Glass Insulator Assembling:
Workshop Overview:
In order to control the quality and improve producing efficiency, we have bought the modern producing line instead of handwork. Firstly, it can improve the producing capability. What's more, can reduce the employee's workload.
Strict Quality Control:
We have the complete quality control system. The control is from raw material, producing process to the finished product. And the quality control include the chemical composition, mechanical load, metallographic analysis, detection of defects, dimension.
Type Test--glass insulator:
1. Dry lightning impulse withstand voltage test
2. Wet power frequency withstand voltage test
3. Mechanical load test
4. Puncture withstand test
5. Verification of dimensions
