Dalian No.1 Current Transformers for GIS
Dalian No.1 current transformers for gas insulated switchgear (GIS): CGIS series in ABS enclosures and LZZBJ9 post-type, vacuum-cast epoxy units with low partial discharge, for 10 kV and 35 kV switchgear.

Product Overview
Dalian No.1 Instrument Transformer was founded in 1972 and researches, makes and sells instrument transformers; the company describes itself as one of the top three in China in this field. Its range covers current and voltage transformers from 0.5 kV to 765 kV.
For gas insulated switchgear (GIS) it offers the CGIS series of window-type units in ABS enclosures (the busbar or cable passes through the centre opening), round and oval, and the LZZBJ9 series of single-phase post-type units.
LZZBJ9 units are vacuum-cast in epoxy resin with low partial discharge and are mainly installed in gas insulated switchgear. The current transformers serve metering and relay protection.
