TG1-12-100×100 Epoxy Resin Through Wall Bushing – Technical Description The TG1-12-100×100 Epoxy Resin Through Wall Bushing is a high-performance electrical insulation component designed for secure and reliable cable or conductor penetration through walls, partitions, or enclosures in medium to high-voltage applications. This bushing ensures electrical isolation, mechanical protection, and environmental sealing while maintaining structural integrity in demanding industrial, utility, or infrastructure settings. Design and Construction - Material: The bushing is manufactured using epoxy resin, a thermosetting polymer known for its excellent dielectric strength, thermal stability, and resistance to moisture, chemicals, and UV degradation. The epoxy encapsulation provides robust insulation and long-term durability. - Dimensions: The designation 100×100 indicates a square flange profile (100mm × 100mm), ensuring a stable mounting surface. The through-hole diameter accommodates cables or conductors up to specified sizes, with precise tolerances for a snug fit. - Voltage Rating: Rated for 12kV (TG1-12), this bushing is suitable for medium-voltage systems, complying with international standards for electrical safety and performance. Key Features 1. Electrical Insulation: The epoxy resin’s high dielectric strength prevents current leakage or flashover, even in humid or contaminated environments. 2. Mechanical Strength: Reinforced with embedded materials (e.g., fiberglass or silica fillers), the bushing resists cracking, vibration, and mechanical stress. 3. Environmental Protection: Seals penetrations against dust, moisture, and corrosive gases, making it ideal for outdoor or harsh indoor installations. 4. Flame Retardancy: Self-extinguishing properties meet fire safety standards (e.g., UL94 V-0). 5. Easy Installation: Pre-drilled mounting holes or threaded inserts simplify attachment to walls or panels without specialized tools. Applications - Power Distribution: Cable terminations in substations, transformers, or switchgear. - Renewable Energy: Wind turbines, solar farms, or battery storage systems. - Industrial Equipment: Machinery, control cabinets, or underground mining installations. - Transportation: Tunnels, railways, or marine infrastructure requiring corrosion-resistant solutions. Standards Compliance The bushing adheres to IEC, IEEE, or ANSI standards for electrical insulation, partial discharge, and thermal cycling performance. Advantages Over Alternatives - Epoxy vs. Porcelain: Lighter weight, superior impact resistance, and no risk of ceramic cracking. - Epoxy vs. Silicone: Higher rigidity and better long-term stability under thermal loads. Installation Notes - Ensure the wall penetration is clean and debris-free. - Use compatible sealing gaskets or adhesives for airtight/watertight performance. - Verify voltage and current ratings match system requirements. Conclusion The TG1-12-100×100 Epoxy Resin Through Wall Bushing is a critical component for safe, durable, and efficient electrical penetrations. Its epoxy construction delivers unmatched insulation, environmental resilience, and ease of integration, making it a preferred choice for engineers prioritizing reliability in high-voltage infrastructure.
