LMZJ1 Epoxy Resin Current Transformer
Rated voltage 0.5 / 0.66 kV
Type Indoor ring type, single phase
A post type instrument transformer cast in epoxy resin for 36 kV indoor switchgear. The type code itself reads the specification: L current transformer, Z post type, Z cast epoxy resin, B protective, 9 design sequence, 36 rated voltage.
Medium voltage current transformer LZZBJ9-36/250(II). The type designation decodes as: L current transformer, Z post type, Z cast epoxy resin, B protective, 9 design sequence, 36 rated voltage, 250(II) structure code. Net weight 80 kg.
The wider family covers LZZBJ9 in 12 kV, 24 kV and 36 kV indoor single phase epoxy resin type, alongside outdoor pole mounted SF6 manual load break equipment in the same catalogue.

The published family covers 12 kV, 24 kV and 36 kV indoor single phase epoxy resin post type current transformers.
It is the structure code, which identifies the mechanical configuration of the frame. Quote it when ordering so the replacement matches the existing unit.
The catalogue also lists LZZB7-35Q and LZZW-35 medium voltage current transformers. Ask an engineer for the equivalent to your existing unit.
