Switchboard manufacturing

An important part of our program is the production of low-voltage (LV) switchgear, including serial production. We ensure the qualification of switchgear according to customer requirements (seismicity, magnetic field, vibration, aging, EMC, ...). We produce switchgear in classic and modular (withdrawable) versions and we are an official SIEMENS partner for the production of Sivacon S8 cabinets.

On an area of ​​almost 3000 m2 there are production facilities, a mechanical workshop, a testing room, warehouse and administrative premises.

WITHDRAWABLE DISTRIBUTORS
Withdrawable switchboards represent a modern trend in the design of switchboards for indoor environments. They are primarily intended for withdrawable design, but they can be made in fixed or combined versions. They are mainly used in applications with continuous operation or in places where maximum emphasis is placed on the functionality of the system with the shortest possible time to eliminate possible faults, without the need to shut down the entire switchboard.
SECURITY
When designing withdrawable switchgear, great emphasis is placed on the personal safety of the operator:
arc flash protection system (exhaust dampers above the main bus system, gas extraction from fixed and withdrawable blocks, partitions between individual fields, additional door locks, etc.)
blocking of pull-out modules against pulling out when switched on
module test positions
The internal protection of the switchgear, even after removing the withdrawable blocks, is IP20.
BENEFITS
quick replacement of the pull-out module
elimination of a fault on the outlet without the need to shut down the entire switchboard/system
high operating safety
possibility of testing the outlet without operating restrictions
possibility of modifying the outlet without the need to restrict operation
maximum clarity

SOLID CONSTRUCTION DESIGN
Cabinet-type switchboards meet all the requirements of STN standards for the production of low-voltage electrical distribution equipment. They are also designed for applications requiring seismic resistance, or for projects requiring atypical cabinet dimensions, e.g. retrofits.

The switchboard equipment is installed in empty cabinets, which allows for the creation of complex assembly units, high variability of equipment content, as well as modular design.
BENEFITS
variable arrangement of the instrument filling
possibility of modular design
it is possible to produce cabinets of atypical dimensions according to customer needs / Retrofit
possibility of a special welded construction that is optimized for resistance to seismic effects and vibrations
design for outdoor and indoor environments
VARIANTS
Single-leaf, double-leaf, double-sided.
Cabinets can be made according to the customer's wishes - with glass doors, side and rear covers, mounting panel, instrument grid, rotating frame for 19" or 12" mechanics, pedestal, lighting, door locks, document box, etc.

WALL-MOUNTED DISTRIBUTION BOXES
Wall-mounted distribution boxes are intended for surface or flush mounting, or mounting directly on the structure of technological equipment. The area of ​​application of wall-mounted distribution boxes is very universal due to their compact dimensions and variable instrumentation, which is always defined according to the individual needs of the customer. Wall-mounted distribution boxes meet all the requirements of STN EN standards for the production of low-voltage electrical distribution equipment.
