ZBP-1 – MV PLC Equipment

MV PLC communications – Distribution Line Carrier for urban environment

Main applications: Data transmission in mid-distance levels (urban environment) + Connectivity between Distribution Transformer Centers (DTC).

The main purpose of the ZBP-1 is data transport for services in Medium Voltage Secondary Substations to a Primary Substation. The ZBP-1 is a good option for transmitting data at high speed between Distribution Transformer Centers, using the existing infrastructure (medium-voltage power lines).

The ZBP-1 allows transmission of data at high speed over short medium-voltage power lines. To achieve this goal, the system makes use of an Orthogonal frequency-division multiplexing (OFDM) modulation.

The channel is constantly evaluated in such a way that the carriers that are affected by noise or interferences can automatically reduce its base modulation or even not be used at all.

The ZBP-1 is made up of a mechanical chassis, which houses the power supply and digital  modem unit.
