France SEFELEC was established in 1965, which is a subsidiary of Cooper Industries, a Fortune 500 company known as a global manufacturer and service provider of power electronics products and tools. The cable tester developed, developed and produced by SEFELEC has passed the ISO 9001 quality certification system, and the product quality is stable and reliable. It is widely used in aviation, aerospace, automobile, train, communication, laboratory, military, connector and medical industries. The equipment characteristic high voltage cable tester series includes SYNOR1200、SYNOR4200 and SYNOR5000 The equipment characteristic high voltage cable tester series includes SYNOR1200、SYNOR4200 and SYNOR5000. Its test range is wide, operation is simple and convenient, and it is stable and reliable Testable type: Low - voltage conduction test, short-circuit open-circuit test, four-wire test, 2 - wire / 4 - wire conduction test mode and micro-break test can be used to detect poor cable contact ( intermittent break within 1μ s can be detected ). AC / DC high voltage insulation and withstand voltage test, resistance, capacitance and diode components test in the loop, etc. The number of test points can reach more than 100,000. Windows - based operation test software, test program can generate test program through product self – learning. In order to facilitate the customer manufacturer to develop a set of automatic test program generation software, the contact relationship in the source file can be automatically converted into a test program.
