But what exactly are high-voltage cables? The term high-voltage system refers to a system that is operated with AC voltages above 30 V to 1 kV or with DC voltages above 60 V to 1.5 kV.
A ‘high-voltage battery’ (400 V to 800 V) or ‘high-voltage storage battery’ is an electrical energy source for mobile and stationary applications. When used in vehicles, it is also referred to as a traction battery.
High-voltage cables consist of different layers that are crucial to their function. The outer layer is an insulating layer that protects the cable from moisture, dust and other environmental influences.
Underneath is a shield that reduces electromagnetic interference and stabilises the current flow. In the middle of the cable is the actual conductor, which is made of copper or aluminium and transports the current. Depending on the requirements, several conductors can be installed in one cable.
The main difference between a high-voltage cable and a low-voltage cable is the voltage that is transported. High-voltage cables transport voltages in the range of several hundred to 1,000 volts, while low-voltage cables only transport voltages of up to 50 volts. As a result, there are specified safety regulations for high-voltage cables which must be observed.
High-voltage cables are primarily used in electric cars and hybrid vehicles. There they transport the current between the electrical components. In addition to their function in electric and hybrid vehicles, high-voltage cables are also used in other applications, such as in energy technology and industry. Here, for example, they are used to transport direct current or alternating current. High-voltage cables are also used in fuel cells, high-voltage batteries and electrified vehicle electrical systems, where they ensure efficient energy transmission.
HV cables are used wherever vehicles need to be electrically powered, for example:
- Hybrid and electric vehicles
- Agricultural vehicles
- Fuel cell vehicles
- Electric scooters and electric motorcycles
- Industrial trucks
- Other commercial vehicles
High-voltage cables must fulfil various requirements in order to be suitable for use in electric cars and hybrid vehicles. These include:
- High dielectric strength: High-voltage cables must be able to withstand voltages of several hundred volts without failing or breaking through.
- Low losses: High-voltage cables must transmit the current with as little loss as possible to ensure energy efficiency.
- Good insulation: The insulation layer of the high-voltage cable must insulate the current and at the same time protect against environmental influences.
- Robust construction: High-voltage cables must be shock and vibration resistant and must not chafe or wear through.
- Temperature resistance: High-voltage cables must remain stable and functional even at high and low temperatures.

High-voltage cable assemblies: the voltage increases
Function of high-voltage cables
High-voltage cables are used to transmit the high electrical voltages required in electric vehicles and hybrid vehicles to supply the electric drive components. They transport the current from the battery to the motor, generator and other electrical consumers in the vehicle. Despite their high performance, high-voltage cables are particularly space and weight-saving thanks to their innovative design, which gives electric vehicles a greater range and supports CO2 regulation.
It should be noted that high-voltage connectors are used in this area. As connectors establish the electrical connection between electronic high-voltage components, maximum safety is required.
