120-Kv Compression-Type Cable

1. Methods normally used for pulling cables into ducts can readily be adapted to the installation of compression cable in steel pipe. 2. Conditions in this country make it possible to eliminate the armor which is used on compression cable abroad. 3. By cabling the individual lead-covered and reinforced conductors with a suitable lay, longitudinal expansion becomes of no practical importance, and expansion bends as used abroad can be eliminated. 4. Diaphragm action of the lead sheath when in nitrogen shows indefinite life under simulated operating conditions. 5. Compression cable is well suited for handling loads in the range of 100,000 kva. 6. The experimental installation which has been installed for approximately one year shows no deterioration of the insulation even on the phase with the lead sheath perforated every 25 feet.
