1. POWER LINE CARRIER COUPLING DEVICE
PUNCOM offers PCD-1400 , a modular coupling device , consisting of LMU and protective devices to couple the PLCC terminals with the high voltage transmission line. It is designed to provide phase to earth and phase to phase coupling. The coupling device is purely passive and acts as an interface between the HT power line and PLCC terminal. It provides efficient transmission of carrier frequency signals and protection against high voltage power leakage and transient voltages. The coupling device is designed to provide high level of safety and protection of the Power Line Carrier Equipment. It provides optimum impedance matching , frequency separation and safe isolation. It is designed to provide fast and easy installation. PUNCOM make PCD-1400 complies to IEC and IS 8997 specifications
