Mozyrsalt needed to replace 0.4 kV of old low voltage panels with new panels within one of the workshop transformer stations, without the need to close down operation longer than necessary. Strict delivery time for the shelf equipment was the essential requirement for the project execution.
Mozyrsalt is the largest producer of vacuum-evaporated dietary salt in CIS and Western Europe. Its designed capacity is 360 thousand tons a year. The main line of the company’s activity is mining and production of extra evaporated dietary table salt. Extra salt “Polesie” is used for manufacturing other products. The assortment includes more than 50 products.
Mozyrsalt needed to replace 0.4 kV of old low voltage panels with new panels within one of the workshop transformer stations, without the need to close down operation longer than necessary. The project was initially oriented towards the application of MNS low voltage panels (ABB), however, afterward the prospective suppliers considered Logstrup- and Rittal-based manufacturers. ABB reserved the right to be the supplier of electric components.
Strict delivery time for the shelf equipment was the essential requirement for the project execution. Mozyrsalt production has a continuous process cycle, which involves only one annual interruption for 21 calendar days. During this period (1.5 weeks) a gap was scheduled to replace 0.4 kV switchgear within one of the workshop transformer substations. The scope of work not only involved the equipment installation, but also start-up and commissioning, including cable line test.
Type-tested switchgear that ensures operational reliability
The global partner who carried out this project is an authorized manufacturer of equipment based on the Logstrup Modular System in the Republic of Belarus. They prepared a complete scope of tender technical documentation (approximately 70 sheets containing the description of the panel design features, accompanied by wiring diagrams, installation and operation instructions). The brine atomizing test report (1000 hours) is a credible reason for using the Logstrup system; none of the other participants in the tender could guarantee similar parameters. Due to Logstrup efforts, as the assembly component supplier, and Logstrup partner in Belarus, all work was completed on time, without violation of contractual commitments. The design of the panels, rapid installation and serviceability were commended by Mozyrsalt maintenance staff.

Al Dar Properties
As part of reviving a historic landmark in Abu Dhabi –a central market known as the souq- our partner was tasked to supplying all low voltage requirements for Al Dar Properties' large real estate development. The task required modular and space-optimized solutions, as parts of the panels had to fit into limited space. Thanks to the flexibility of the Logstrup Modular System combined with the expertise of our partner, a customized solution was possible.
Theiss Thermal Power Plant
With a total effect reaching 800 megawatts, the thermal power plant in Theiss holds a significant role in bringing a consistent and reliable supply of power, gas and heat to the Northern part of Lower Austria. The power plant was built in 1974 and consists of two units. In one of the units, the control gear needed a complete renewal in 2008.
Sleaford Renewable Energy Plant
Logstrup is supplying cabinets for the main supply and distribution for substations for 400V and 690V AC and Control Boards for Boiler, Common auxiliaries, Building services, Steam auxiliaries and Straw handling. In total 280 modules of cabinet.
The Great Belt link
Logstrup will supply high-quality low voltage solutions for the Great Belt Link (Storebæltsforbindelsen) in 2020. In 1991, Logstrup was tasked to supply the first electrical switchgear for the tunnels, and they have worked flawlessly ever since.
National Bank of Serbia
The National Bank of Serbia supports all financial- and transactions in Serbia. Consequently, renewing their 30-year-old switchgear required efficient work during limited hours in order to secure up-time.
