and low operation efficiency and safety under the "threaded" connection method of the existing insulating operating rods used in distribution network live-line work and daily maintenance
an improved lightweight insulating short-rod combination tool is developed. The insulating rod is fabricated from basalt fiber using an internal foaming molding process
and a quick-connect connection method with superior flexural performance is adopted. By expanding the functions of the insulated rod tool head
the combination tool is made suitable for distribution network live-line work and daily maintenance scenarios. Electrical and mechanical performance tests are conducted on the formed lightweight insulating short-rod combination tool
and static bending load tests
torque tests
and tensile tests are carried out on the insulating rod connector. The results show that the lightweight insulating short-rod combination tool with optimized rod body connection has excellent electrical and mechanical performance
and the connector shows no abnormality under the specified bending load
torque
and axial tensile force
which can significantly improve the on-site working efficiency.
