ODM ZGS11-H(Z) Combined Transformer Manufacturers, Company

ZGS11 combined transformers are high-tech products independently developed by our company based on the technology of American padmounted transformers, also known as American-style box-type substations. They feature strong integration, reliable power supply, small size, light weight and low noise, with looped network type and terminal type cable outgoing lines. Application of this product enables the 10kV power grid to extend deep into load centers, reducing line loss and improving power supply reliability, making it suitable for urban grid renovation.

Product Features

★
Compared with Type "9" transformers, this product reduces no-load loss by 30.12% and average annual operating cost by 20.03%, with low noise, making it an environmentally friendly product.
★
The transformer body, high-voltage load switch (or high-voltage load transfer switch), fuses, off-circuit tap-changer, etc., are all placed in a fully sealed oil tank, improving space utilization. Its volume is only about 1/3 of that of combined substations (also known as European-style substations) of the same voltage class and capacity, and the weight is also greatly reduced.
★
High-voltage and low-voltage compartments are isolated and interlocked: the high-voltage compartment door can only be opened after the low-voltage compartment door is opened, and high-voltage terminals are fully insulated, ensuring high safety.
★
It adopts a full-range protection method combining two-stage fuses (backup current-limiting fuses and plug-in fuses), which is safe and reliable, flexible in operation and convenient for fuse replacement.
★
The oil tank is of fully sealed structure, isolating the oil inside from the outside, with no leakage and maintenance-free.

Frequently Asked Questions (FAQ)

Q What does the designation ZGS11 stand for?
Z stands for Combined Transformer, G denotes Common Tank Type, S signifies Three-Phase, and 11 represents the Performance Level Code.
Q How does the energy efficiency of ZGS11 compare to older Type 9 models?
The ZGS11 reduces no-load loss by 30.12% and average annual operating cost by 20.03%, operating with low noise and high environmental efficiency.
Q How compact is the common tank design compared to European-style substations?
Because the core, switches, fuses, and tap-changer are integrated in a single sealed tank, its physical volume is reduced to approximately 1/3 of traditional European-style substations of the same class.
Q What safety interlocking mechanisms are implemented in the compartments?
The high-voltage and low-voltage compartments are isolated and interlocked; the high-voltage door can only be unlocked and opened after the low-voltage door is opened, and HV terminals are fully insulated.
Q What protection system is utilized against electrical faults?
It employs a dual protection setup combining backup current-limiting fuses and plug-in fuses to provide full-range protection with convenient replacement.
Q What high-voltage wiring configurations are available for this series?
The unit is available in either a Looped Network Type (indicated by H) or a Terminal Type (indicated by Z) based on network requirements.
