History
Vintage Glass insulators were first produced in the 1850s for telegraph lines, then for telephone and power transmission lines. They insulated and protected the wooden poles from the electricity coursing through the wires. They are made from glass, porcelain, or composite polymer materials (non-conductive materials).
