TG1-12-100×100 Epoxy Bushing: Technical Overview The TG1-12-100×100 Epoxy Bushing is a high-performance insulating component designed for medium-voltage electrical applications, typically rated for 12 kV systems. Its robust construction and advanced material composition ensure reliable insulation, mechanical strength, and resistance to environmental stressors, making it suitable for transformers, switchgear, and other power distribution equipment. Design and Construction The bushing features a 100×100 mm square flange design, providing a stable mounting interface for secure installation. The core insulation is made of epoxy resin, a thermosetting polymer known for its excellent dielectric properties, thermal stability, and resistance to moisture, chemicals, and partial discharge. The epoxy is reinforced with high-grade fillers to enhance mechanical durability and prevent cracking under thermal or electrical stress. The central conductor, typically copper or aluminum, is embedded within the epoxy body to ensure optimal current-carrying capacity while maintaining electrical isolation from grounded surfaces. The bushing’s smooth, molded surface minimizes corona effects and reduces the risk of surface tracking, even in polluted or humid environments. Key Features 1. High Dielectric Strength: The epoxy insulation withstands high electric fields, ensuring safe operation at rated voltages. 2. Thermal Stability: Operates reliably across a wide temperature range (-40°C to +120°C) without degradation. 3. Mechanical Robustness: Resists vibration, impact, and mechanical stress, ideal for harsh industrial settings. 4. Flame Retardancy: Self-extinguishing properties comply with international safety standards (e.g., IEC, UL). 5. Corrosion Resistance: Immune to rust, oxidation, and chemical exposure, ensuring long-term performance. Applications - Transformers: Provides insulated passthroughs for high-voltage windings. - Switchgear/Circuit Breakers: Isolates live conductors in metal-enclosed systems. - Renewable Energy Systems: Used in solar/wind power inverters and substations. - Industrial Equipment: Suitable for motors, generators, and capacitor banks. Installation and Maintenance The bushing is designed for easy mounting via bolts or clamps, with torque specifications provided to avoid over-tightening. Routine inspections should check for surface contamination, cracks, or thermal discoloration. No specialized maintenance is required under normal conditions. Conclusion The TG1-12-100×100 Epoxy Bushing combines advanced materials and precision engineering to deliver dependable insulation in demanding electrical systems. Its compact design, superior performance, and durability make it a preferred choice for modern power infrastructure.
