isPermaLink="false">http://www.csanyigroup.com/?p=3381</guid> <description><![CDATA[Sulfur Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgears employed by the power industry. Applications for SF6 include gas insulated transmission lines and&#8217;gas insulated power distributions. The combined electrical, physical, chemical and thermal properties offer many advantages when [...]]]></description> <wfw:commentRss>http://www.csanyigroup.com/maintenance-of-sf6-gas-circuit-breakers/feed</wfw:commentRss> <slash:comments>4</slash:comments> </item> <item><title>Maintenance Of High Voltage Circuit Breakers</title><link>http://www.csanyigroup.com/maintenance-of-high-voltage-circuit-breakers</link> <comments>http://www.csanyigroup.com/maintenance-of-high-voltage-circuit-breakers#comments</comments> <pubDate>Sat, 06 Mar 2010 13:17:03 +0000</pubDate> <dc:creator>ecsanyi</dc:creator> <category><![CDATA[High Voltage]]></category> <category><![CDATA[Technical Articles]]></category> <category><![CDATA[circuit breaker]]></category> <category><![CDATA[contact resistance]]></category> <category><![CDATA[current]]></category> <category><![CDATA[defect]]></category> <category><![CDATA[erection]]></category> <category><![CDATA[inspection]]></category> <category><![CDATA[interruption]]></category> <category><![CDATA[maintenance]]></category> <category><![CDATA[mechanism]]></category> <category><![CDATA[oil dielectric]]></category> <category><![CDATA[oil pressure]]></category> <category><![CDATA[operating]]></category> <category><![CDATA[pcb]]></category> <category><![CDATA[spring]]></category> <category><![CDATA[trip]]></category> <guid
