TRANSMISSION LINE DUCTS |
摘要 |
A duct assembly comprises a plurality of ducts longitudinally joined together by an interconnecting web. The ducts are preferably arranged in a ribbon format of a single duct in thickness, enabling greater flexibility in that direction than a bundle of ducts. In a preferred embodiment the ducts have a fire retardant outer covering. The duct assembly is also preferably fabricated in a single process. |
