POLYMER INSULATOR IN WHICH A CORONA RING IS MOUNTED IN ORDER TO RELIEVE AN ELECTRIC FIELD

摘要

PURPOSE: A polymer insulator in which a corona ring is mounted is provided to facilitate installation by easily combining a protrusion part with a groove.;CONSTITUTION: A corona ring part includes a connection member. The connection member connects a first corona ring and a second corona ring. A pair of support members is respectively combined with one side and the other side of the corona ring part. A protrusion part(170) protrudes from the inner periphery of a first connection ring(200a) and a second connection ring(200b). A groove part(210) inserts the protrusion part.;COPYRIGHT KIPO 2013
