Process control on Composite insulators :

High quality products  are  the firm base for a growing company . We focus on the insulators quality ,and make strictly controlment  from below aspects:  

raw material.jpg

1) Raw material is the critical base of qualified insulators. firstly , we must select high quality raw  material ; both  chemical and physical inspection will be conducted on all type of raw materials (fiber glass rod , silicone rubber, metal fittings etc.  After incoming inspection , the qualified raw material will be marked and stored seperately for futher production .the unqualified material is doomed to be rejected.

2) We have a technical &  inspection center .There are more than 42 experiencend inspectors working for the whole manufacturing process to check hundreds of control points  from raw material、  injection machine, working temperatures, different material storage situations , different material usage  validity period , test, packing etc.  It monitors, records, analyzes and evaluates technological parameters to finalize  process quality analysis reports. After the basic datas collection ,we can easily know the whole process status , and take promptly action on some defect or mistake correction . All those controlment make us sure the final product are very qualified  .

3) During the quality control process ,we must be sure all measuring and testing equipment, which is used in manufacture, control and inspection are valid . so all those equipment must be calibrated  periodically.

4) Another good way to control insulator quality is marking . it can make all process trackable . we mark all the manufacturing process points on product ,from the raw material to packing . you can know clearly know the information that who is the operator in different manufacturing process. if some defect happend , we can easily track reason .  we improve qualified rate continuously through those controlment  , because all stuffs must be responsible for their work .We are strictly comply with test procedure doing related tests , for example, each insulators must be routine tested , sample tests  must be done on each lot against different Standards such as IEC, ANSI, BS etc.

5) We have a researching center , which can design insulators according to customers specfication or requirements.The engineers are also keeping researching the ways to make whole process steable ,  and make our factory improving continuously.

 6) We strictly comply with ISO9001 :2008,and still go forward with quality improving .   Our target is to supply qualified insulator all over the world.

 2) We have a technical &  inspection center .There are more than 42 experiencend inspectors working for the whole manufacturing process to check hundreds of control points  from raw material, ball mill ,insulator shaping,drying,glazing,firing and final product assembly,test, packing etc.   

 It monitors , records, analyzes and evaluates the technological parameters to finalize  process quality analysis reports.    

After the basic datas collection ,we can easily know the whole process status , and take promptly action on some defect or mistake correction . All those controlment make us sure the final product are very qualified  .

4) Another good way to control insulator quality is marking . it can make all process trackable .  we mark all the manufacturing process points on product ,from the sludge to packing .

you can know clearly  the information that who is the operator for shaping & galzing etc.,and also the firing date , lot No. etc.

if some defect happend , we can easily track reason .  we improve qualified rate continuously through those controlment  , because all stuffs must be responsible for their work .

5) For each kiln , some experienced  workers must do prosity test and porcelain profile analysis to be sure the porcelain is fired properly .  

We are strictly comply with test procedure doing related tests , for example, each insulators must be routine tested ,  sample tests  must be done on each lot against different Standards such as IEC, ANSI, BS etc.


6) We have a researching center , which can design insulators according to customers specfication or requirements.  The engineers are also keeping researching the ways to make whole process stable , and make our factory improving continuously.


7) We strictly comply with ISO9001 :2008,and still go forward with quality improving .    Our target is to supply qualified insulators all over the world. 

We, Dalian Hivolt Power System Co.,Ltd.  have a very modern laboratory in our factory, where routine test, sample test and normal type test can be conducted in accordance with IEC, ANSI, BS, AS and other international standards.  Test range including porcelain insulators and composite insulators .The test equipment listed below:
