Coupling devices are intended for Phase-Ground or Phase-Phase / Inter System connection of PLC terminal to high voltage power lines or power cables.
Main features
- Modularity and flexibility
- Total protection of equipment and personnel
- Compact design and aluminium housing offer high reliability and easy maintenance
- Coupling device is weather resistant and fully protected against corrosion
Applications
- Optimum impedance matching of PLC equipment to power line
- Electrical and galvanic separation between a high voltage power line and PLC parts and maintenance personnel
- Tuning to the desired frequency range with minimum composite loss and maximum return loss
- Insertion and extracting of PLC signals from high voltage power line
