VTZ Series Vacuum Circuit Breakers are key products in medium voltage power systems and are suitable for ensuring electrical safety in various industrial sectors. In this article, we will take a closer look at what defines the VTZ Series and what distinguishes it in terms of classifications, functionalities and benefits for individual needs. Next, we will talk about why this series is a great option for companies that are look after energy efficient and maintenance-free solutions.
What Is the VTZ Series?
We have developed the VTZ brand of vacuum circuit breakers, designed for medium voltage systems ranging from 12kV to 40.5kV. These breakers are essential for protecting and controlling electrical circuits in industrial plants, substations, and other applications where efficient electrical management is critical.
This series can be divided into three voltage levels:
VTZ-12: These can replace international models with voltage levels of 11kV, 12kV, 13.8kV, or 17.5kV.
VTZ-24: These are suitable replacements for international 24kV and 25.8kV circuit breakers.
VTZ-40.5: These can replace 33kV, 36kV, and 40. 5kV products used internationally.
This wide range allows the series to cover many voltage levels, making it suitable for use in a variety of situations.
Types of VTZ Series Circuit Breakers
Our vacuum circuit breakers come in two main types based on how they are installed:
Fixed-Type Circuit Breakers: These are installed in a cabinet or on a special bracket. These breakers are typically used in combination with isolating switching, grounding switching, etc., and require equipped interlocks devices to ensure safe operation.
Withdrawable (Handcart-Type) Circuit Breakers: These are equipped with a propulsion device that moves and separates the circuit breaker body and the high voltage part in the cabinet, and also has a fixed and moved contact. These breakers can be completely moved out for maintenance, ensuring safety and reliability.
Why Choose Our VTZ brand?
Our VTZ products offer several advantages that make them a popular choice for medium voltage systems.
1. Modular Design for Easy Maintenance
All VTZ Series products have a modular design, which means that the mechanism can be disassembled independently. This design makes the breakers more compact and easy to maintain, ensuring space efficiency and low maintenance costs. Key parts of the breaker are molded as a single unit, which ensures high consistency and reliability. The modular mechanism can also include an energy storage handle that would enhances user convenience and operational efficiency.
2. Long Lifespan and Low Maintenance Costs
A major advantage of having the VTZ is the fact that it is relatively long-lasting and requires little or no maintenance. While older vacuum circuit breakers such as the VS1 needed maintenance after 2,000 operations, the VTZ can last for at least 10,000 operations without any maintenance. This significant improvement reduces maintenance costs, providing users with long-term reliability and cost savings.
3. Wide Range of Applications
The VTZ Series Vacuum Circuit Breakers are designed to meet various electrical requirements. They can support rated currents from 630A to 6,300A and breaking currents from 20kA to 80kA, making them suitable for many types of medium voltage applications. These breakers can also work in temperatures from -40°C to 40°C, which makes them reliable even in extreme weather conditions. Additionally, they can be installed in areas of up to 4,500 meters and this make them suitable for different locations. In addition, the products can be customized for special applications, which ensures adaptability and performance in unique situations.
4. High Adaptability
The modular mechanism of our products ensures high compatibility with various retrofit applications. This feature makes it possible to upgrade old switches and improve the performance and reliability of existing electrical systems.
Where Is the VTZ Series Used?
VTZ Series Vacuum Circuit Breakers are used in numerous industries and applications, such as:
Power Distribution Systems: These circuit breakers help ensure a stable and safe power supply in both urban and rural areas.
Industrial Enterprise: High voltage equipment in factories, steel mills and mining operations require some serious circuit breakers that should keep the electrical system running.
Substations: The series provides control of the power flow and, consequently isolates areas to function or assist in maintenance work on medium voltage substations.
Infrastructure and Utilities: These circuit breakers are applied in different infrastructural applications that include the renewable energy systems such as the wind farms and the normal power plants.
Conclusion
Basically, the VTZ Series is a safe and reliable choice for your medium voltage systems. It is also a great solution for many industries because of their long life, low maintenance need and countless possible applications. Thanks to their wide range of applications in new systems and the easy retrofitting of existing applications, these products can be installed very flexible. When you choose our VTZ Series Vacuum Circuit Breakers, you choose a cost-effective, efficient and durable solution for your electrical needs.
