Block-modular low-voltage complete power distribution units
Block low-voltage complete units are low-voltage complete units (LVDU) built into an insulated or uninsulated block box.
Block low-voltage complete units are designed for control, protection, signaling, reception and distribution of electric power of three-phase alternating current of industrial frequency 50 or 60 Hz in power supply networks of industrial, oil and gas producing and processing enterprises and other facilities.
Detailed information
Product composition
Modular low voltage switchboard consists of pre-fabricated modular buildings with the equipment installed in it. The configuration of modular low voltage switchboards equipment is determined by the customer and project design and usually includes:
- low voltage switchgear;
- substation service equipment;
- equipotential terminal box (optionally);
- HVAC and lightning;
- security and fire alarm.
Low-voltage switchboards are manufactured in accordance with the requirements of technical specifications, GOST R 51321.1 and the customer's design documentation.
Type of the product and its configuration is determined by the customer and the project design.
Low-voltage switchboards have a frame structure made of bent sheet profiles with switching and protection equipment and electrical measuring instruments installed in them. According to the construction specifications the low voltage switchboards can be divided in:
- front access switchgear;
- dual access switchgear;
- single row switchgear;
- double row switchgear.
The power is supplied via a cable connected from below or above the switchboard. It is connected to outgoing lines from below using the cable. The power cable and outgoing line cables are connected through the terminal box.
