摘要：
A fire retardant cable for use primarily as a riser cable in buildings has a plurality of groups of twisted pairs of conductors arranged in a "honeycomb" structure. Each conductor comprises a metallic conducting member encased in a single layer of a non-flame retardant polyolefin material such as high density polyethylene. The groups of conductors are surrounded by a jacket of flame retardant poly(vinyl chloride) material.
