Tinned THW-2 ground wire is often used for telecommunication and cell tower grounding but also works for power and lighting across residential, commercial, and industrial applications. Additionally, tinned THW-2 ground wire can be used in conduit and other recognized raceways for service, feeders, and branch circuit wiring.

The conductor is made from 600 V dual-rated tinned copper and has a sunlight resistant green PVC jacket. It can safely operate in temperatures ranging from -25°C to 90°C in wet or dry locations.
