Product Q&A

Q:What is the difference between this switch and an OLTC?

Unlike On-Load Tap-Changers (OLTC) that switch under full load, this WST II is a no-load switch that must only operate when the transformer is de-energized.

Q:Is this switch suitable for operation under load?

No, operation under load is strictly prohibited to prevent arcing and equipment damage; it must only be adjusted when the transformer is off.

Q:What are the available height dimensions?

The switch is available in multiple heights including 70mm, 100mm, 120mm, 130mm, 150mm, 170mm, and 200mm to match different winding requirements.

Q:What is the rated voltage and current?

The rated voltage is 36KV, with rated current options of 30A and 63A.

Q:What is the lead time for delivery?

During peak season, the lead time is one month; during the off-season, it is within 15 workdays.
