jdqx-110
jdqx-220
main features of the product:
1. it has two kinds of structures: porcelain sleeve and composite hollow insulator, which can meet the needs of different users;
2. the whole system is capacitive and can effectively avoid ferroresonance;
3. large capacity, high accuracy and good insulation performance.
