Alpivar: the vacuum technology capacitor
 DESIGN
Alpivar patented capacitors are totally dry units with no impregnation or insulation liquid.
They are designed by assembling individual single-phase coils, coupled in a delta arrangement
to obtain a three-phase unit.
The coils are produced from two films of polypropylene with zinc plating on one side:
All coils are then coated under vacuum into self-extinguishing thermoset
polyurethane resin which forms the casing, providing mechanical and electrical
protections.
ALPES TECHNOLOGIES’ unique vacuum potting technique ensures that Alpivar
capacitors have excellent resistance over time and much longer service life than
conventional units.
Vacuum potting ensures that no air or humidity remains close to the coils after
coating. This design provides excellent resistance to overvoltages and partial discharges.
Furthermore, the unit complies fully with environmental protection requirements (no PCB). No insulation
or impregnation liquid is used in the Alpivar capacitor.

PRESENTATION
Monobloc or modular, Alpivar capacitors meet all user requirements. The modular version in
particular can be quickly and easily assembled to produce units with various power ratings, enabling
integrators and distributors to make significant savings on storage costs.
INSTALLATION
The compact format simplifies installation and significantly reduces cubicle or rack costs. The
casing is particularly resistant to all solvents and atmospheric agents (rain, sun, salty air, etc.). |

Alpivar capacitors are thus particularly suitable for installations:
• outdoors (on poles)
• in a corrosive atmosphere

CONNECTION
-
the terminal blocks are easily accessible
on the top of the unit, making Alpivar capacitors particularly easy to connect
-
the use of socket-type terminals enables
cable and eye connections to be made directly to the unit’s
various ranges
-
Alpivar capacitors are double-insulated
or class 2 units, which do not need earthing.
