110kv-550kv Aluminium Alloy Shielding Rings/ Corona Rings for Insulators

Brief Introduction:
The design of the corona ring is done by accurate digital assimilation in order to reduce and to balance the electrical field around and on the insulator’s sheds. The corona ring is made of aluminum which is resistant against harsh weather conditions; it is polished for the reasons of reducing Corona and partial discharge. The utilized bolts and arms in Corona ring are all made of stainless steel in order to be anti-corrosion.

The special design of the Corona ring makes impossible any inaccuracy in its installation.

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.
