Electrical Fittings Composite Insulator High Voltage Corona Ring
aluminum alloy grading rings/Corona ring:
For AC/DC polymer composite insulators, it can be high voltage evenly distributed around the object to ensure the potential of every position around the ring consistent.
The purpose of the ring is very extensive, it can be divided into; Arrester corona ring, lightning protection; Corona ring, insulator corona ring, transformer corona ring, corona ring of high voltage test equipment, power transmission line corona ring.
Meanwhile, in a lot of supporting precision measurement of electrical equipment, often used shielding corona ring, or shield ring.
