Copper Service Entrance (SE) Cable
Copper SE cable – premium choice for safe, high-efficiency service entrances.
Superior conductivity and performance for demanding residential loads.
Built with copper conductors for long-term durability and minimal voltage drop.
Ideal for underground or overhead entry – fire-rated and flexible.
Heavy-duty copper SE cable – trusted in commercial and high-end residential wiring.
Application
Copper Service Entrance (SE) Cable is engineered for reliable power delivery from utility connections to residential, commercial, and light industrial buildings. Featuring high-purity, annealed stranded copper conductors, this cable provides superior electrical conductivity, corrosion resistance, and excellent mechanical flexibility compared to aluminum counterparts.
The cable is insulated with durable PVC or sunlight-resistant thermoplastic jackets, designed to withstand outdoor exposure, moisture, and temperature variations. Copper SE cables are commonly available in two- or three-conductor configurations, including a bare or insulated copper ground wire for enhanced safety and fault protection.
Their robust design makes them suitable for service entrance wiring, panel feeders, and branch circuits requiring high reliability.
Copper SE cables are preferred where maximum conductivity, long-term durability, and minimal voltage drop are critical. Though typically more expensive than aluminum, copper cables deliver better performance in demanding environments and tighter installation spaces.
