High-voltage power line communication coupling systems are key equipment for implementing power line carrier communications. Their core function is to efficiently couple high-frequency communication signals while safely isolating the power frequency high voltage. In this sophisticated system, high-voltage doorknob capacitors, with their superior electrical performance and reliable structural design, serve as an indispensable "frequency selector" and "insulation barrier" in the coupling circuit.

In PLC systems, coupling devices face two core challenges: first, they must withstand power line voltages ranging from several thousand to tens of thousands of volts to ensure absolute safety for back-end communication equipment; second, they must achieve low-loss signal transmission within the carrier frequency range (typically 40-500kHz). Our high-voltage door handle capacitors, through their unique design, perfectly address these technical challenges. Their specialized ceramic dielectric and vacuum epoxy potting process ensure stable insulation performance across voltage levels of 35-500kV. Their low equivalent series resistance (ESR) and low inductance (ESL) ensure excellent frequency response within the carrier frequency range.

As a core component in the coupling circuit, our high-voltage door handle capacitors fulfill the dual duties of high-voltage isolation and high-frequency coupling. Their exceptional temperature stability (capacitance change of less than ±2% from -40°C to +85°C) and long-term reliability ensure stable operation of PLC systems in a variety of harsh environments. Choosing our products ensures you've chosen the most reliable technical support for your power communication system.
