A line course in Engerdalssetra

This course is a well preserved national- and subscription line course on one and the same pole. It’s likely that the course initially was a pure national course. Because of short poles, it was problematic to make space for expansions when the need for subscription lines increased. The problem was solved by using 8-way pole arms, in the Norwegian technical terminology called telefonjern nr.4. With this type of pole arm, better use was made of the pole length, and fewer poles had to be replaced.

Apart from this, it was common to adapt the width of the line course to the surroundings. Around house corners, passing fruit trees and through woodlands, it was often more suitable with a narrower line course. The type of pole spar or pole arm and their width can therefore vary throughout a subscription course.

The protected stretch consist of approximately 100 poles with rare 6- and 8-way pole spars (pole arms)

Parts of this line course carry cable that is still in use.
