Moscow city services are developing and implementing unique equipment. A robotic technological complex has been introduced into the production cycles of Mosgaz JSC products. It performs automatic plasma cutting and welding of tubular parts using a laser system to adjust the welding path and monitor digital parameters in real time. An underground transformer substation was designed at Rosseti Moscow Region PJSC. This is especially relevant for the implementation of projects in the historical center of Moscow. The solution is currently in the development stage, and its pilot use is planned in the future. PJSC "MOEK" has started pilot-industrial operation of the new "Filin-95" adapter leak detector. The complex is designed to accurately determine the location of pressure drops in pipelines at an underground facility. The device operates on the basis of analyzing sound waves generated by a leak. JSC Moslift has started using a modern crane installation with a vacuum mechanism of Russian manufacture in its own production. Local development makes it possible to optimize the most labor-intensive process - the manipulation of metal weighing up to one ton. United Energy Company JSC is implementing a single accurate time system, which is necessary for the efficient operation of all technological systems of the company's energy facilities. It is based on a clock based on the hydrogen frequency standard. The device is able to autonomously maintain a time scale for a long period - from several months to several years.
