What is Grading Ring?
Compared to electric porcelain insulator, composite insulator is
featured with high intensity, light weight, high wet-flashover and
flashover voltage, easy operation maintenance, strong ability of
impulse withstand, widely applied to transmission line suspension
string, and has spread application in tension string in recent
years. Surface field distribution and potential distribution for
composite insulator without corona ring is greatly uneven, due to
composite insulator structure characteristics and high resistivity
feature of silicon rubber, surface field density is highest at
mandrel and steel cap joint, distribution voltage is highest at
first umbrella dress near high voltage end. Exorbitant surface
field density not only generate corona discharge, affect
transmission line electromagnetic environment, produce audible
sound pollution, but also cause strong electric erosion, causing
further insulator aging. Corona ring installation is the normal
solution to the problem of uneven potential field density
distribution at insulator high voltage end. Installation of corona
ring helps to transfer maximum field density from insulator surface
to corona ring surface, thus effectively improves electric field
distribution on insulator surface.
Application:

| A: | We are grading rings manufacturing factory in China Mainland. |
| 2.Q: | In case the aluminium grading ring exists problem, how to do after sales service? |
| A: | To be honest, mistakes happen in business. But not all the suppliers have the problem-solving ability. Some of them avoid to take responsibility. Some of them want to solve the problem, but have no ability to pay for the mistake. HighV people will be honest to take responsibility for all of our mistakes. We will provide new grading rings required with free of charge by express. More and more customers choose us because we take care of every business. |
| 3.Q: | What’s the delivery time? |
| A: | Generally speaking, lead time is 15-35 working days after receive the payment. |
| 4.Q: | How does you factory do regarding quality control? |
| A: | HighV people always attach great importance to quality controlling from the very beginning to the very end. We could do the pre-shipment inspection for you. |
| 5.Q: | How about the shielding grading ring surface treatment? |
| A: | Hot Galvanized/Polished Bright. |
| 6.Q: | What's painting of the grading ring? |
| A: | During normal processing, the grading ring is made of the aluminum
and steel. The surface finish does not require the painting. HighV supply painting service according to customers requirement. Such as Color painting, Galvanized etc. Other Tungsten plating, copper plating, etc, are available. |
