This comprehensive article delves deep into these offerings, exploring technical specifications, design advantages, real-world applications, and the added value of choosing Leistung Energie.
High Voltage Products – Driving the Future of Power Systems
High voltage products are essential for managing and controlling energy flow in modern electrical grids. Whether for substations, industrial complexes, or critical infrastructure, reliable switchgear ensures safety, efficiency, and grid resilience.
What Are High Voltage Products?
High voltage products encompass equipment designed to handle electrical loads typically above 72.5kV. They include switchgear, circuit breakers, disconnectors, current transformers, and surge arresters. By integrating such components, utilities can isolate faults, control load flow, and maintain grid stability.
High voltage systems are foundational to the global energy infrastructure, enabling energy to be transmitted over vast distances with minimal loss. The evolution of such systems reflects technological progress and the shift toward cleaner, smarter grids.
Why Choose GIS Over AIS?
Gas Insulated Switchgear (GIS), as opposed to Air Insulated Switchgear (AIS), uses sulfur hexafluoride (SF₆) gas or eco-friendly alternatives for insulation. Compared to AIS, GIS delivers:
Dramatically reduced footprint—about 10% of AIS substations
Enhanced environmental resilience and minimal maintenance
Modular design for easy expansion and on-site fitting
The advantages of GIS extend beyond space savings. Their robust insulation properties make them suitable for use in harsh climates, such as deserts, high altitudes, and urban centers prone to pollution. Additionally, GIS is safer due to its encapsulated design, reducing risks associated with human interaction and environmental factors.
GFM Switchgear 145kV – Compact Performance, Maximum Reliability
Overview of GFM Switchgear
The GFM 145kV is an SF₆ gas-insulated, metal-clad switchgear engineered for dependable medium-to-high voltage applications across multiple industries, including utilities, petrochemicals, data centers, airports, and subways.
This switchgear stands out due to its scalability and operational efficiency, making it a favored choice for both retrofitting existing systems and establishing new installations. Its design reflects a balance between advanced engineering and practical usability.
Key Technical Features
Operates up to 145kV with 40kA short-circuit and 3150A rated current
Equipped with German-engineered SF₆ interrupters
Enclosures crafted from aluminium alloy to minimize eddy current loss, boost rust resistance, and reduce weight
Factory-tested before shipping—reducing on-site installation time by up to 30%
Structural Advantages & Modular Expandability
GFM is designed for flexibility—each phase housed in its own compartment, with expansion couplings for rapid system upgrades or maintenance. This modularity means interruptions are minimized and future expansion is seamless.
The modularity also extends to its diagnostics and monitoring systems. Advanced sensors integrated into the switchgear allow operators to identify potential faults early, ensuring continued reliability and performance.
Compact Footprint & Environmental Tolerance
Boasting a 90% reduction in space requirements vs AIS, GFM is ideal for urban projects or sites with limited real estate. The SF₆ insulation protects internal components from external conditions, reducing contamination risk.
Maintenance Efficiency & Lifecycle Cost
Low-maintenance needs, mainly periodic SF₆ monitoring and mechanical inspections, lead to a reduced total cost of ownership. The durable aluminium build further extends operational lifespan, making GFM an economically sound investment.
Long-term cost benefits include reduced operational disruptions, energy efficiency gains, and compliance with stringent environmental regulations.
ZF 16‑363 GIS – High Capacity, Broad Compatibility
Leveraging 50+ Years of Technological Expertise
