Typical Specifications
Oil Immersed Terminations - 72.5 to 245kV

General
This specification covers the requirements for a transmission voltage, extruded dielectic cable terminations for oil filled transformer or switchgear applications. The termination design shall be G&W style PATR and suitable for use on single conductor cables through 245 kV. The terminations shall be used on single copper or aluminum conductor cable with extruded insulation from 127-2000 mm2 (250 - 4000 kcmil).

Standards and Ratings

The terminations shall be designed, tested and built in accordance with applicable sections of IEC 840, IEEE 48 for Class 1 terminations, AEIC CS7 and AEIC CS6. The terminations shall be rated:

Rated Voltage, kV (IEC) 72.5 123 145 170 245
Rated Voltage, kV (IEEE) 69 115 138 161 230
Rated Voltage, kV (IEEE) 350 550 650 750 1050
