PURPOSE
The Low Voltage cabient of the Stage Transformer Station is intended for the distribution of electricity from the medium-voltage overhead network. Applies to distribution networks with nominal voltage 230/400 V AC and 50 Hz frequencies. Designed for external mounting.
ENCLOSURE
The cabinet enclosure is made of 3 mm thick aluminum sheet, protected from corrosion and it prevents the entry of rainwater. The cabinet has an opening door on the front and rear side with the possibility of installing the half-cylinder type lock. It has cable entries at the top and at the bottom of the cabinet. The dimensions of cabinets, as well as the layout of individual elements are aligned in terms of airspace and sliding paths and provide easy and secure connection.
INSTALLATION
The cabinet is fastened to a four-point transformer station with screws on the underside of the existing L-profile of the iron-lattice transformer station. Such installation allows easy manipulation with low voltage devices.
EXECUTION
It is a 3 mm thick aluminum sheet cabinet with doors on both sides. The electricity consumption meter for public lighting is set on the universal counter plate. All types of standardized counters can be set, from single-phase to three-phase electronic counters with built-in tariff device. The fuse-disconnector (strip) can be sealed in the closed and open position.
QUALITY
Has a CE quality mark, top quality, tested and certified in accordance with the requirements and regulations of the relevant European standards and laws.
