Main characteristics:
1. small physical volume,light,wooden blocks type construction, gearing is convenient. Because of the usage metals polypropylene pellicle as the conduct, the physical volume, weight only 1/4 with 1/5 compared to the old product, it is the best product for electric motor powerless on- the- spot compensating.
2. low exhaustion: Physically worth is lower than 0.10%, therefore capacitor itself can energy-use is low, and have no heat, the temperature rise is low, the work life span is long, the energy-saving result is good.
3. good self-healing function: it can self-heal quickly to recover to the normal work after being broken by sudden electric currency
4. Safety: The inside placed electric resistance device. When the electric capacity occurrence break down, insurance device can on time break to open the power supply, and avoid the further development that break down, and insure the usage safety.
5. Gastight electricity: This electric capacity adopt the half of forerunner solid immerse ,the melting point higher than 70 ¡æ, during the use of the gastight oil , it can avoid the pollution of the environment, capacitor also can't be wasted because of losing the oil .
