Transformer: 7 Critical Things Every Buyer Must Know Before Choosing One When a transformer fails, the cost is rarely limited to the equipment itself. I have seen buyers lose production uptime, trigger compliance issues, and face expensive rework because they selected a unit based on price or plat...

Yes, we test the products before shipping and provide a factory test report along with the goods. An electronic version of the test report can also be provided.

The rated voltage is 10kV, and the maximum operating voltage is 12kV.

Reliable interlocking devices are selected, and their functionality is tested regularly during inspections. To prevent small animals from entering, cable entry and exit holes are sealed, rodent repellents are installed inside the cabinet, and the environment is kept clean.

Hot melt adhesive on the inner wall firmly bonds the cables together, providing a sealed protection.

The S9 series transformers are mainly suitable for markets with low energy efficiency. The loss index of the S9 does not meet the current energy efficiency requirements, and its long-term operation has high energy consumption. The total cost of electricity over its entire life cycle is much higher t...
