New Lexington high-tension porcelain insulator

High-Tension Porcelain Insulator.

The accompanying illustration shows a 60,000-volt porcelain insulator made by the New Lexington High Voltage Porcelain company, of New Lexington, Ohio. The insulator is 14 in. in diameter and 12-1/2 in. high, and its net weight is 25 lb. The Seattle-Tacoma Power Company has ordered insulators of this type for use on its three-phase transmission line from Snoqualmie Falls to Everett, Wash., which line was built in 1906 and placed in operation in December of last year. The original voltage of transmission was 15,000, but it is now proposed to raise this to 30,000 to conform with other lines operated by the company. Considerable new business is expected within the next four or five years, and the 60,000-volt insulators are now being installed in anticipation of increasing the voltage from 30,000 to 60,000 volts. The New Lexington High-Voltage Porcelain Company considers the insulator shown to be particularly adapted for this class of work.
