jdqx-110/220 sf6 voltage transformer

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.
