High-voltage applications are classified as such because they meet at least one of two conditions: they are at high risk of experiencing arcing or causing electrical shock through proximity or contact. In these situations, specialized equipment must be used to accommodate the large electrical load distributed and alleviate the danger posed. That’s where high-voltage cable assemblies come in.

What Are High-Voltage Cable Assemblies?
Click to Expand
High-voltage cable assemblies are electrical components that are engineered for use in high-voltage applications. They consist of three main components: cables, high voltage connectors, and accessories. Despite this simple design, they must be carefully constructed. Otherwise, they may not provide adequate performance or protection.
Key Considerations for High-Voltage Cable Assemblies
Given the critical role high-voltage cable assemblies play in electrical and electronic equipment, it is important to choose cables, connectors, and accessories appropriate for the particular application. Below, we highlight some of the key considerations to keep in mind when selecting components for a high-voltage cable assembly.
Cable Considerations
There are many types of cables available, each of which offers distinct advantages that make it suitable for different applications. When choosing a cable for a high-voltage cable assembly, it is vital to consider the cable’s gauge and insulation material. The gauge influences how much operating current it can handle, while the insulation material affects how much operating voltage it can handle. Other elements you may want to add to an assembly depending on the operating and environmental requirements of the application are:
- Additional conductive/insulation layers. Extruded cables are an excellent choice for high-voltage cable assemblies. They can come in single, double, and extruded variations. Single extruded cables feature a single conductor encased in an insulation layer. Double extruded cables feature a single conductor encased in an extruded semi-conductive layer, both of which are encased in an insulation layer. Triple extruded cables feature a single conductor encased in two extruded semi-conductive layers, all of which are encased in an insulation layer.
- Shielding/jacket layers. Shielding and jacketing materials add additional layers of protection to a cable assembly. They defend the assembly from various environmental factors, such as heat, cold, moisture, and stress.
Connector Considerations
Connectors come in a wide range of styles and sizes. It is important to choose the options that are appropriate for the cable assembly application. Typical styles available include bulkhead receptacles, inline plugs, inline receptacles, and right-angle plugs. The connector size should be chosen with regard to operating voltage/current requirements and size restrictions.
Accessory Considerations
High-voltage cable assemblies may feature a variety of accessories that help them work. For example:
- Cable clamps keep the cable in place inside of the connector
- Strain relief adapters minimize mechanical stress
- Straps and other restraints ground and secure the cables
