| Characteristics elements | Zvar® modular capacitor |
|---|
| Enclosure | Non-flamable and auto-extinguishing Poliamide in V0 flamability class |
| Need to be grounded | No - double insulation - class 2 |
| Dielectric / Winding | Polipropylen film, Alu-zinc metallized |
| Impregnant | Totally dry, cast resin technology |
Overpressure operating
(anti-explosion system) | By operation of an overpressure device inside the enclosure
(flexible membrane, that disconnects normalized fuse link)) |
Capacitor and enviroment
hazard | No risk because:- totally dry
- external deformation does not appear
- enclosure and resin are auto-extinguishing in V0 class
|
| Ambient temperature class | -40 do +55°C |
| Permitted casing temperature | 90°C |
| Average temperature on 24h | 45°C |
| Watt losses (in heat) | <0,3W / kvar (internal resistor included) |
Maximum admissible voltage
- according to standard IEC 60831-1 i 2 | Ucn + 20% 24h/24h
Ucn + 25% 18h/24h
Ucn + 30% 12h/24h
Example Ucn = 440V + 20% = 528V 24h/24h - Permanent |
| Maximum admissible current | 1.5 ln |
Tested with voltage
(terminal to terminal) | 2,15 Un AC 10sec. |
TTested with voltage
(terminal to enclosure) | 6kV AC 1min
15kV AC 1,2/50μ sec. |
| Statistical life expectancy | >130 000h |
| Mounting position | Any position, because dry resin impregnan |
