Wirt Arc Lamp Hanger offered by Electrical Supply Company Chicago

Wirt Arc Lamp Hanger.

The new arc lamp hanger shown in the cut was designed by Chas. Wirt of Chicago. It is so made, it is stated, that it combines simplicity, strength, and very high insulation. A good quality of hard rubber is the insulation used, and the design is such that the full benefit of the high insulating qualities of this material with a large corrugated skirt surface is obtained

At the same time the quantity of material required is small. The metallic inclosing case protects the device from the weather effectually and at the same time supports the hard rubber, so that the strength is ample. It has heretofore been customary to use glass petticoat insulators where extremely high insulation was required in suspending arc lamps on high tension circuits. The design of an unbreakable device, with even higher insulation than can be secured by means of glass, will be generally appreciated. The hanger is introduced by the Electrical Supply company.
