Appendix A, Appendix B, and Appendix C of "Insulation Coordination of Equipment in Low Voltage Systems (Part 3): Anti fouling Protection by Coating, Tank Sealing, and Molding (GB/T 16935.3-2005/IEC 60664-3:2003)" are normative appendices. The insulation coordination of equipment in low-voltage systems (Part 3): Anti fouling protection using coatings, tank seals, and molding (GB/T 16935.3-2005/IEC 60664-3:2003) was proposed by the China Electrical Industry Association. The insulation coordination of equipment in low-voltage systems (Part 3): Anti fouling protection using coatings, tank seals, and molding (GB/T 16935.3-2005/IEC 60664-3:2003) is under the jurisdiction of the National Technical Committee for Standardization of Low Voltage Electrical Appliances. Insulation Coordination of Equipment in Low Voltage Systems (Part 3): Anti fouling Protection by Coating, Tank Sealing, and Molding (GB/T 16935.3-2005/IEC 60664-3:2003) was issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Administration of China on August 3, 2005, and has been implemented since April 1, 2006. Content Introduction: "Insulation Coordination of Equipment in Low Voltage Systems (Part 3): Anti fouling Protection by Coating, Tank Sealing, and Molding (GB/T 16935.3-2005/IEC 60664-3:2003)" published by China Standards Publishing House The function of insulation is to separate conductors with different potentials. Insulation coordination refers to determining the necessary withstand strength of equipment based on the various voltages that may occur in the system where the equipment is located, PCF8583, and considering the characteristics of the protective device and the insulation performance of the equipment, in order to reduce the probability of insulation damage and impact on continuous operation caused by various voltages acting on the equipment to a level that can be economically and operationally tolerated; That is to correctly handle the coordination relationship between various voltages, voltage limiting measures, and equipment insulation tolerance in terms of technology, as well as coordinate investment costs economically
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
