What can I do with old porcelain insulators?
Scrap porcelain insulators can be ground up for use in road aggregate, ice melt and outdoor tiling. Sometimes, used porcelain insulators can be re-utilized by the manufacturer as raw material for manufacturing new insulators.
How old are ceramic insulators?
The wide use of ceramic insulators began in the 1950s. They were cheaper to make and more resilient and long-lasting regardless of the climatic conditions. The manufacture of glass insulators stopped in the 1960s and was replaced entirely by ceramic insulators by the 1970s.
What is the most rare glass insulator?

Why are porcelain insulators Brown?
Limonite, grinding waste, flotation waste and iron oxide scale were used as an iron source whereas manganese oxide and ferromanganese were used as a manganese source. The colour of glazed insulator bodies change from dark brown to light brown depending on the pigment composition.
What are old blue insulators worth?
On average, these glass insulators tend to sell for around $20, though there are special instances where insulators can sell for significantly more than that. Generally, the insulators that sell for more are rare, either because of their manufacturer or their color.
What are Hemingray insulators?
Hemingray was the world largest manufacture of glass insulators. The earliest Hemingray insulators are likely lightning rod insulators from the late 1850’s. The last Hemingray insulator was made in 1967.
Are old insulators valuable?
Why are insulators used with overhead line?
The insulators in overhead transmission lines are required to withstand both mechanical and electrical stresses. The mechanical stress is due to the conductor load, wind load, etc. while the electrical stress is mainly due to line voltage and it may cause the breakdown of the insulator.
Does Hubbell make Ohio Brass?
The acquisition of Ohio Brass® in 1978 was Hubbell® Incorporated’s first foray into the power systems sector. Today, Hubbell Power Systems, Inc. (HPS) manufactures Ohio Brass polymer and porcelain insulators and arresters used in the transmission, substation and distribution markets.
Where are Ohio Brass Products made?
Ohio Brass was founded in 1888 in Mansfield, Ohio. Today, HPS continues to manufacture these legacy products in Wadsworth, Ohio along with our Aiken, South Carolina location.
What types of posts does Ohio Brass offer?
Our designs include suspension, station and line post, as well as polymer insulator and arrester combinations for lightning protection. Ohio Brass was founded in 1888 in Mansfield, Ohio.
