Description

The orange high-voltage cables that link the battery, inverter and motors: how they are built and shielded against electromagnetic interference, how they are routed, fastened and connected, the precautions for inspecting and servicing HV circuits, and how to measure current, voltage and insulation resistance with the right meters and insulated gloves.

Safety first: hybrid and electric vehicles carry dangerous high voltage. Practise the procedures only in a training workshop, under a qualified trainer, with insulated gloves and tools, and always follow the manufacturer’s service manual.

Based on the SEG training unit “كبلات الفولطية العالية”. Every page of the unit is shown exactly as printed, with its illustrations; the AI Trainer explains each page with you.

Prerequisites: Electric & Hybrid Vehicle Technology and Vehicle Safety & Protection Systems (recommended).
