While electric passenger cars have now become an integral part of our daily lives, commercial vehicles are also undergoing a technological revolution. They are setting new standards in terms of efficiency and environmental friendliness, but the technical demands placed on these vehicles are particularly high: extreme weather conditions, constant stress, and the safe handling of high-voltage currents present technical challenges for manufacturers and suppliers. The safe electrification of commercial vehicles requires components made from suitable materials, especially in the high-voltage range. In one of our projects, EPLAMID 6 GX0 30 ORNG Q1D0C201—which was developed specifically for these applications—has proven to be exceptionally well-suited. With its favorable properties, this polyamide is an integral part of our diverse product portfolios for future-oriented applications.
Safe E-Mobility Thanks to Epsan's Innovative High-Performance Plastic, EPLAMID
One innovative example of its application is the high-voltage connector for inverters, which is used in vehicles such as electric buses and electric snow removal vehicles, as well as in electric street sweepers. What may seem unremarkable at first glance is, in fact, the heart of the electric powertrain. It serves as the bridge that channels the immense electrical energy from the inverter to the vehicle’s various systems. But the high-voltage connector must not only transmit electricity—it must also withstand extreme conditions. Resistance to heat, cold, vibrations, and chemicals is one aspect of the requirements. The other is the strict safety regulations for high-voltage components.
But what makes a high-voltage connector not only functional, but also safe, reliable, and durable? The answer lies in innovative high-performance plastics that were developed specifically for these applications.
A plastic designed for electric mobility
In electric mobility, the key to success often lies in the details. And one of these details is the high-voltage connector. To optimize these connections, EPLAMID 6 GX0 30 ORNG Q1D0C201 has proven to be a game-changer—a high-performance polyamide developed specifically for these applications. It combines properties that are precisely tailored to the demanding requirements of high-voltage systems. Epsan’s polyamide meets important criteria such as the UL94-V0 flame classification with a wall thickness of just 0.8 mm and ensures that the connector does not fail even under extreme conditions. The striking orange color (RAL2003) clearly indicates that high voltage is present—a life-saving warning color for technicians and maintenance personnel.
Polyamide offers exceptional flowability and ductility
In addition, the material is characterized by exceptional flowability and ductility, which makes it possible to connect the individual parts of the connector using simple snap hooks—a simple yet ingenious solution for what is otherwise often a complicated assembly process. No screws, no complicated connections.
In addition to its mechanical robustness, the material’s chemical resistance is also a real advantage. EPLAMID 6 GX0 30 ORNG Q1D0C201 withstands aggressive chemicals and environmental influences in accordance with ISO 16750-5, which is particularly crucial for vehicles operated under adverse conditions. Another highlight is the material’s excellent suitability for laser marking. This enables precise, long-lasting marking of components, which is essential—especially in the field of high-voltage systems—to ensure clear and traceable identification at all times.
A Key Role for Innovative Plastics
The Grässlin project “High-Voltage Connectors for Commercial Vehicles” is a striking example of how innovative plastics meet the demands of electric mobility, ensuring not only safety and reliability but also ease of use and a long service life. These technologies bring us one step closer to a future in which electric commercial vehicles will play a key role in creating clean cities and enabling efficient, environmentally friendly industrial processes.
