A STRUCTURE OF CONDUCTIVE SLEEVE AND CORONA SHIELD FOR CONNECTING DIFFERENT TYPE POWER CABLES, A PRE-MOLD JOINT BOX HAVING THE SAME, AND METHOD OF CONNECTING DIFFERENT TYPE POWER CABLES

摘要

PURPOSE: A structure of a conductor sleeve and a corona shield, a pre-mold connection box including the same are provided to prevent local overheating of the pre-mold connection box by preventing a space between the corona shield and an insulation unit to be formed. CONSTITUTION: A conductor sleeve(240) comprises first second conductor connection units(242a,242b) which have different inside diameter in order to accept a conductor of different type power cables. The conductor sleeve has a stepped pulley unit(244) in the middle side. A corona shield(250) is offered to the outside of the conductor sleeve. The corona shield has a tapered incline(252). An insulation unit is offered to outside of the corona shield and the different type power cables.
