Bushing used on distribution transformer(IEC standard)

Product Description

Product Description
The series of transformer bushing used for power transformer in this samples have the following advantage:low level of partial discharge excellent sealing effect;beautiful appearance and so on.According to the characterietics of the power transformers,we improve the design concept and manufacturing process in order,to make the installation more convenient and reduce the cost.

Technical parameters

10~35kV bushing sealing structure description

  1. Fig18,the sealing position is cylindrical surface.
  2. Using O-ring,sealing diameter is less than the cylindical,form a pre-stress.
  3. Two installation methods:a)Fig20,installed directly with tank of transformer;b)Fig21,installed through the transition flange with tank of transition flange with tank of transformer.(The transition flange material is stainless steel or non-magnetic steel)                                                                                                                                                      
  4. Fig18,bushing run some years later,the O-ring can be tightened up again,ensure a reliable seal.            

Advantage of the bushing:

  1. The sealing poistion is cylindrical surface,can't easily be damaged,flexural strength achieve 4000N,can be installed level,sealing structure is simple,safe and reliable;
  2. Simplify the processing of the tank,reduce costs of the transition;
  3. Bushings with 20kV and above voltage level,design gas plug to ensure reliable electrical performance;
  4. Head structure using patented technology,sealing performance is reliable;
  5. Porcelain insulation is designed to be without breakthrough,even if the gap of tank exists gas or insulation is not handled properly inside of bushings.
