About SPB / NSPB
In the same way as for coaxial ducts, separate or non-separated phase connections are used mainly for the evacuation of energy in power plants with a power of less than 100 MW but also for the supply of auxiliary equipment in power plants. as well as for high energy-consuming industries (paper mill, cement plant, refinery, etc.).
These medium-voltage (MV) connections, ranging from 1 to 24 kV, consist of phase conductors enclosed in a common metallic enclosure, separated by metallic screens between phases for the SPB version. Isolation is also provided through supporting insulators and ambient air between the conductors and the enclosure.
There are different variations in profiles (“flat” profile, “I” profile, “U” profile, or “square” profile) and materials (aluminum or copper) for the conductors, tailored to the specific needs of our clients.
