Abstract: Introduction was made to the current situation of 10 kV ring main unit. This paper expounded the structure characteristic of solid insulation, SF6 gas insulation and environmental protection gas insulation ring main unit, gave their structure chart, compared several relative merits of three kinds of ring main units, and analyzed the technical characteristic and market application. The ring main unit has the characteristics of oil-free and miniaturization, with simple structure, reliable and safe operation, less maintenance and low operation cost, superior to the
traditional switchgear.
Key words: solid insulation; gas insulation; environmental protection gas insulation; technical characteristic
