Main advantages

Maximum Safety

High reliability and quality of Prefabricated Substation

Prefabricated Substations design capabilities

Convenient operation

Monitoring, diagnostics and control

Low total cost of ownership

01 Maximum Safety

A design that provide safe connection of cable and overhead lines, connections of switchgear with transformers, reliable systems of mechanical and electrical interlocks, internal rigid separation of the switchgear into compartments and Isolation of short-circuit faults within one compartment of the cabinet will provide the top level of personnel safety during B(M)PS equipment maintenance and repair.

02 High reliability and quality of Prefabricated Substation

Medium voltage switchgear ELTEMA 6(10)-35 kV used in ELM B(M)PS 35 kV has been developed taking into account the specifics of operation at power facilities located in Russia and other countries. The resulting reliability of its structural design has been proven by tests carried out by independent test centers.
The specially developed design of power units using high-quality components and an efficiently organized manufacturing process allow us to provide the Customer with reliable ELM B(M)PS electrical equipment which suits for any special project requirements.

03 Prefabricated Substations design capabilities

Detailed technological design development of the product makes it possible to manufacture various types of Prefabricated Substations: block-type, with outdoor power transformers. This type will allow you to place a set of detached switchgear buildings and outdoor transformers (BPS) or an indoor modular type, which allows you to arrange all equipment in transport modules of high prefabrication (MPS).
The reinforced all-welded steel structure of the B(M)PS provides 100% rigidity of the modular building modules and very easy to transport and installation of the modules on various foundations.PS provides 100% rigidity of the modular building modules and very easy to transport and installation of the modules on various foundations and the modular construction principle makes it possible to optimally use the space for the B(M)PS installation.

04 Convenient operation

The design of medium voltage switchgear ELTEMA 6(10)-35 kV used in ELM B(M)PS 35 kV ensures a quick access to current transformers and cable connections while enabling expansion connections of the main circuits that do not require maintenance during operation.
A dynamic symbolic chart showing statuses of the switching devices and positions of withdrawable units and earthing blades as well as inspection windows on the front walls of the cabinets make all operations with the switchgear clearly visible. Smart visual stickers on the front walls contain brief local guidelines for the personnel to facilitate switching and maintenance operations on the switchgear.

QR-codes are provided on the front walls of our cabinets for quick personnel access to the technical documents and the support center contact number.

05 Monitoring, diagnostics and control

B(M)PS is directly integrated with APCS and remote control systems of plants, automated dispatch control systems, adaptive distribution management systems (ADMS) and other data analytics systems using the comprehensive list of data protocols including IEC 61850.
The control and monitoring system of B(M)PS supports diagnostics and equipment performance data transfer to the maintenance and repair system to enable on-site preventive equipment maintenance.

06 Low total cost of ownership

We leverage special prices for components by leading Russian and global manufacturers, our own machine fleet and a short production cycle to offer the best ELM B(M)PS price to our customers. Low maintenance frequency along with minimized costs and prolonged service life help to minimize the total cost of ELM B(M)PS ownership
