Application Of Pre-insulated Bushings In Inverters

pre insulated sleeve plays a crucial role in the wiring between the DC input and AC output terminals of the inverter. During the connection of photovoltaic modules to the inverter's DC terminals, the wiring passes through pre insulated junction sleeve before being inserted into the terminal block and secured with appropriate crimping tools, thus forming a complete wiring structure. This process is clearly specified in the installation guidelines for a certain model of three-phase string inverter.

On the AC output side, the wire passes through insulated joint sleeve before entering the AC wiring cavity. Bolts and sealing sleeves are used for fixing, ensuring good contact between the conductor and the terminal face.
