Study on the damage analysis of 110kV cable structure

The market application value of power cables has gradually emerged with the development various industries. Cable laying is a basic project in construction grid and key part engineering construction, content which related to safe reliable operation entire grid. With process cable, metal sheath subjected structural damage such as extrusion deformation. This paper takes 110kV cable line an example, case was introduced detail, targeted measures were proposed based on defects caused by damage. At same time, analysis carried out, simulation are performed, partial discharge test performed damaged portion insulation obtain stress received when recessed, signal detected insulating shielding layer collected. Provide reference for staff cables.
