EEI-Manufacturers 500/550 KV CableE Research Project. Cable D-High Pressure Oil Paper Pipe Type

Abstract: This paper covers General Cable Corporation's development and testing of a 500 KV high pressure pipe type oil filled cable. It also covers the installation of a sample length of this cable at the Edison Electric Institute test site at Waltz Mill, Pennsylvania.

High voltage power cable - constructed to avoid the formation of electrochemical trees in the insulation

Abstract: Power cable has a stranded conductor (12) impregnated with a semi-conductive strand sealant (18), a semi-conductive stress control layer (16) about the conductor, the sealant preventing ingress of moisture between the strand and stress control layer, an extruded polyethylene insulation layer (20) tightly about the stress control layer. A semiconductive insulation shield (24) is provided so tightly about the insulation layer as to prevent ingress of moisture, a metallic shield (30) about the insulation shield with semiconductive sealant compound (26) therebetween to prevent moisture reaching the insulation shield. The sealant is a material which is physically and chemically compatible with the stress control layer and insulation shield and is a compound which maintains its physical and electrical characteristics in spite of temperature changes due to the load cycling of the cable.

Identification and Control of Electrical Noise in Routine-Reel Corona Detection of Power Cables

Abstract: The analytical study of the power separator-filter type of discharge detector, when used to measure corona on long lengths of cable and the use of this type detector in cable factories over a period of years, together with a suggested procedure to determine the partial discharge-voltage stress (corona factor) characteristic has been presented. The detector itself, when used in a cable factory, is only part of a circuit arrangement which necessitates the interconnecting of the high-voltage supply, the detector, and the reel of the cable under test in environments sometimes with large amounts of electrical noise. The sources of electrical noise and their relationships to the parameters of the detector itself are discussed, noise suppression procedures which optimize the circuit arrangements are outlined, and sensitivities in the range of several picocoulombs are obtained in cable factory environment using normal test personnel.

Optical scanning of electrical cable shields

Abstract: This apparatus, for detecting abnormalities in an electrical cable, has probes located at angularly spaced locations around the circumference of the cable. The probes are means for directing light beams against the surface of the cable and are light sensitive elements that pick up the light reflected from the cable surface. As the cable advances with continuous motion through a testing station, changes in the amount of light reflected operate detectors. Adjacent probes are connected with bridge circuits to make the operation independent of changes in the ambient light conditions. This feature utilizes axial as well as angular spacing of adjacent probes. A hinge sleeve for holding the probes facilitates application and removal of the test apparatus to and from the cable; and the sleeve opens automatically to pass protruberances of the cable which would strike the probes.
