Solid Pole For vacuum circuit breaker EEP3-12-16001250-315


solid pole with epoxy resin,is made by casting vacuum interrupters,main circuit conduct and mounting parts with epoxy into an integral part.

  • Product Description

solid pole for vacuum circuit breaker EEP3-12-1600/1250-31.5

Model No: EEP3-12-1600/1250-31.5
solid pole has the following advantages
1.the traditional packaged very column, compared to solid pole column part number a large number of reducing, conductor lap surface by six group reduced to 3 groups, connecting bolt by eight reduced to 1 ~ 3, (see chart 7) simple structure greatly improved the reliability of the circuit breaker
2.Due to the vacuum arc extinguish chamber was embedded into solid material, so don’t need to do any further processing, solid seal pole column can achieve a high dielectric strength; Vacuum arcing chamber was embedded into solid materials, extremely column external environment on vacuum arcing chamber’s influence was reduced to the least.

Information for solid pole

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 solid pole,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 insulations of miniature chambers in air condition fail to fulfill the requests of specifications,solid pole are therefore introduced and now become one of the most applicable ways in the field of medium voltage breakers either at home or abroad.
