Product Overview
XGN17-40.5 is a mature indoor box-type fixed AC metal-enclosed high voltage switchgear designed for 40.5kV (35kV), 50/60Hz three-phase AC power systems. As a professional fixed-type high voltage power distribution device, it is widely used in urban power substations, thermal power plants, new energy power stations, mining enterprises, chemical industries and large industrial parks. It undertakes core functions of power receiving, distribution, circuit control, fault protection and electrical parameter measurement for medium and high voltage power grids.
Adopting an integral welded steel plate box-type structure, the XGN17-40.5 switchgear abandons the withdrawable handcart design and features ultra-high structural rigidity and mechanical stability. The whole cabinet has strong vibration resistance, deformation resistance and environmental adaptability, capable of long-term stable operation in humid, dusty and high-altitude indoor environments. Equipped with high-performance vacuum circuit breakers and standardized mechanical interlock systems, the equipment realizes safe and reliable switching operation, meeting frequent operational demands of industrial power systems.
Core Advantages
1. Superior Structural Stability：Integrated welded box-type framework ensures high overall strength, no deformation after long-term operation, excellent shock and vibration resistance, far more stable than assembled switchgear in harsh working conditions.
2. Complete Safety Protection System：Built-in standard five anti-misoperation mechanical interlock devices, effectively preventing mis-closing, mis-opening, live-line grounding and other hazardous operations, fully protecting equipment and on-site operating personnel safety.
3. High Cost Performance & Low Operation Cost：Mature and simple fixed structure with fewer vulnerable parts, lower daily maintenance and replacement costs. Stable operation without frequent overhaul, greatly reducing long-term operational investment for power projects.
4. Strong Environmental Adaptability：Optimized cabinet sealing and structural design, adaptable to high altitude, high humidity and dusty indoor environments. Supports diversified module configuration of protection, measurement and communication to meet customized project construction demands.
