Where Is Low Voltage Cable Used in EV Infrastructure?
OUR SOLUTION FOLLOW-UP QUESTION
HOW TO USE LOW VOLTAGE CABLE
Low voltage wire and cable is used to distribute secondary power to individual charging units at an EV charging station.
It is typically buried underground in conduit or concrete or directly buried to keep people safe and equipment protected.
When selecting cable, look for XLPE thermoset insulated cables manufactured and sourced in the United States.

SELECTION GUIDE
CABLE IN EV CHARGING STATIONS
Commercial electric vehicle (EV) charging stations are powered by either renewable energy, fossil fuels, or utilities. Medium voltage cables are used to connect these power sources to substations and transformers. Transformers then step this down into low voltage. Low voltage cables are used to connect the transformer to switchgear to the individual charging stations—distributing the power essential to charge an EV.
While there are standards for EV infrastructure electrical design, there isn’t a universal specification outlining which cable is required. This could vary significantly from project-to-project. For example, you could use single conductors, shielded or non-shielded tray cable, or even armored cable.
WHAT TO FOR LOOK WHEN SELECTING CABLE
There are a number of factors to consider before selecting low voltage cable for EV charging stations. First, you need to ensure the conductors are insulated with XLPE (crosslinked polyethylene). Thermoset insulations, like XLPE, are more resistant and have far superior electrical performance characteristics than thermoplastic products (THHN/THWN-2). XLPE insulation has a greater ability to resist leakage current and can handle more spikes and in-rushes over longer periods of time.
XLPE thermoset insulated conductors can be installed underground in conduit or concrete or directly buried. This is critical to keep people safe on the EV charging station site while also protecting the cable from physical and environmental damage.
Properly sourcing wire and cable is also an important consideration. EV wire and cable used in U.S. federally funded projects must be Buy American compliant. The Federal Highway Administration announced that by July 1, 2024, they will not fund projects unless 55% of the total cost of components are made or sourced in the United States.
