                                          ForESP Porcelain Shafs

                                                  (72~120kV, ≤250°C or ≤350°C,≥1kN·m)

Porcelain Shafts areused as the driver and insulation of the dust removing rappingdevice on corona electrode side of the electrostaticprecipitator(short as esp). 
The insulator consistsof porcelain body and two end fittings assembled together withthermo-resistant cement, with rolled or sanded connecting surface,with thermo-resistant cushion and resilient coating betweenporcelain body and end fittings for preventing from loosing andtorsion and ensuring mechanical strength. 
The porcelain bodysurface is covered with brown or white glaze while the surface ofmetal fittings with anti-corrosionpainting. 
The shaftinsulator conforms to the stipulations ofGB/T772-2005Technical specifications of high-voltage porcelaininsulators. They can be used at surrounding temperature up to250ºC,with working voltage classes from 72 kV to 120 kV, and torsionfailing load not less than 1000 N.M. 

Pls see below tablefor spec, customer design is alsoavailable.
