Type EST is ideally suited for both indoor and outdoor applications. It is available for voltages from 72.5 kV up to 170 kV. It consists of one flexible ESF type termination and either one or three supporting insulators, depending on the operating voltage. Because it uses no liquid insulating materials, it can be installed in several different positions, and is self-supporting. It requires no special platform, and only a protection against wind and weather. The baseplate mounts on many existing support structures without difficulty.
