Zibo electric porcelain factory: six characteristics of post insulator

           Zibo porcelain factory is a professional manufacturer of pillar insulator, with many years of production experience, has been in the industry leading position today with the view of Zibo porcelain factory pillar insulator have which features:

          1, insulator low temperature mechanical performance is good

In order to test the low temperature mechanical properties of the products, the changes of the outdoor winter temperature in the water section of the Songliao water conservancy commission were simulated, and the freezing test of the ZSW1-110/4 insulator was carried out. After several temperature cycles, the test is done at low temperature. The test results show that the flexural failure strength of the insulator at -40 C is no significant change compared with that at room temperature.

          2, high mechanical strength of insulators, small dispersion, safe and reliable operation

          3, radio interference is low

550kV rated voltage of the insulator, at 1.1 times the maximum operating phase voltage, the radio interference is not more than 500 mu V, sunny night without visible corona, visible corona voltage up to 450kV.

          4, the earthquake resistance level is high

Rated voltage 252kV, 550kV insulator, in the Beijing water conservancy and Hydropower Research Institute of the earthquake intensity of 9 anti seismic performance test, the results are in good condition.

          5, good resistance to pollution

The anti fouling performance of insulators is mainly determined by the structure of the product and the shape of the umbrella skirt. A lot of work has been done in this area. Through the design optimization, artificial pollution test and natural pollution test, finally determine the size of the umbrella and the umbrella under the umbrella of the umbrella skirt. Developed by the umbrella skirt is rated voltage is 126kV, 252kV bending failure load of not less than 12 kV, and the specific creepage distance of 25mm/kV insulator, in 0.12mg/ cm 2 equivalent salt density, can tolerate long-term maximum operating voltage, namely insulator III climb electrical distance, tolerance class IV ESDD of filth. Rated voltage of 550kV for the specific creepage distance of 25mm/kV insulator in 0.06mg/ 2 cm ESDD under long-term operation. Insulator pollution level in the lead in the country, it is resistant to the equivalent salt density higher than the same distance, the same size of the umbrella skirt similar products 1/3. The northeast electric power test and Research Institute of insulation of artificial pollution withstand voltage test results show that the creepage distance 31mm/kV insulator withstand the highest value of salt density for 0.25mg/ cm 2.

          6, post insulators meet or exceed the national and international standards

Post insulators are in line with GB8287.1 the high-voltage pillar porcelain insulator technical conditions "and GB12744. The dirt proof outdoor bar shaped pillar porcelain insulator, the provisions of, is also in line with the provisions of the international standard IEC168 the nominal voltage above 1000 Volts system users and outdoor ceramic or glass insulator test" and IEC publication 815 the insulator under polluted conditions selection guide ".
