2 Claims. (01. 11345:)
- a flange 5 and bolted to this flange is a ring 6 which is screwed to the exterior of the lower end of a sleeve 7 surrounding the insulated conductor and constituting a continuation of the cable pipe 1. 1.
Intermediate its ends the sleeve 7- is threaded to receive a flange 8 to which is bolted a, metal cone 9 constituting the bottom of the terminal this cone 9 supporting the porcelain insulator 10 of the terminal which is sealed and bolted at its lower end as shown at 11 to the upper end of the cone.
The upper end of the sleeve 7 is threaded internally to receive and support a pressure tube 12 which in efiect constitutes a continuation of r the sleeve 7 and receives the insulated conductor of the cable; The pressure tube 12 isslightly larger in internal diameter than the outside diameter of the insulated conductor of the cable so as to provide a space between the pressure tube and the insulation of the cable for oil or other insulating fluid under pressure with which the pipe 1 or the cable is-filled. The upper end' of the pressure tube 12 is sealed, being provided with a ring 13 screwed upon the upper end of the tube and a cap plate 14 bolted to this ring.
To the upper end of the conductor 15 of the cable is secured a connector 16 provided with a stem 17 which passes upwardly through the cap plate 14 and is screw-threadednut 18 drawing the connector to'the cap plate. The upper end of the porcelain 10 is sealed by a plate 19 and the stem 1 of the connector 16 passes through this plate where it is provided with a nut 20.
About the pressure tube 12 is a built up tape structure 01' paper or 'varnished cambric designated 21 and about the lower end of this tape structure is shielding tape 22 contacting at its lower end with the upper end of the sleeve 7,
About the upper end oi the varnished cambric or paper tape structure 21 and surrounding the pressure tube 12 are barrier tubes 23.
As above mentioned the pressure tube 12 is interior of the pressure tube.
maintained under internal pressure due to the pressure in the cable pipe 1, the exterior oi the pressure tube, however, is'under static pressure, the insulator 10, which is sealed at both ends be-,- ing kept filled with fluid insulating material such as oil, designated 24 under static pressure.
What we claim is: I I
1. A terminal for electric cables of the pressure type, comprising in combination a ring or gland screwed to the cable pipe, asleeve for receiving the insulated cable conductor and constituting a'continuation of thevcable pipe, a ring screwed to the lower end of said sleeve and bolted liquidtight .to said first mentioned ring or gland, a ring carried by said sleeve intermediate its ends, a 7 cone bolted to said ring, a tubular insulator supported by said cone and sealed thereto at its lower end, means for sealing the upper end of said insulator, a pressureltube within said insulator for receiving the insulated cable conductor screwed .into the upper end of said sleeve and communicating therewith, a built up insulating structure about said pressure tuba-and a metal shield about the lower end of said insulating structure and contacting with the upper end of said sleeve.
2. A terminal for electric cables of the pressure type, comprising in combination a packing gland secured to the end ofthe cable pipe, a vertically extending sleeve in line, with said pipe, a ring secured to the lower end thereof and bolted to said gland to provide a liquid-tight joint between the cable pipe and said sleeve, a ring screwed upon saidsleeve intermediate its ends, a metal cone bolted to said last mentioned ring, a hollow insulator sealed to said cone, means for sealing the upper end of said insulator, a pressure tube for receiving the insulated cable conductor screwed into the upper end of said sleeve, means for sealing the upper end of the pressure tube, a connector secured to the upper end of the cable conductor and passing through the upper end of the pressure tube to the upper end 01 the said insulator, means for securing the same to the upper end 01' the insulator, a built up insu- 1 lati ng structure surrounding said pressure tube intermediate its ends, metal shielding about the lower part of said insulation and contacting with said sleeve, barrier tubes about the upper end of said insulation, and fluid insulation under staticpressure filling said insulator, said fluid insulation being out of communication with the FRED C. MEYER. GEORGE E. MOFFI'I'I.
