. In practical applications, the high thermal conductivity industrial control aluminum substrate can maintain its good insulation performance, providing a strong guarantee for the stable operation of electronic equipment.
