Ready for the Future of Mobility? Our High-Voltage Cables Make It Possible!
So, what exactly are high-voltage cables? A high-voltage system refers to one that operates with AC voltages above 30 V up to 1 kV or DC voltages above 60 V up to 1.5 kV.
A ‘high-voltage battery’ (400 V to 800 V) also known as a “high-voltage storage battery,” is an electrical energy source used in both mobile and stationary applications.
High-voltage cables are made up of multiple layers, each essential to their functionality. The outermost layer is an insulating sheath that protects the cable from moisture, dust, and other environmental factors.
Beneath it lies a shielding layer that reduces electromagnetic interference and helps stabilize current flow. At the core is the actual conductor, typically made of copper or aluminum, which transmits the electrical current. Depending on the application, multiple conductors may be integrated into a single cable.
Der wesentliche Unterschied zwischen einem Hochvoltkabel und einem Niedervoltkabel ist der Anwendungsbereich (Fahrzeugtechnik) sowie die Spannung, welche anliegt. Hochvoltkabel sind für den Spannungsbereich ab 60 V DC bis maximal 1,25 kV DC entwickelt worden, während Niedervoltkabel nur Spannungen im Bereich von ≤ 50 V AC und ≤ 120 V DC bereitstellen. Dadurch gibt es bei Hochvoltkabeln spezifizierte Sicherheitsvorschriften welche eingehalten werden müssen.
High-voltage cables are primarily used in electric and hybrid vehicles. There, they transmit electrical current between components. Beyond their use in electric and hybrid vehicles, high-voltage cables are also employed in energy systems and industrial applications. For example, they are used to transmit both direct and alternating current. They are also integral to fuel cells, high-voltage batteries, and electrified vehicle systems, ensuring efficient energy transmission.
HV cables are used wherever vehicles require electrical propulsion, including:
- Hybrid and electric vehicles
- Agricultural vehicles
- Fuel cell vehicles
- Electric scooters and electric motorcycles
- Industrial trucks
- Other commercial vehicles
High-voltage cables must meet several key requirements to be suitable for use in electric and hybrid vehicles. These include:
- High dielectric strength: High-voltage cables must withstand several hundred volts without breakdown or failure.
- Low transmission losses: High-voltage cables must transmit current efficiently with minimal energy loss.
- Effective insulation:The insulation layer must safely contain current while protecting against environmental influences.
- Robust construction:High-voltage cables must resist shock, vibration, abrasion, and mechanical wear.
- Temperature resistance: High-voltage cables must remain functional under extreme high and low temperatures.

High-Voltage Cable Assemblies: Powering the Future
Function of High-Voltage Cables
High-voltage cables are used to transmit the electrical energy required in electric and hybrid vehicles power the electric drivetrain components. They carry current from the battery to the motor, generator, and other electrical components in the vehicle. Despite their high performance, high-voltage cables are designed to save both space and weight, thereby increasing the vehicle's range and supporting CO₂ emission regulations.
It is important to note that high-voltage connectors are used in this area. Since connectors establish the electrical connection between electronic high-voltage components, maximum safety is essential.
