Product introduction：
The product combines coupling capacitor and filter into a whole and is used in medium voltage distribution line carrier communication system.The high-voltage end of this product is directly connected to the medium voltage distribution line through the high-voltage cable, the low-voltage end is connected to the carrier machine through the high-frequency cable, and the grounding terminal is grounded through the grounding wire, which is used to transmit carrier signal and isolate power frequency current.
Comply with standard：
·IEC 60481:1974,NEQ《Coupling devices for power line carrier systems》
·IEC 60358:1990,MOD《Coupling capacitors and capacitor dividers》
Service conditions
·Installation environment：Outdoor
·Environmental temperature：-30℃~+80℃
·Working frequency：50Hz&60Hz
·Altitude：1000m（Confering with consumer if above 1000m）
