Guidelines for choosing the fittings at acquisition isolating suspension

Instructions on completing different types of insulators earrings and ears to create the simplest form of single-circuit insulation hangers in the table. Selection of other types of fittings is made depending on the design of insulation hangers (the number of chains of insulators, the number of wires in a phase such as insulation hangers, etc.).
