Introduction
Medium voltage systems are the backbone of modern electrical distribution, linking high voltage transmission networks to end-users, industrial plants, and renewable energy facilities. Ensuring the safety, efficiency, and reliability of these systems requires high-quality components that can endure mechanical, thermal, and electrical stresses over extended periods. Among these components, 12KV/24KV epoxy resin bushings are crucial for providing secure insulation, mechanical stability, and environmental protection.
Degatech’s epoxy resin bushings are engineered to meet the demands of medium voltage equipment. Their composite materials, advanced design, and customizable features make them ideal for transformers, switchgear, current transformers, reactors, and other electrical devices. By integrating these bushings into a system, engineers can reduce maintenance costs, improve operational safety, and ensure long-term performance.

Understanding Epoxy Resin Technology
Epoxy resin bushings differ from traditional porcelain bushings in several key aspects. They are composed of unsaturated polyester resin reinforced with glass fibers, creating a lightweight yet highly durable composite material. This structure provides excellent dielectric strength, mechanical integrity, and resistance to environmental stressors such as moisture, UV radiation, and chemical exposure.
The inclusion of metal inserts (brass, aluminum, or iron) ensures secure electrical connections while maintaining mechanical stability. These inserts allow for a reliable interface between the high-voltage conductor and the equipment, reducing the risk of electrical faults or failures. Compared to porcelain bushings, epoxy resin variants are less brittle, easier to handle, and more resistant to mechanical shock.
This combination of modern composite materials and precision engineering ensures that Degatech epoxy resin bushings provide both safety and reliability, making them a preferred choice for medium voltage installations.
