FAQ
1. What type of wires can be tested?
The machine supports automobile and locomotive wires, including single-core and multi-core cables, with PVC or heat-resistant insulation.
2. How long can the test run continuously?
The machine is designed for long-term testing over 14 days, simulating prolonged exposure to heat and salt water.
3. How is temperature controlled?
Temperature is monitored using a PT100 anticorrosive thermocouple and controlled by an intelligent PID system, maintaining accuracy within ±0.2℃.
4. How is the water level maintained?
An automatic water pump and ball valve system maintain a stable test water level, ensuring consistent testing conditions.
5. Can DC voltage be applied during testing?
Yes, the machine supports an optional 48V DC power supply. For high-voltage testing, the optional JN-DC-50305 tester allows DC voltage up to 5 kV to be applied and recorded.
6. Is the equipment safe from corrosion?
All components in contact with water are made of anticorrosive materials, including the pottery tank, PVC safety fence, and mixing rod.
