High-voltage direct current - Wikipedia high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems.. Most HVDC links use voltages between 100 kV and 800 kV. A 1,100 kV link in China was completed in 2019 over a …
Thermal insulation - Wikipedia insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
SF6 Gas Insulated Transformers - MEPPI 1500kVA SF6 Gas-Insulated Transformer Mitsubishi Electric Power Products, Inc. (MEPPI) supplies SF6 gas-insulated transformers for applications where a non-flammable, non-polluting transformer is desired, such as in densely populated areas, inside buildings, and in areas near lakes and rivers where potential oil leakage from a conventional transformer would be harmful to the environment.
