Specifications
Low-voltage dry-type capacitor is used the most advanced all-metal polypropylene film as raw material, introducing foreign advanced technology Technique and equipment production accordance with national standards IEC in strict , mainly for low-voltage power grid to improve power factor, reduce reactive loss and improve power quality.
Main features:
(1)Self-healing
excellent self-healing properties, using the most advanced full-metal polypropylene film as the medium, if the medium be damaged, the metal electrode around this damage points in an instant incurs volatile disappear, and immediate resumption of insulation, so that the capacitor recover and continue normal operation.

(2) low loss
The actual value less than 0.1%, so the capacitor has low energy consumption, less heat, low temperature, long life , good of energy saving.

(3) security
In line with GB, IEC standard, protection devices installed in a single-capacitor attached to the internal; when an exception occurs in a circuit or single-capacitor , the protection device will be an immediate action, automatically cut off power to prevent a secondary disaster. Attached to the discharge resistor, to ensure safety of electricity and maintenance . Shell made of pressed steel, painted lacquer baked high temperature inside and outside which has good weather resistance ability, so it has high security.
