Fla 15/60 switching takes place in a tightly closed extinguishing chamber, filled with Shell transformer oil. No leakages of products of combustion are released into the environment. With regard to this fact, Fla 15/60 load disconnectors meet the extreme environmental requirements.Load disconnectors satisfy standards EN 62271-1, EN 62271-102, EN 62271-103. Used insulators satisfy the fourth grade of contamination area.Simple load disconnectors of a sturdy structure proved themselves in an excellent way under very different climatic conditions.The basic welded frame is made of open steel profiles that guarantee perfect surface protection from corrosion caused by heat zinc coating that can be controlled on all places. Heat zinc coating protects the shafts of the load disconnectors mounted in bronze bearings as well as all other steel components.All current conduction components are made of silver plated electrolytical copper and constitute a loopless current conduction path.The load disconnectors are delivered with insulators made of a cyclo-aliphatic resin, silicone or porcelain.
