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 ...
Specification No. 70 Multiple Girder Cranes; Specification No. 74 Single Girder Cranes; Specification No. 78 Professional Services - This sets the standards for those who inspect, repair, design, and otherwise manage the supply and use of overhead cranes. Specification No. 79 Crane Operators Manual [3] Overhead Crane Inspection and Maintenance ...
In practice, for radio antennas, guy-wires, overhead power lines and most other loads, the strain insulator is usually in physical tension. [1] When the line voltage requires more insulation than a single insulator can supply, strain insulators are used in series: A set of insulators are connected to each other using special hardware. The ...

Some 2,700 employees develop, produce, and market components and all-in-one solutions for all interfaces in the areas of low voltage, medium voltage, high voltage, and extra-high voltage.
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 .
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.
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.
Four wool spinning machines driven by belts from an overhead lineshaft (Leipzig, Germany, circa 1925) The belt drives of the Mueller Mill, model and reality, in motionA line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century.
