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 ...
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.
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 ...
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 .
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. [citation needed]
An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...
