What Is Quadruplex Wire and What Is It Used for?

Ewcswire06 Jan, 2026Business

Quadruplex wire is a type of specialty electrical cable that is most commonly used for power service entry to buildings. It can be suspended aerially but sometimes it is run through ducts to a building. It is often used as a service drop from a transformer, as the cable that services the building, but it can also be used underground for secondary distribution, assuming it is rated appropriately for that application.
