Main performance of JLSZ �� series outdoor dry-type combination transformer

1. Rated voltage: divided into 3 × 6kV, 3 × 10kV, 3 × 35kV
2. Rated transformation ratio: Voltage ratio: 6000/100V, 10000/100V, 35000/100V.
Current ratio: 1-1000/5A, and divided into single transformation ratio and dual transformation ratio.
The primary wiring P1 and P2 of the dual ratio measuring box have a high current ratio.
P1 and P3 are small current ratios.
3. Rated capacity: PT components are divided into three types: 15, 25, and 50VA.
CT components are divided into three types: 10, 25, and 30VA.
4. Accuracy levels: 0.5, 0.2, 0.5S, 0.2S.
