| 单词 | aerial cable |
| 释义 | aerial cable An outside plant (OSP) communications cable designed to be suspended from poles or other overhead structures.As they are exposed to the elements, aerial cables must be well protected by cable jackets or sheathes, and from critters by armoring. As their hanging weight can be considerable, they also must incorporate load-bearing strength members. Aerial cables also are often pressurized to protect them from moisture in the event of failures in splice cases or insulation. Alternatively, a water-blocking gel or moisture-activated powdered gel can be used for moisture protection. See also cable, icky-pic, and OSP. |
