Metal pole with the bent structure have some of advantages in compare with ferro-concrete pole:
Using of the metal poles effectively for regions of the Far North where spring-autumn cycles of thawing and freezing of a moisture in structure of concrete because of the big daily temperature differential result in destruction of reinforced concrete poles.
The patent protects the design of metal poles. Patent N° 34192U1, it is published 27.11.03, BI No.33).
ILLUMINATION MASTS AND LIGHTNING CONDUCTORS

MULTIPHASE WELDING RECTIFIERS MSV
For high quality of a welded seam at electric welding three-phase welding rectifiers of a Russian-made production (e.g. VDU-250) and foreign manufacture (e.g. ESAB LHF-250), which basis is made with traditional three-phase transformers and three-phase bridge rectifiers, are widely used.
Essential lacks of such welding rectifiers are low values of efficiency and factor of capacity, the big level of pulsations of the straightened voltage and nonlinear distortions of a voltage of a power line.
The abovementioned lacks of the welding rectifiers cause unfairly high losses of power resources at performance of welding works, negative influence on quality of electric energy of a power line, demand high qualification of the welder at performance of welding works and, as a rule, are one of principal causes of poor quality of a welded seam. Substantially these lacks can be eliminated due to use of multiphase welding rectifiers MSB. The basis of them is made with the transformer with rotating magnetic field (TVP), which design essentially differs from a design of usual three-phase transformers and allows creating rectifiers with phase nature of straightening from 12 up to 30.
Welding rectifiers MSB in comparison with analogues differ:
