Technical Features

Low voltage paralleling capacitors, with rated voltage at or less than 1000 V, are in strict accordance with national standard GB3983,1-89. Hihg voltage paralleling capacitors with rated voltage higher than 1000V are in strict accordance with national standard GB/T11024,1-2001, which is equivalent to the international standard IEC60871-1:1997).

Installation conditions: -40 - + 45 under general cimatic conditions; allowed altitude: no greater than 2000m for low voltage capacitors and no greater than 1000m for high voltage capacitors.

Capacitance tolerance for capacitors should be within the range of -5% - +10% of the rated value.

At the rated line-frequency voltage, the consumptive angle tangent value of capacitors at 20 centidegree:

(1)low voltage film and paper capacitor: no greater than 0.0022;

(2)high voltage film and paper capacitor: no greater than 0.0012;

(3)hihg voltage film paralleling capacitor: no greater than 0.0005.

Capacitors can run over a long time under working voltages, maximum of which is no greater than 1.1 times of the caacitor rated voltage.  

Capacitors can run over a long time under working current no greater than 1.3 times of the capacitor rated current., caused by increased voltage and uppper harmonic waves.
