Possibilities of circuit solutions

Compliance with industry requirements

Ease of operation

Constructive capabilities of cabinets

Implementation for digital PS

Unification of control cabinets

01 Possibilities of circuit solutions

All free discrete inputs and outputs are duplicated on terminals for organizing the collection and transmission of information to the ACS. And the cabinets are equipped with service power sockets and remote network connectors. This allows connecting laptops for parameterization and testing complexes. The ability to install a "dark plus" increases the resource of indicator lamps. The use of intermediate relays only in shutdown circuits and minimal use of resistors increase the overall reliability of the cabinets.

02 Compliance with industry requirements

We use the best available technologies of leading Russian and foreign manufacturers of relay protection and automation equipment and emergency control systems. Extensive experience in developing and supplying cabinets to large industrial and energy facilities also allows us to manufacture equipment that fully meets the special industry requirements of our customers.

03 Ease of operation

The division of the cabinet volume into zones with ergonomically placed groups of similar electrical devices increases the ease of use. And transparent overviews provide easy control over the status of the indication, operational and mode keys.

The presence of a mnemonic diagram on the cabinet facade and light indication provide visibility of the operations performed. QR codes placed on the cabinet facades provide quick access for personnel to technical documentation for the equipment and contact numbers of the technical support center.

04 Constructive capabilities of cabinets

The construct allows for the manufacture of cabinets of any overall dimensions. And the ability to place functional devices in different sections of one cabinet simplifies the installation of equipment, operation and allows for the implementation of projects with strict requirements for the dimensions of secondary system cabinets, significantly saving space in the control room. Rotary mounting plates provide quick and convenient access to the controls and terminal blocks of the cabinet in single-sided service cabinets. Double-leaf doors and structural division into service zones facilitate the work.

05 Implementation for digital PS

Relay protection and automatic equipment cabinets can be manufactured either according to the manufacturer's own construct documentation or according to standard FGC UES projects for digital substations. And the ability to test all equipment and verify information interaction according to IEC 61850 protocols at the manufacturer's plant significantly reduces the duration of commissioning work at the facility.

06 Unification of control cabinets

The use of a unified structural system of cabinets for secondary systems such as relay protection and control systems, automated process control systems, telemechanics, communications, and electricity metering makes the appearance of the control center integral and aesthetic. And the use of unified indicator lamps, keys, buttons and other controls makes spare parts sets uniform and facilitates their use.
