Wall bushing insulator for ESP

                                            Wall Bushing /Porcelain Sleeve,IEC Standard

                                                                        (72~120kV, ≤250°C or ≤350°C)

Wall Bushing /Porcelain Sleeve  is used between the transformer rectifier and the discharge electrode suspension of an ESP for leading high voltage into the electric filed, functioning as insulating and supporting of the bus rod. By its own structure it is divided into two types: pure ceramic insulator and combined insulator.

A combined insulator consists of the ceramic body and metal fittings which are cemented together with binder that can withstand high temperature. The cementing faces on a ceramic insulator body are knurling or sanding treated, and a high temperature withstanding elastic layer is interposed between the ceramic body end and metal fittings, and a buffer is also applied between them to prevent from loosening.

No metal fittings for pure ceramic insulator type.

The insulator is glazed white or brown on the ceramic part surface, and the metal fittings are applied with anti-rusting paint for the combined insulator type.

The XHDC porcelain sleeve conforms to the Chinese standards of GB/T772-2005 ‘Technical specifications for high-voltage insulator’ and JB/T6746.(1-4)-1993 ‘ceramic insulator used in electrostatic precipitator’, and the IEC series standard is also followed.

Its operating voltage ranging from 72kV to 120kV.
