This relay consists of a strongly built solenoid mech-anism which operates a timing and circuit-closing ele-ment through a micarta chain of such length as to pro-vide ample insulation for the voltage in use. There isno lost motion in the chain as it is constantly in ten-sion, the action of the solenoid raising a weight on thecontact mechanism. For voltages up to 44,000 the chainconsists of twelve links. Twenty links are provided forvoltages up to 66,000, and thirty links up to 110,000volts. The links may be removed to shorten thechain down to a minimum of one link for each 6600volts. The relay co;l is inserted in the high-voltage line,but the contacts and timing parts are thorou
