TG4-12-140×200 isolado através de bucha de parede

TG4-12-140×200 Insulated Through Wall Bushing – Technical Description The TG4-12-140×200 Insulated Through Wall Bushing is a high-performance electrical component designed to facilitate the safe and efficient passage of conductors through walls, barriers, or enclosures in medium- to high-voltage applications. This bushing ensures reliable insulation, mechanical stability, and environmental protection, making it suitable for demanding industrial, utility, and infrastructure installations. Design and Construction The bushing features a robust cylindrical design with an insulated body, typically constructed from high-grade materials such as silicone rubber, epoxy resin, or porcelain. These materials provide excellent dielectric strength, thermal resistance, and resistance to environmental factors like moisture, UV radiation, and chemical exposure. The 140×200 mm dimensions indicate the flange or mounting interface size, ensuring compatibility with standard wall penetrations. Electrical Performance Rated for 12 kV applications, the TG4-12 bushing is engineered to withstand high voltages while minimizing electrical losses and partial discharge. Its insulation system is optimized to prevent flashovers and leakage currents, ensuring long-term reliability in harsh conditions. The conductive core (usually copper or aluminum) is designed to handle specified current ratings, with low resistance to reduce heat generation. Mechanical and Environmental Features - Sealing and Protection: The bushing incorporates gaskets or sealing rings to prevent ingress of dust, water, or gases, meeting IP66 or higher ingress protection standards. - Temperature Resistance: Operates reliably across a wide temperature range (e.g., -40°C to +120°C), suitable for outdoor or extreme environments. - Flange Design: The flange ensures secure mounting via bolts or clamps, with corrosion-resistant finishes (e.g., galvanized or stainless steel) for durability. Applications This bushing is widely used in: - Power distribution systems (e.g., transformers, switchgear). - Renewable energy installations (solar/wind farms). - Industrial plants requiring wall penetrations for cables or busbars. - Transportation infrastructure (tunnels, substations). Compliance and Safety The product complies with international standards such as IEC, IEEE, or ANSI, ensuring safety and performance. Its flame-retardant properties and pollution-resistant design further enhance operational safety. Installation and Maintenance Installation involves securing the bushing into a pre-cut wall opening, ensuring proper alignment and torque for flange bolts. Routine inspections should check for cracks, contamination, or seal degradation to maintain performance. Conclusion The TG4-12-140×200 Insulated Through Wall Bushing is a critical component for safe electrical transitions through barriers, combining high insulation integrity, mechanical robustness, and environmental resilience. Its versatility and compliance with industry standards make it a trusted solution for diverse high-voltage applications. (Word count: 500)
