Utilizing a special type of metallized polypropylene construction, completely impregnated with a non-PCB fluid sealed in a steel case, Steelman capacitors are superior in performance to all other standard capacitor cells.
Capacitor Standards require a life expectancy of 60,000 hours which equates to 20 years based on 8 hours per day of operation. Capacitor life is degraded based on over voltage, over temperature, or harmonic conditions.
LOW ENERGY CONSUMPTION:
Because of the metallized film construction of the capacitor cells, energy losses are reduced, thereby lowering the operating temperature, which in turn extends the life of the capacitor. Losses due to dissipation are generally less than one tenth of one percent of the rating of the KVAR unit.
Each capacitor cell has self healing characteristics, which in the event of a dielectric breakdown will vaporize the defects and clear the fault. This feature works without damaging the dielectric structure or resulting in any significant loss of capacitance.
Each individual capacitor cell has an external discharge resistor which will reduce the residual voltage to less than 50 volts within one minute after the capacitor is disconnected from power.
SINGLE PHASE CELLS:
Steelman KVAR units utilize single phase capacitor cells wired in a delta connection for three phase operation. This construction permits maximum heat transfer from each capacitor cell enhancing capacitor life and allowing for individual cell replacement which results in lower maintenance costs.
PRESSURE SENSITIVE INTERRUPTER
Each Steelman capacitor cell has as part of its construction a pressure sensitive interrupter. The interrupter detects the build-up of gas pressure within the capacitor causing the metal case to bulge out. This disconnects the internal connections, effectively removing the capacitor out of the circuit before a rupture can occur . The pressure sensitive interrupter is UL recognized and each capacitor cell is individually UL listed.
