It is built to operate reliably under extreme temperatures, heavy pollution, and high humidity levels, making it suitable for a wide range of outdoor applications.
Offering versatile operational modes, the device is available in manual, motorized, or remote-controlled versions. This flexibility allows it to adapt to different automation requirements and fit seamlessly into various grid configurations, enhancing convenience and control.
The design emphasizes low maintenance through a simplified mechanical structure that incorporates self-lubricating bearings. This results in reduced lifecycle costs and less frequent servicing, ensuring long-term efficiency and reliability.
Technical Parameters:
The rated voltage for this equipment ranges from 12kV up to 550kV, with options available for customization to meet specific requirements. This allows for flexibility in different electrical applications.
The rated current capacity varies between 630A and 4000A, ensuring suitability for a wide variety of power systems and load demands. This broad current range supports both medium and high power installations.
It can withstand short-circuit currents between 20kA and 50kA for a duration of three seconds. This high short-time withstand current rating provides enhanced safety and resilience during fault conditions.
Designed in accordance with standard IEC and IEEE guidelines, the insulation level includes an increased creepage distance. This feature specifically improves performance and reliability in polluted environments where contamination could affect insulation integrity.
The operating mechanism can be selected from multiple options, including a manual lever, electric motor drive, or pneumatic actuator. This versatility allows users to choose the most convenient or suitable actuation method based on their installation needs.
The device is rated with an environmental protection level of IP54 or IP55, making it resistant to dust and water ingress. It is capable of functioning efficiently at altitudes up to 4000 meters and in extreme temperature conditions ranging from -40°C to +55°C.
Applications:
These devices are extensively utilized in utility substations, primarily for busbar sectionalizing and the isolation of transformers. Their application ensures efficient management and safety of electrical distribution within these substations.
Along overhead transmission lines, they play a vital role in circuit segmentation. By enabling sectionalizing of the power lines, they help maintain system stability and facilitate maintenance operations without disrupting the entire grid.
Moreover, they constitute an essential part of renewable energy projects, including solar farms and wind parks. Their presence enhances grid connection safety, ensuring that energy generated from renewable sources is integrated reliably into the electrical network.
In addition to these applications, these switches are critical for large-scale industrial facilities and railway traction systems that demand dependable high-voltage switching solutions. Their robustness and reliability support the continuous operation of such high-demand environments.
