01 Maximum Safety

Reliable systems of mechanical and electrical interlocks, internal rigid separation of 35 kV switchgear into compartments and Isolation of short-circuit faults within one compartment of the cabinet will provide the top level of personnel safety during equipment maintenance and repair.

02 High reliability and quality of products

Medium voltage switchgear ELTEMA+ 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. 
Thanks to the wide range of main circuit arrangements that include high quality components and an efficient set up of the production process, we can offer our Customers reliable electrical equipment suited to any specific project requirements.

03 Convenient operation and maintenance

The design of the Eltema+ MV switchgear provides a quick access to cable connections, has a voltage transformer with an integrated truck, a current transformer with an integrated truck inside each cabinet MVS, and also provides for main circuit connections with thermal expansion stabilization that do not require maintenance during operation.
A specially designed easily controlled service truck makes it easy to roll a heavy circuit breaker into the service area.
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.

04 Convenient switching

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.

05 Monitoring, diagnostics and control

Medium voltage switchgear ELTEMA+ 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 wide list of data comminication protocols including IEC 61850.
The control and monitoring system of medium voltage switchgear ELTEMA+ supports diagnostics and equipment performance data transfer to the maintenance and repair system to enable on-site preventive equipment maintenance. 
Medium voltage switchgear ELTEMA+ can house motorized drives and supports remote control of power switches, withdrawable units and earthing blades with video monitoring of their positions.

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 equipment price to our customers. Low maintenance frequency along with minimized costs and prolonged service life help to minimize the total cost of medium voltage switchgear ELTEMA+ ownership.

Dear Valery Vladimirovich!

 

Since 2014, investment projects and projects for the intensification and technical re-equipment of existing production facilities have been implemented in PJSC Acron, Veliky Novgorod. In particular, the projects "Increasing ammonia production capacity to 2,300 tons/day", "Increasing carbamide production" have recently been implemented, carbamide granulation plants No. 1 and 2, a calcium nitrate production workshop, and others have been built and put into operation.

 

Medium-voltage (Eltema MVS) and low-voltage (LVS Assol) equipment manufactured by JSC Electronmash has been supplied and put into operation at all facilities. The total number of equipment supplied at different current and voltage levels has exceeded 10 units in the last three years alone. 

 

The delivery was carried out in compliance with the established contractual deadlines.

 

There were no complaints about the quality and completeness of the delivery. During the operation of the Eltima control unit and the Assol Control Unit, it proved to be convenient in daily operation and reliable equipment that fully meets the operational requirements adopted at our enterprise. The specialists of PJSC Acron highly appreciated the quality of products and the service provided by the employees of JSC Electronmash during the installation of equipment at the facility.
