ChinaKey features
S11 low-loss core made of grain-oriented cold-rolled silicon steel sheets with full-oblique joints reduces no-load loss and noise.
Robust double-winding concentric coils ensure high mechanical strength against short-circuit electrodynamic stresses.
Tank-cover-mounted off-circuit tap changer offers safe non-excitation voltage regulation within a +/-5% or +/-2x2.5% range.
Equipped with complete safety devices: Buchholz relay, pressure relief valve, oil conservator, and dehydrating breather.

Product Q&A
Q:Can the low-voltage side phase distance be customized?
A:
Yes. We specialize in an order-driven manufacturing model based directly on client-supplied technical specifications and circuit diagrams. While standard phase spacing parameters are available, the physical phase distance and layout configurations can be flexibly customized or engineered to align precisely with your specific switchgear connection requirements.
Q:What standard safety and protection devices are included with the transformer?
A:
Every unit is comprehensively equipped with automated station protection devices, including a highly sensitive Buchholz relay for internal gas fault monitoring, a rapid pressure relief valve for sudden overpressure venting, a durable oil conservator with a precise oil level gauge, and a specialized dehydrating breather with an integrated oil seal to isolate ambient moisture.
Q:What are the requirements for changing the voltage tap settings?
A:
The transformer is designed with an off-circuit tap changer mounted directly on the tank cover, regulating voltage within a +/-5% or +/-2x2.5% range. To change the voltage tap, the power system must be completely de-energized beforehand. Tap shifting must strictly be performed under non-excitation conditions to ensure absolute operational and insulation safety.
