The wall-through bushing is used for support and isolates the place where the corona electrets bus bar gets through the ESP shell. There're two types of them according to the structure: assembled bushing and bare porcelain body.
Produced with the porcelain material C795, the products could withstand more than 500 ºC working temperature even under the high voltage.
The assembled wall-through bushing consists of porcelain body and metal accessories. These two parts are combined by Portland cementing or the thermal-resisting gluing. Elastic pad and buffer layer are used between the porcelain body and metal accessory to prevent loosening. It helps to guarantee the mechanical strengths.
According to the working circumstances, we suggest our customer to choose the different material to ensure the ESP's stable running. Suggestions as following:Â
  Material C130(Alumina>40%) Working temperature:<250ºC;
  Material C610(Alumina>55%) Working temperature:<350ºC;
  Material C795(Alumina>95%) Working temperature:>500ºC;
Other features of our products:
High tension, High duration and High resistivity to the complicated working circumstances.
The rated working voltage: 60kv to 120kv.
Compressing withstand Load ≥ 500kN.
For C130 & C610, Glazed brown RAL 8017 or grey ANSI 70.Â
For C795, Usually unglazed, Polished inside and outside only.
Production and Test according to GB, IEC, IS etc.
