TG3-12-110×180 Switchgear Through Wall Bushing – Technical Description The TG3-12-110×180 Switchgear Through Wall Bushing is a critical component designed for high-voltage electrical systems, facilitating safe and efficient power transmission through walls or barriers in switchgear installations. This bushing ensures electrical insulation, mechanical stability, and environmental protection while maintaining reliable performance in demanding industrial and utility applications. Design and Construction The bushing features a robust design with a rated voltage of 12 kV and a current capacity of 110 A, making it suitable for medium-voltage applications. Its dimensions (110×180 mm) are optimized for compatibility with standard switchgear configurations. The core consists of high-quality insulating materials, such as porcelain, epoxy resin, or silicone rubber, chosen for their excellent dielectric strength and resistance to thermal and mechanical stress. The through-wall design incorporates a flanged housing for secure mounting, ensuring a gas-tight or dust-proof seal when installed in panels or enclosures. The internal conductive element (typically copper or aluminum) is precision-engineered to minimize electrical losses and withstand short-circuit currents. Key Features 1. Electrical Insulation: Provides high dielectric strength to prevent flashovers or leakage currents, even in humid or polluted environments. 2. Mechanical Durability: Resists vibrations, impacts, and thermal cycling, ensuring long-term reliability. 3. Environmental Protection: Sealing gaskets or O-rings prevent moisture, dust, or corrosive gases from compromising performance. 4. Easy Installation: Pre-drilled mounting holes and standardized dimensions simplify integration into switchgear systems. 5. Safety Compliance: Meets international standards (e.g., IEC, ANSI) for insulation coordination and fire resistance. Applications - Switchgear Panels: Connects internal and external circuits in substations or industrial power distribution systems. - Transformer Installations: Acts as a feed-through for transformers housed in separate compartments. - Renewable Energy Systems: Used in wind or solar farms where equipment is segregated for safety. Performance Parameters - Rated Voltage: 12 kV - Rated Current: 110 A - Frequency: 50/60 Hz - Creepage Distance: Optimized for pollution resistance (e.g., ≥20 mm/kV). - Temperature Range: Typically -40°C to +70°C. Maintenance and Testing Routine inspections should verify: - Insulation integrity (via megger tests). - Seal condition to prevent moisture ingress. - Contact resistance to ensure efficient current transfer. Conclusion The TG3-12-110×180 Through Wall Bushing is a vital link in high-voltage infrastructure, combining advanced insulation technology with rugged construction. Its design prioritizes safety, efficiency, and adaptability, making it indispensable for modern electrical networks. Proper selection and maintenance ensure uninterrupted operation in critical power systems.
