Signal Wire
At higher frequencies, current flows along the outer surface of a conductor. That means that the core of a copper conductor is under-utilized. Bimetallic conductors with cores made of select metals can be used to enhance performance.
Copperweld CCS coaxial core conductors provide added strength when cable installations require a more rugged, durable product. Our steel-core conductors offer tensile strength 40% greater than copper coaxial cores. We offer CCS coaxial cores in three conductivities: 21%, 30% and 40%.
Our CCA coaxial cores have lower resistance for improved signal loss and lower voltage drop. That reduces the need to amplify the signal over longer cable runs—especially important in satellite dish and cellular applications. Copperweld offers CCA options with 10% and 15% copper by volume.
Copperweld offers a multitude of coaxial core options. Below is a list of our most popular wires. Contact our sales team to discuss your project needs and start a quote.

Direct-buried and outdoor deployments endure extreme environmental stresses. Copperweld® products provides greater strength, resiliency and flexibility.
Copperweld® brand wire is the most durable ground wire on the planet — capable of remaining ASTM spec-compliant after 80+ years of service.
Is copper theft an issue in your area? Copperweld’s metallurgically bonded conductors have extremely low street value, making it unattractive to copper thieves.
Better energy efficiency than standard copper signal wire conductors.
CCA is lighter than copper and offers standard termination compatibility.
CCA has 50 years of safe residential, commercial and industrial use.
