An insulating link is a device used on the hook of a crane to protect the crane operatives from the danger of electrocution should the crane come into contact with a power line. Insulating links are essentially robust insulators and prevent the flow of electricity from bare, suspended wires through cranes and into personnel working near the ...
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.

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles .
Termination tower (overhead line to underground cable) Future termination tower of a 110 kV-line while joins are installed. A special kind of a dead-end tower is a termination pylon, also called a terminal tower. It is used when the overhead power line terminates, and is connected to substation equipment, or transitions to underground cable.
An insulator of a telephone transmission line A pin insulator ceramic plate used for 20 KV lines. A pin insulator is a device that isolates a wire from a physical support such as a pin (a wooden or metal dowel of about 3 cm diameter with screw threads) on a telegraph or utility pole.
EOT cranes are extensively used in warehouses and industry. [2] An EOT crane is able to carry heavy objects to anywhere needed on the factory floor and can also be used for lifting. However, it cannot be used in every industry. The working temperature is to limited to a range between -20°C to 40°C.
