The modular three-phase capacitors are designed to compensate
industrial networks in low voltage. Their installation and assembly
is easy thanks to the modular design. Due to their construction
within a burst proof sheet steel external case, this allows optimum
heat dissipation. Inside there are three single-phase units, which
are equipped with pressure sensitive disconnectors.
In addition to this construction, the self-extinguishing properties
of the materials used for the insulators and the protective cap
represent a good safety-device against possible bursting.
Les condensateurs modulaires represented la solution ideate
pour la compensation de charges. Leur installation et assemblage
sont tres facile parce-que ils sont modulaires. Le boftier exterieur
est realise en tole acier, afin de beneficier d'une tres bonne
dissipation de la chaleur. A I'interieur il y a trois unites
monophasees, chacune equipee d'un systeme anti-eclatement.
En ajoutant a cette construction des parties isolantes et un capot
en matiere auto-extinguible on garanti un bon dispositif de non
propagation de la flamme.
