LMZBJ-10 high/medium-voltage wall bushing adopts a bushing-type product structure, which can easily pass through the screen or wall to achieve current measurement and protection functions. This design not only improves the flexibility of installation, but also enhances the protection performance of the equipment, and can effectively protect the cables/busbars passing through the wall.
Characteristic of structure
This type of transformer consists mainly of epoxy resin, usingquality magnetic core. The transformer doen't take a windingitself, the secondary winding completely casting in epoxy resinsexcellent insulation performance and moistureproof ability, and thesurface is easy to clean. A symbol for the busbar into the line, P1A secondary winding (0.5 or 10P)terminal for 1S1, 1S2 symbolthe second second B Winding 10P(level) for 2S1, 2S2 terminal.Transformer is reduced polarity wiring. The protection shell is in theattachment position. And the electric screen is inside the busbarhole, with equipotential line. The equipotential line will connect thebusbar when installation. The casting body has four installationholes.
