TG3A-40.5-395 Insulated Epoxy Resin Bushing Technical Description The TG3A-40.5-395 Insulated Epoxy Resin Bushing is a high-performance electrical component designed for medium-voltage applications, particularly in power distribution and transformer systems. This bushing is engineered to provide reliable insulation, mechanical strength, and long-term stability in demanding environments. Design and Construction The bushing features a robust design with an epoxy resin insulation system, which ensures excellent dielectric properties and resistance to environmental factors such as moisture, chemicals, and temperature fluctuations. The 40.5 kV rated voltage makes it suitable for medium-voltage networks, while the 395 mm creepage distance enhances its performance in polluted or humid conditions, minimizing the risk of surface flashover. The core of the bushing is constructed with high-quality conductive materials, typically copper or aluminum, ensuring efficient current transmission with minimal losses. The epoxy resin encapsulation provides a seamless, void-free insulation barrier, which enhances electrical performance and mechanical durability. Key Features 1. High Dielectric Strength – The epoxy resin insulation offers superior resistance to partial discharge and electrical breakdown, ensuring safe operation under high-voltage conditions. 2. Mechanical Robustness – The solid epoxy construction provides resistance to vibration, shock, and mechanical stress, making it ideal for transformer and switchgear applications. 3. Environmental Resistance – The bushing is resistant to UV radiation, moisture, and chemical exposure, ensuring long-term reliability in outdoor or harsh industrial environments. 4. Compact and Lightweight – Compared to traditional porcelain bushings, the epoxy resin design reduces weight and size while maintaining high performance. 5. Low Maintenance – The non-porous epoxy surface prevents contamination buildup, reducing the need for frequent cleaning or maintenance. Applications The TG3A-40.5-395 bushing is widely used in: - Power transformers (for HV/LV connections) - Switchgear and circuit breakers - Substation equipment - Renewable energy systems (wind and solar power installations) Standards and Compliance This bushing complies with international standards such as IEC 60137 and IEEE C57.19.00, ensuring compatibility with global electrical infrastructure requirements. Conclusion The TG3A-40.5-395 Insulated Epoxy Resin Bushing is a reliable and durable solution for medium-voltage applications, offering superior insulation, mechanical strength, and environmental resistance. Its advanced epoxy resin construction ensures long service life with minimal maintenance, making it a preferred choice for modern power systems. (Word count: 500)
