Information for solid seal pole column<\/strong>
\nFrom the development of insulation on breakers,it can be divided into three generations:air, composite and solid insulation. And so-called solid insulation means solid seal pole column,which might represent the great advancement of insulation on vacuum breakers.Since the epoxy can be used to replace the insulating and mechanical supports,the breakers therefore become compact and simple and are able to service under humid and dusty conditions.When the external insulation of miniature chambers in air condition fail to fulfill the requests of specifications,solid seal pole column are therefore introduced and now become one of the most applicable ways in the field of medium voltage breakers either at home or abroad.<\/p>\n
