High-Voltage Cables for Vehicles With Electric/Hybrid Engines

As a technology and innovation leader for automotive manufacturers and system suppliers, HEW-KABEL is a specialist in the development and manufacture of high-voltage (HV) cables for electromobility. These cables are extremely flexible, exceptionally temperature-resistant, and mechanically highly resilient. The wide range of possible cross-sections makes it possible to implement a wide variety of applications.



High Voltage Cables for EVs

High-voltage cables from HEW are used wherever vehicles are powered electrically, e.g.

Hybrid and electric vehicles

  • Fuel cell vehicles

HEW HV Cables - Durable And Innovative

Our HV cables are available with a specially developed additional protective braid. This protects the cable against thermal, mechanical, electrical, and chemical influences. Therefore, the service life and functionality can be significantly extended once again.


At HEW, we also have special cable designs with optimized insulating materials. These allow for increased current carrying capacity. For the electrical design (compared to conventional cables), this feature also allows the selection of a lower cross-section.


1. Engine wiring

High-voltage cables from HEW guarantee the optimum and safe distribution of high voltage to all relevant components and electrical consumers in electric vehicles. Both single-core and multi-core cables are used here.

2. Internal wiring of high-voltage components

High-voltage cables from HEW guarantee the optimum and safe distribution of high voltage to all relevant components and electrical consumers in e-vehicles.

3. Charging cables

HV cables from HEW-KABEL can be found in many areas in e-mobility. An essential area are charging cables for high voltage batteries.
