Trolley Insulator, circa 1885
THF177973 / Trolley Insulator, circa 1885
01
Artifact Overview
Most electric streetcars took their power from an overhead wire. A trolley wheel, at the end of a spring-loaded pole, contacted the wire and collected electric current. Insulators made from non-conductive materials -- like glass, porcelain, rubber, or wood -- isolated the electrified contact wire from its supports.
