These specifications provides the manufacture and testing, as well as individual design, electrical, mechanical, and workmanship requirements for a system of flexible insulated temporary bypass jumpers used on energized power lines and equipment. These specifications for a system of bypass jumpers are covered in four parts as follows: clamps for bypass jumpers; ferrules for bypass jumpers; cable for bypass jumpers; and bypass jumpers (complete assembly with clamps, ferrules, and cable). The use and maintenance of these equipments are not addressed in these specifications.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
