CHARACTERISTIC
Functional and reliable e²ALPHA switchgear belongs to the group of modern, four-compartment indoor MV switchgears suitable for wall- or self-standing installation. The standard range of e²ALPHA consists of cells with a width of 400, 600, 750 and 800 mm. The high degree of operational safety for e²ALPHA switchgear was achieved by applying an extended system of mechanical and electrical interlocks as well as reinforced mechanical cell construction characterized by a high level of arc resistance.
CELL DESIGN
Switchgear cell is made of prefabricated steel plates and Al- Zn with thickness of 2 and 3 mm. In the areas particularly exposed to internal arcing and pressure of arcing gases has been applied high-quality steel sheet with a thickness of 3 mm with powder ink coating. Additionally, in the case of the cells made in arc resistance 31.5 kA /1 , the door of cable compartment and withdrawable module has been provided with additional reinforcements and screens.
ADVANTAGES OF THE e²ALPHA SWITCHGEAR
APPLICATION
e²ALPHA switchgear is an ideal solution for industrial-, distribution- and mining power companies. Advanced design combined with reliable interlocks makes e²ALPHA ideal for applications in the strategic areas of power system where the highest reliability of power supply is required (eg. MPS-Main Point of Supply, power plants and mines).
