DX842B Wire and cable high voltage leakage marking tester
Overview:Used to test the ability of wires and cables to withstand electrical trace formation. Simulate the actual environment and spray a 0.1% sodium chloride solution at a certain speed and flow rate on a vertically placed sample. At the same time, apply a high voltage. If the sample current does not exceed 1A during this cycle, the sample will not burn, there will be no continuous arc between the electrode and the ground, and there will be no breakdown phenomenon in the sample, then the sample is considered qualified.Suitable for single core cables and can also be used for multi-core cable detection.
Scope of application: it is used for the ability of wires and cables to withstand damage caused by electric traces caused by surface leakage under dirty conditions.
Compliance with standards: comply with the requirements of GB/T 3048.1-2007 test methods for electrical properties of wires and cables and GB/T 3048.7-2007 test methods for electrical properties of wires and cables: Part 7: Test standard requirements for resistance to electric traces.
Technical parameter
Test voltage: 0~6000v adjustable
Test current: max. 2A
Alarm current: 1 A
Voltage regulator: 10KVA Output 0~250v
High voltage transformer: 10KVA Output 0~5000v
Electrode clamp: made of all copper

Equipment composition and characteristics: electric control part, spray device, high voltage generator, voltage regulator and sewage liquid collection device; The exterior of the equipment is made of all stainless steel, and the interior is sealed with corrosion-resistant and insulating epoxy plates, effectively preventing electric leakage and polluting liquid from corroding the metal shell.
It is one of the main products of our company. It is jointly developed by our company and Guangzhou CVC cable testing center. It uses PC+PLC intelligent control technology to automatically measure and control the spray cycle and maximum spray times. The test data can be stored and printed; The spray control part is made of stainless steel box, and the spray pool is made of transparent acrylic plate like crystal, which is beautiful and elegant. The instrument is humanized in design, simple in operation, easy to use, and safe to show the traces of high-voltage leakage with a factory sales voltage of 5000V.
