2. Bushing (electrical) - Wikipedia

   en.wikipedia.org/wiki/Bushing_(electrical)

   Insulated bushings can be installed either indoor, or outdoor, and the selection of insulation will be determined by the location of the installation and the electrical service duty on the bushing. For a bushing to work successfully over many years, the insulation must remain effective both in composition and design shape and will be key ...

3. Groundbed - Wikipedia

   en.wikipedia.org/wiki/Groundbed

   For building electrical grounding systems or earthing systems, there is a low resistance conductor bonding the metalwork and this is connected to a groundbed. The electrodes for electrical grounding are often called ground rods and are often made from steel with a copper clad surface – typically 1 to 2 m long and 20 millimetres (0.79 in) in ...

4. Pothead - Wikipedia

   en.wikipedia.org/wiki/Pothead

   A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers. [1] Its name comes from the process of potting or encapsulation of the conductors inside the terminal's insulating bushing.

5. Isolated-phase bus - Wikipedia

   en.wikipedia.org/wiki/Isolated-phase_bus

   In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant. Isolated phase bus during installation at the Bui Dam Ghana ...
