Cable termination (new industry term for pothead) line expanded to include distribution preassembled Slip-on designs and transmission voltage ATA designs to 500kV. Cable joints extended to 138kV for low pressure, oil filled cable. Oil switch improvements included a light duty (LDR)style to 20kA momentary and heavy duty (RA40) style to 64kA momentary. SF6 gas was introduced as an alternate switching dielectric to oil. A high voltage test laboratory was added.
