LV switchboards 0.4 kV
Distribution of electrical energy from the transformer substation to the end consumers.
Low-voltage switchboards 0.4 kV
Depending on the needs and the nature of the load, these switchboards distribute electrical energy from the substation to the end consumers. As additional sections, they can include a reactive power compensation section or a street lighting section.
They always consist of an incoming and an outgoing panel, while the compensation panel and the street lighting panel are optional.
Incoming panel
The incoming panel is connected directly to the LV side of the transformer and is equipped with a moulded-case circuit breaker matched to the transformer rating. It also contains instruments for reading the voltage, the present load current and the maximum load current. Fixed no-load compensation for the transformer or an additional outgoing feeder can be fitted in the incoming panel.
Outgoing panel
The outgoing panel is supplied as standard with 8 outgoing feeders of 400 A, usually with insulated fuse rails, fuse bases or three-pole fuse switch disconnector strips.
