TG3-12-110×180 Electrical Wall Bushing – Technical Description The TG3-12-110×180 Electrical Wall Bushing is a high-voltage insulating component designed for safe and reliable electrical transmission through walls, partitions, or enclosures in power distribution systems. It serves as a critical interface, ensuring insulation and mechanical stability while allowing conductors to pass through grounded barriers without compromising safety or performance. Design and Construction This wall bushing features a robust design tailored for medium to high-voltage applications (rated for 12 kV). Its cylindrical body, with dimensions of 110 mm in diameter and 180 mm in length, is constructed from high-quality, weather-resistant materials such as porcelain or composite polymers. These materials provide excellent dielectric strength, thermal stability, and resistance to environmental stressors like UV radiation, moisture, and chemical exposure. The bushing incorporates a central conductor (typically copper or aluminum) insulated by layers of dielectric material. The flanged base ensures secure mounting onto walls or panels, while silicone or epoxy seals prevent moisture ingress. The design may include grading rings or shielding layers to manage electric field distribution and minimize partial discharges. Key Features 1. Voltage Rating: Suitable for systems up to 12 kV, complying with IEC or ANSI standards. 2. Current Capacity: Designed to handle specified ampacity without overheating. 3. Mechanical Strength: Resists mechanical stress from conductor weight, wind, or seismic activity. 4. Environmental Protection: IP67 or higher ingress protection for outdoor/indoor use. 5. Fire Resistance: Self-extinguishing materials to enhance safety. Applications - Substations: Feedthrough connections in switchgear or transformer compartments. - Renewable Energy: Integration in solar/wind farm power distribution. - Industrial Plants: Cable pass-through in control panels or HV equipment. Installation & Maintenance Installation requires proper alignment and torqueing of mounting hardware to avoid mechanical strain. Periodic inspections for cracks, contamination, or seal degradation are recommended to ensure longevity. Advantages - Reliable Insulation: Prevents flashovers and short circuits. - Durability: Long service life under harsh conditions. - Safety: Minimizes risk of electrical faults in grounded systems. In summary, the TG3-12-110×180 Electrical Wall Bushing is an essential component for secure, high-voltage electrical transitions, combining robust engineering with stringent safety standards for diverse industrial applications.
