High-voltage cable shielding layers are designed to protect the cable and surrounding equipment from electromagnetic interference (EMI) and to provide a path for fault currents to ground. They are typically composed of either a braided wire shield, an aluminum foil tape shield, or a combination of both. Additionally, semi-conducting layers are used to even out electric stress within the cable.
Overmolding is a process where a plastic material is injected into a mold containing a pre-assembled connector harness, creating a protective outer layer that encapsulates the wires and connectors. This process, typically using injection molding, provides enhanced protection against environmental factors, improved strain relief, and can integrate complex shapes or textures.

The design of automotive circuit harnesses needs to comprehensively consider safety, reliability, electromagnetic compatibility and maintenance convenience. The following are the core design methods and principles:
The insulation characteristics of a cable harness, like dielectric strength, insulation resistance, and resistance to various environmental factors, are crucial for safe and reliable performance. Proper insulation prevents electrical shorts, signal degradation, and physical damage, ensuring the harness’s longevity and functionality.

An HVAC circuit generally uses NM cable. The higher the amperage of the system, the lower the gauge of wire you’ll need. 例如, a smaller 20-amp unit will require a 12-gauge wire, while a 30-amp unit will require a 10-gauge wire.
Car recalls related to wiring harness issues often stem from damage, improper routing, or defects that can lead to safety hazards like electrical shorts, power loss, or even fires. These issues can affect various systems, including power steering, backup cameras, airbags, and even the engine’s electrical components.
The rise of electric vehicles (電動汽車) is a major force in automotive wiring innovations. EVs and hybrids require complex wiring systems to manage high-voltage electric drivetrains, batteries, and advanced electronics. These systems necessitate specialized harnesses that can handle increased voltage and intricate connections for electric propulsion. OEMs and startups alike must consider the number and sophistication of technology features they integrate into their vehicles as they have a direct effect on harness weight, bundle diameter, and cost.
UL Solutions offers testing services for various types of automotive cables used in the industry over a wide range of extreme temperatures. When it comes to cars, trucks, and other vehicles, wiring plays a huge role in keeping everything running smoothly. Automotive wiring isn’t just about connecting parts; it’s about ensuring safety, durability, and performance. Whether it’s powering your car battery, keeping your music crisp, or lighting up a trailer, the right wires make all the difference.
