Wall through bushings are critical components in medium and high voltage electrical systems, ensuring the safe passage of current-carrying conductors through grounded barriers such as walls or panels. With growing demand for compact substations and reliable grid infrastructure, the performance and insulation quality of bushings are receiving more attention than ever.
One of the most important considerations for users is long-term reliability. A high-quality wall through bushing must maintain strong dielectric performance even in challenging environments. This includes resistance to moisture, contamination, and thermal cycling, especially in outdoor or partially exposed installations. Epoxy resin and silicone rubber are commonly used for enhanced insulation and mechanical strength.
