Brand Name: TSTY
Model Number: ZGS(Pad Mounted Transformer)
ZGS combined transformer(Pad Mounted Transformer), the volume is smaller, more suitable for use in a small area, the main structure is the high pressure side with a plug-in fuse, low pressure according to customer demand there are several lines. This makes the price of the United States will be a little cheaper than the box. We can customize the design according to the customer's site situation.

Small size: The transformer body, high-voltage load switch, fuse and other components are placed together in the compartment, which greatly reduces the size of the components, makes the structure more compact, occupies a small area, is easy to place, and is easy to coordinate with the environment such as the community.
Easy installation: The overall structural design makes the installation process flexible and convenient. It can be customized and configured according to different power systems and needs, and can be quickly installed and put into use.
Low cost: It can shorten the length of low-voltage cables, reduce line losses, and reduce the cost of power supply equipment.

Large-scale manufacturing: annual output of 30000 box transformers;
Customized needs: provide "one-to-one" service from demand analysis, drawing design to factory testing, and urgent project cycles can be negotiated;
High production efficiency: Robotic intelligent manufacturing: full-process automated assembly, welding, testing, production efficiency increased by 60%, product consistency reached 99.8%.
