High-voltage transmission lines

ARNO carries out construction and repair work on 69 kV to 735 kV power transmission networks, wooden poles, steel pylons, or tubular poles.

Whether for civil projects, structural assembly, or the unwinding of conductors, we have the required expertise and all types of specialized equipment.

Supported by an experienced technical team, and surrounded by reliable partners, ARNO has over the years developed expertise that allows it to perform complex tasks with a constant concern for safety.

Our experience in remote locations has also allowed us to carry out work in the northern areas, in collaboration with Aboriginal communities. We have all the necessary equipment to carry out any type of work (pullers, tensioners, pulleys, etc., for work up to 735 kV).

ARNO is certainly one of the leaders in this sector in Eastern Canada.
