Specialized in design and manufacture of Busbars Low & Medium Voltage

Created in 1995

Born of a need of electric connections for the routing of the power of devices made by Bernard & Bonnefond, she turns little by little to a wider public.

Busbars made by Amppelec are developed and totally adapted to the specificities of the installations of our customers.

MODELS OF CALCULATION

The following examples shows a single phase realization. 3 modelizations demonstrate the importance of the disposal of the phases in a busduct. It influences the distribution of currents. Subtransmission N

1: measure : A-A-R-R Subtransmission N

2: measure : A-R-A-R Subtransmission N

3: measure : A-R-R-A A → Phase 1 or "to go" R → Phase 2 or "return"

Effects

Investment in a 3D software - Better display of plans for the customer. - Better ability to react for the realization studies. - Standardization of plans. - New connections - Decrease of the number of bolts. - Passage of the bolts in M12 type - Nuts gone up
