FAQ

What exactly is the task / function of the component?
The cable establishes the defined electrical connection between two points of the system and transmits power or signals with the lowest possible contact and line resistance. The number of cores and the cross-section are functionally relevant.

How do you recognize a defect / typical symptoms?
Defects are indicated by voltage drops, sporadic interruptions, heating under load or malfunctions when the cable is moved. Common causes are wire breakage, crushed insulation, chafing or oxidized crimp contacts.

How do you check / test the component?
Continuity, insulation condition and voltage drop are measured under real load. In addition, crimping points, connector body, strain relief and traces of corrosion on open strands should be checked.

When should it be replaced?
The cable should be replaced in the event of conductor breakage, thermally damaged insulation, corrosion in the conductor bond or contacts that are no longer firmly seated. Preventive replacement is advisable for hard, brittle insulation in heat or salt water zones.

How do you check compatibility?
The OEM number, cable length, number of cores, conductor cross-section, connection types, connector types and, if applicable, the pin assignment are important. In the case of pre-assembled cables, the locking mechanism, seal and installation direction must also match.
