Self-Supporting Communication Cables Using Copperweld Conductors

摘要

To state the case for self-supporting communication cables, with strength derived from the conductors themselves: there is no doubt that single pair cables, such as telephone drop wire or the well known field wire, have been most successful. Conversely, there would seem to be no doubt that for 100-pair cables, for example, soft copper wires with messenger installation are more economical. In between the 1-pair and 100-pair cables, there is undoubtedly a field for cables with high strength conductors. The range probably includes 6-, 11-, 16-, and 26-pair cables. The designing of suitable attachment fittings has been a most important contribution. The adaptability of Copperweld to copper cable practices has been demonstrated by two manufacturers: rubber-neoprene 6-pair drop wire, 6-pair PVC insulated and jacketed drop wire, and 6-, 11-, 16-, and 26-pair self-supporting cables with polyethylene insulated conductors and PVC jackets.
