Abstract A molded corona shield structure for a high voltage coupling, molded about the outer surface of the coupling and extending beyond the end thereof with an axial passage therethrough to permit entry of a conductor through such corona shield into the inner cavity of such coupling while making a tight fit with the exposed cable insulation. The corona shield is molded from a semi-conductive material composed of elastomeric materials containing a high percentage of highly conductive carbon black. Placed about the outer surface of the corona shield and the coupling is an insulating jacket so arranged as to form an intimate void free interface between the inner surface of the insulating jacket and the outer surface of the corona shield. A semi-conductive layer placed about the outer surface of the insulating jacket may be suitably joined to the semi-conductive outer layer of a cable by means of semi-conductive tape to finish the splice.
A coupling as defined in claim 1 wherein said corona shield is comprised of two similar parts, one each placed about each of the first and second ends of said outer member and said insulating jacket extends about both of said corona shield parts.
Claim 2
Dependent Claim
22 words
A coupling as defined in claim 2, wherein the juncture between said corona shield parts and said insulating jacket is void free.
Claim 3
Dependent Claim
22 words
A coupling as defined in claim 2, wherein said corona shield parts each extend beyond their associated ends of said outer member.
Claim 4
Dependent Claim
19 words
A coupling as defined in claim 2, wherein each of said corona shield portions has an axial passage therethrough.
Claim 5
Dependent Claim
21 words
A coupling as defined in claim 1 wherein the juncture between said corona shield and said insulating jacket is void free.
Claim 6
Dependent Claim
20 words
A coupling as defined in claim 1, wherein said corona shield extends beyond the associated end of said outer member.
Claim 7
Dependent Claim
16 words
A coupling as defined in claim 1, wherein said corona shield has an axial passage therethrough.
