Title:
HETEROGENEOUS POWER CABLE CORE CONNECTION DEVICE AND HETEROGENEOUS POWER CABLE CONNECTION SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/149803
Kind Code:
A1
Abstract:
The present invention relates to a heterogeneous power cable core connection device and a heterogeneous power cable connection system including same, in which the volume of the connection device for connecting heterogeneous power cable cores is minimized, and during application of a current to conductors of the heterogeneous power cable cores, the occurrence of cracks in an insulation molding portion having a connection conductor embedded therein can be minimized. The heterogeneous power cable core connection device comprises an insulation connection sleeve including: a connection conductor having one end, to which a conductor of a paper-insulated power cable core is connected, and the other end, to which a conductor of an XLPE power cable core is connected; and an insulation molding portion surrounding the outer circumference of the connection conductor, wherein the connection conductor comprises a constant diameter portion, an expanding diameter portion of which the outer diameter expands from the constant diameter portion, and a depression portion into which the conductor of the XLPE power cable core is inserted, and a longitudinal inclination at an arbitrary point of the outer circumferential surface of the insulation molding portion surrounding the expanding diameter portion has a level between the minimum inclination and the maximum inclination of the outer circumferential surface of the expanding diameter portion.
