Bare

Our original uncoated CCS finish

Bare Copperweld® Copper-Clad Steel (CCS) combines the mechanical strength of steel with the conductivity and corrosion resistance of copper. Continuous copper cladding is metallurgically bonded to a steel core, creating a grounding conductor built for long service life in demanding environments.

Features and Benefits:

  • Connector-ready — no stripping, sanding, or surface preparation required
  • Installed and terminated like standard copper conductors

Camo™

Camoflauge your conductor into the surrounding environment

Copperweld® Camo™ is a 100% copper finish applied using a proprietary process that alters the surface appearance of the conductor. The result is a grounding conductor that performs like copper while visually blending into steel and galvanized environments, helping reduce theft incentives.

Features and Benefits:

  • Connector-ready — no stripping, sanding, or surface preparation required
  • Installed and terminated like standard copper conductors

Hide™

Hide your grounding conductor in plain sight

Copperweld® Hide™ is a PVC-jacketed Copper-Clad Steel grounding conductor designed to visually blend into its surroundings while providing clear, sequential footage markings for installation and maintenance visibility.

Smarter way to protect pole-top connections

Flexible, Durable High-Voltage Stinger Wire for Pole-Top Transformers

Copperweld® Stingray™ is an easy-to-install, covered Copper-Clad Steel (CCS) transformer riser wire designed for pole-top distribution applications. Engineered for animal protection — including bird wire and squirrel wire use — Stingray™ helps reduce outages caused by incidental wildlife contact between primary phase conductors and equipment bushings. With a durable jacket and a strong CCS core built to withstand wind fatigue and weather exposure, Stingray™ supports long-term reliability in critical overhead connections.

Features and Benefits:

Protective Covering – Helps prevent incidental and wildlife contact that can lead to equipment failure, service disruption, and outages in pole-top installations.
Longer Service Life – With a strong CCS core, Stingray withstands wind fatigue up to 8x longer than solid copper, delivering durable performance in harsh overhead environments.
Easier to Install – Stingray’s thermoplastic rubber covering is easier to strip than traditional HMW polyethylene, supporting faster field connections.
Superior Strength – With the strength of steel, CCS resists stretching, breakage, and deformation under mechanical and thermal stress.
