Period

This example new/never used. This type of insulator used since c. 2009.

Canada

An example of an insulator made in Canada by K-Line, one of very few companies that keeps the production line in Canada and has not out sourced any of its operations. The company was established in 1983 with its head office located in Toronto. K-Line Insulators products are distributed world-wide through a consolidated network of representatives. Even though the quality of the products is superior, the company finds it difficult to compete with manufacturers who moved their facilities outside of the country. The company employs 40 workers per shift and provides in-house training. The operations are a combination of machine and human work. The quality check is done by mechanical means and then verified by a person. The output is approximately 8,000 insulators per day.

Function

Used in electrical power transmission to separate conductors to prevent a flow of current between them or to other objects.

Technical

This insulator illustrates the latest stage in the development of insulators, from glass to porcelain, and finally to synthetic materials. The new material has been introduced to allow for larger voltages to be transmitted over a longer distance. "Synthetic polymers rank among the most important materials to have affected electricity transmission in the latter half of the 20th c., and allowed the exploitation of the hydroelectric potential of the Canadian North. Polymeric insulators, also called non-ceramic insulators or NCIs, were first introduced in 1959, and became available through the 1960s and 1970s." (Megaprojects. H.A. by C. Wittmann and T. Everson. CSTM, 2004.) This type of insulator is used on overhead lines operating at or below 69kV and supports line conductors. K-LINE INSULATORS' highly developed proprietary silicone rubber formulation is characterized by its superior performance under contaminated conditions. The insulator is injection molded in a one piece design and exhibit self-cleaning characteristics. The rubber is highly bonded to the fibreglass core strength member with impervious rod sealing system at the interfaces. These products have a long and proven performance record in severely contaminated environments. Because of its hydrophobicity, this insulator inherently resists water filming and limits leakage of current.
