Efficient and completely safe distribution of three-phase alternating current with power frequency of 50 and 60 Hz with voltage 6 and 10 kV in any situation is the main purpose for which the complete device of KRU-SESH-59 (KRUN) model is intended. Due to the peculiarities of its modular construction it can operate in open pit mines, drilling installations and other hard-to-reach objects in the severest climatic conditions. Several decades of experience for the equipment creation similar to KRUN 6, 10 kV help now Electroshield Samara to produce the equipment that was recognized not only in Russia but also abroad.
But we are convinced that only experience is not enough nowadays. That is why the cubicle K-59 KRUN incorporated lots of innovative technologies and solutions, thereby a variety of important advantages are ensured to you as a user. The most significant among them are the following characteristics:
Do not look for other options – order KRU-SESH-59 from us today! We guarantee that switchgears produced by Electroshield Samara will satisfy all your expectations and it will be difficult to find more attractive quality-to-price ratio for KRUN.
Highly prefabricated product within the limits of transport units.
Minimum scope of work and costs for installation works on site.
Provision with forced ventilation, electric convectors, thermal curtains, air conditioners and split systems to create optimal working conditions for maintenance personnel (upon customer request).
Possibility to transport on the sledges of the factory construction and production, for example, within oil and gas regions or extractive open pit mines including the possibility to use the sledges as a foundation during operation (upon customer request).
Availability of brackets for overhead entries with rigid busbar preventing mechanical influence on the bushing insulators from the flexible busbar of the substation 6(10) kV side.
Availability of the device of OPU-SESH-59 type for low voltage equipment including without limitation to the equipment with intolerably large dimensions in depth when placing them in KRUN control aisle.
