MV switchgear

The UNIBLOK X-AIR medium-voltage air-insulated switchgear is designed for operation in distribution networks of industrial and utility power systems.

The switchgear is equipped with modern GSec Air (ABB) three-position air-insulated disconnectors.

Function: Secondary distribution of alternating current at a frequency of 50 Hz, with a rated voltage of up to 24 kV. Individual switchgear systems are configured from standard single bays with various equipment configurations. It is also possible to manufacture custom bay layouts. If bays with equipment not listed in this specification or with modified dimensions are required, the scope of equipment should be agreed upon with the manufacturer

The Uniblok X-AIR medium-voltage switchgear is intended for use in:

transformer substations,
distribution networks,
photovoltaic farms,
wind power plants,
industrial facilities,
public utility buildings.

Switchgear Bays Have the Following Features:

compact external dimensions relative to the rated voltage, specified insulation level, rated busbar currents, and short-circuit currents,
two-compartment bay design ensuring separation of the main busbar section from the section used for connecting power cables,
high operational reliability,
long service life without the need for extensive maintenance,
high corrosion resistance,
versatility in implementing various switchgear configurations, with any number of bays,
use of modern, reliable switching devices such as disconnectors, isolators, VD4/R circuit breakers, or circuit breakers from other manufacturers,
prepared for the installation of modern protection and control equipment,
possibility of wall-mounted installation, allowing efficient use of the switchgear room, which is particularly important in modernization and expansion of existing substations,easy and quick access to switchgear equipment for supervision and maintenance

The UNIBLOK X-AIR switchgear complies with the following standards:

PN-EN 62271-1 – "High-voltage switchgear and controlgear — Part 1: Common specifications,"
