Strain Insulators 33kv

In the transmission line, at a corner line is a great tensile load. To maintain this huge tension, strain insulators are utilized at sharp corners. In high voltage transmission lines, these insulators include a set of suspension insulators. So, the suspension insulator string can be placed horizontal plane whereas the discs of an insulator are arranged in a vertical plane. To maintain high tensions, more than two suspension strings are connected in parallel. For fewer voltage lines like < 11 kV, then shackle insulators are employed like strain insulators.
