Testing method for electrical performance of J1939 splitter Y cable
The J1939 splitter Y cable is an important component used in CAN bus communication to achieve multi device connection. The following are the electrical performance testing methods for the J1939 splitter Y cable:
Electrical performance testing
Insulation resistance test
Use a megohmmeter to measure the insulation resistance between cable cores and between cores and shielding layers, ensuring that the insulation performance meets the standards. Poor insulation may cause signal interference or short circuits.
Conductor resistance test
Measure the direct current resistance of the conductor using the four wire method to verify whether it meets the design specifications. Excessive resistance can affect the quality of signal transmission.
Voltage withstand test
Apply AC or DC voltage higher than the working voltage for 1 minute, check whether the cable has breakdown or flashover, and ensure safety in high voltage environments.
