When the cable television and telecommunications revolution began in the 1980s, Fushi Copperweld’s copper-clad aluminum (CCA) and Copperweld copper-clad steel (CCS) wire quickly became the worldwide standards for coaxial CATV cable. Aluminum is very flexible and light in weight, and when clad in copper, provides excellent conductivity at a significant savings over copper alone. Copperweld combines steel's ruggedness and durability with copper's conductivity for ease of installation.
Copper-clad aluminum wire is the standard material for trunk or distribution cables in the cable television industry. Coming into the home, Copperweld® CCS forms the center conductor of the majority of coaxial cables being used in CATV. In this high-frequency application, the signal travels along the skin of the conductor, so bimetallic wire can be substituted for copper wire on a size-for-size basis. This results in a substantial cost savings because CCA’s lighter weight (37% of that of copper) provides 2.7 times the length of cable per pound than pure copper. Additionally, the lighter weight permits the use of a lower density dielectric, reducing the amount of signal attenuation resulting from the higher density material required by copper wire.
More pliable than copper, CCA is easily formed during installation, minimizing the chance of impedance distortion, caused by dislocation of the center conductor at bends and traps. Cable failure due to conductor pull out or buckling is also greatly reduced.
CATV DROP CABLES
Our genuine Copperweld® copper-clad steel (CCS) is the wiring of choice for CATV drop cables, because of its high strength, fatigue resistance, economic value, good conductivity, and long life. These characteristics allow the cable to safely withstand storm loads and other hazards to which drop wires are subjected.
TELEPHONE DROP WIRE
Copperweld conductors are specified for telephone aerial drop wire by leading telephone systems throughout the world, because of their high strength, good conductivity, mechanical ruggedness, economy, and long life. It is also particularly growing in use as telephone service becomes established in emerging nations. Insulated in pairs, CCS provides durability, conductivity, economy, and long life. It also allows for efficient installation and proven performance in remote locations where reliability is a key consideration. Its resistance to theft is an additional advantage in isolated or unguarded areas.
