Diameter 500mm Hollow Core Insulators Working Temperature 0℃~400℃
1) the bushing use high aluminum porcelain C130 , the Max. insulator ID we can produce is 500mm , at the same time ,
we must guarantee the insulator profile section is a circle , the
roundess must be in torcelance.
2) The hollow insulator specially used for dust percipitators as a
insulation parts, insulator will working in a souranding
temperature up to 400℃ . which common porcelain can't withstand. So when we make
insulator component design , the Al2O3 percentage must be above 60%
In this way , insulator firing temperature must be over 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 .
All insulators to are well tested before shipment . the tests items are:
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
only the test results are positve, we can start insulator cleaning
and packing ,and following shipments.
we offer 2 years quality guarantee after shipment .
