HPC Series LV Power Capacitors
The HPC series low-voltage power capacitors are designed for reactive power compensation and passive filtering applications in low-voltage distribution systems up to 1,000 V. Featuring reliable safety protection, low losses, and efficient thermal performance, they provide stable operation and long service life.
Product Description
The HPC series adopts self-healing dielectric technology, pressure-sensitive disconnection, and dry-type epoxy resin insulation to provide triple safety protection. Designed for use with reactors in tuned filter circuits, it is widely applied in low-voltage compensation cabinets, distribution rooms, and systems with concentrated inductive loads.
