Main performance and characteristics
- Absorb and impair circuit harmonics and purify electric circuit harmonics and purify electric circuit as well.
- Prevent voltage excessively for electric circuit and induced fulminous. Impingement repeatedly.
- Energy saving, improve power-factor and lower maintenance costs of hi-tech electrical equipments.
1. Low loss, good self-healing performance, low temperature rise, longer life;
2. Adopted the most advanced manufacturing process, enhance dielectric resistance, lowest capacity loss, maintain excellent and stable electrical performance althought move in a long time;
3. Aluminum case, firm and rustless, heat dispersion is superior to other materials;
4. Brass bolt terminal design in reason, avoid short-circuit, terminal lead connection is well;
5. Leak-proof structure, build-in security protector, a unique sequential protection system ensure safety of using;
6. Easy and compact installation.
7. Adoption of European structures and tensile explosion-proof technology ensure higher security
Operation of internal protective device
In the event of internal failure of aging at the end of the capacitor's operational life, an increasing number of self-healing breakdowns may cause rising pressure inside the capacitor element. To prevent it from bursting, each capacitor element is designed with internal pressure sensitive interrupter (Protective Device). With rising pressure the cover will bulge to disconnecting copper taps at weak points from the cover, and the current path is interrupted irreversibly to avoid the relative disaster.
