What are the years glass insulators were commonly used?

Introduction

Glass insulators have played a pivotal role in the development of electrical infrastructure. Their use spans a significant historical period, particularly in the electrification of telecommunications and power transmission systems.

Historical Usage of Glass Insulators

Glass insulators were predominantly used from the mid-19th century to the early 20th century. Their primary role was to support and separate electrical wires, ensuring that the electrical current was efficiently transmitted without leakage to the supporting structures.

Timeline of Glass Insulators

The primary period of glass insulator use extends from approximately 1840 to 1960, with specific time periods marking significant changes in their application:

• 1840 - 1890: Early development and widespread use alongside telegraph systems.
• 1890 - 1910: Growth in use driven by telephone line expansion.
• 1910 - 1940: Continued use with electrical power distribution, especially in rural areas.
• 1940 - 1960: Gradual replacement by ceramic and plastic insulators as manufacturing technologies advanced.
