ROCCHETTI FAI DA TE “EI/UI“

L’utilizzo del nuovo brevetto “FAI DA TE” ha modificato il modo tradizionale di produrre i trasformatori riducendo i costi e semplificandone la costruzione.

Vantaggi

• Buona dissipazione al calore con effetto camino

• Alta resistenza termica

• Utilizzabile per tutte le misure

• Bassi costi di consumo

Prodotto in RP7 può arrivare a temperature elevate (vedi pag.5)

Utilizzando appositi distanziali si possono costruire innumerevoli misure a partire da 90 mm fino per arrivare a 190 mm utilizzabili sia per la colonna sia per il pacco lamellare. Per l’altezza si utilizzano stecche angolari in vetroresina 10×10 mm di lunghezza fino a 2.5 mt.

Ove non sia possibile usare i distanziali si può utilizzare una lastra di vetroresina. da inserire nelle apposite scanalature in modo da ottenere qualsiasi misura.

DO IT YOURSELF "EI / UI"

The FlexiFormer coil support system provides a cost effective and easy method of building large transformer coil supports tor cut core lamination widths 90mm to 190mm. The patented system consists of corner pieces, spacers and corner section profile which fit together to form a rigid structure upon which heavy windings can be produced.

Corner pieces are available in 90° or 45° profiles which offer alternative positioning of duct strips allowing for optimal air flow. Slot channels on the corner piece allow for duct strips to be placed in a fixed position. This eliminates the chance of the duct moving or falling out of the coil, maintaining the shape and integrity of the coil.

Up until now heavy windings have been produced by wrapping an insulation former around a winding mandrel. When the wound coil is removed from the mandrel there is the danger of the inside of the coil collapsing as there is nothing supporting it. Added complications can also come when trying to tit the coil onto the lamination stack with the possibility of insulation damage where the mis-shapen coil snags against the laminated core. This can lead to potential puncturing of the coil insulation heightening the risk of shorted turns and earth faults.

FlexiFormer ensures that the coil is supported and does not collapse during this transition from winding machine to core building.

Tue whole assembly is rated at temperature Class H UL94 VO and can be included in systems where high temperature and flame retardant materials are specified.
