White / Brown / Grey Color Hollow Core Insulators For Dust
1) the bushing use high aluminum porcelain C130 , which guarantee the bushing have perfect mechanical character .
2) This kind of hollow insulator specially used for dust
percipitators , because of specially working temperature
requirement , so the insulator must withstand Min.400℃ . normal porcelain can't reach this level . When we make
insulator component design , the Al2O3 percentage must be above 60%
so it leads to firing temperature must be more than 1300℃ ,the
related production cost will increase much also .
3) the applicable standard is IEC standard .
specially used for dust percipitators as a mechanical support
parts and insulation parts also .
we tested each unit of hollow insulators to be sure all bushings are qualified . the tests including :
1) routine visual inspection , routine water pressure test and
electrical flashover test
2) sample test , for example dimensional check , porosity test etc.
mechanical bending load test , water burst test etc. on every lot
in this case the user can use our product safely .
we offer 2 years quality guarantee after shipment .
The porcelain glaze are smooth and shinning , it is easy for
