Description of model:

       Epoxy embedded poles, or called vacuum interrupters with epoxy resin, is made by casting vacuum interrupters, main circuit conduct and mounting parts with epoxy into an integral part. The vacuum interrupters, however, should be enveloped well with a slight fold of silicon rubber jacket before that process.

       From the development of insulations on breakers, it can be divided into three generations: air, composite and solid insulation and so-called solid insulation means epoxy embedded poles, 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. The embedded poles of Xuguang are all made by Automatic Pressure Gelation process(APG process) and have many features such as integrated mold production, free maintenance, compact, stable and reliable dielectric strength and etc.. When the external insulations of miniature chambers in air condition fail to fulfill the requests of specifications, embedded poles are therefore introduced and now become one of the most applicable ways in the field of medium voltage breakers either at home or abroad.

      Since the first embedded pole was given birth in 1997, Xuguang has indulged in research of the technology over ten years and now has achieved great advancements. Annually our production and sales volume reach to 10,000 sets, and some of them are exported to several countries such as Poland, Russia and Turkey.

      Main technical data is: rated voltage ranging from 12KV to40.5KV; rated current ranging from 630A to 4000A; rated short time breaking current ranging from 16KA to 50KA. Our vacuum interrupters are designed to operate under GB1984-2003 or E2 level of IEC62271-100.
