No-Load Tap Changer Design: WST II model designed for off-circuit operation to ensure safety and prevent arcing.
Central Tapping Configuration: Type II design with six taps per phase connected to the high-voltage winding mid-point.
Oil Immersion Cooling: Mechanism immersed in insulating transformer oil for dielectric strength and heat dissipation.
Medium Voltage Compatibility: Specifically designed for three-phase bar-type switching in networks up to 10 kV.
Robust Compact Structure: Ideal for distribution transformers ensuring stable voltage levels with strict safety protocols.
Mandatory DC Resistance Testing: Post-adjustment testing required to confirm contact integrity and installation accuracy.
Global Market Presence: Exporting to North America, Europe, Asia, Africa, and Oceania since 2002.

Product Q&A
Q:What is the difference between this tap-changer and an OLTC?
A:
This is a no-load (off-circuit) tap-changer that must operate only when the transformer is de-energized, unlike OLTCs which switch under full load.
Q:What is the maximum voltage for this model?
A:
The WST II is designed for medium voltage networks up to 10 kV.
Q:How is the mechanism cooled and insulated?
A:
The entire mechanism is immersed in insulating transformer oil to ensure dielectric strength and heat dissipation.
Q:What safety protocols are required during operation?
A:
Operation under load is strictly prohibited to prevent arcing and equipment damage.
Q:What is the average lead time for delivery?
A:
Peak season lead time is one month, while off-season lead time is within 15 workdays.
