Common Causes Of Cable Termination Heating

1、High Voltage Cable Termination Structure and Insulation Mdium

1.1 Overall Structure

High-voltage cable terminations can be divided into porcelain sleeve type, composite sleeve type, integral prefabricated type, GIS termination, etc. Their core structure is similar. The description here is based on the ceramic sleeve type cable termination structure as an example.
