The epoxy resin wall bushing is primarily used to guide high-voltage conductors into or out of buildings, switchgear, and other electrical equipment through walls. It provides insulation and mechanical support, maintaining reliable electrical isolation and stability between the conductor and the wall. This ensures the safe and dependable operation of the power system. The 40.5kV rating indicates that the bushing is suitable for power systems with a rated voltage of 40.5kV.
Conductor:
Typically made of high-conductivity copper or aluminum, the conductor offers excellent electrical conductivity to carry the rated current, ensuring efficient power transmission. Its surface undergoes specialized treatment to reduce resistance and minimize eddy current losses, further enhancing transmission efficiency.
Insulation Layer:
The primary insulating material is epoxy resin, known for its exceptional electrical insulation, mechanical strength, and resistance to chemical corrosion. The epoxy resin insulation layer is formed using advanced casting techniques, creating a seamless bond with the conductor and external shielding layers. This design eliminates voids and impurities, effectively preventing partial discharge and insulation breakdown.
Shielding Layer:
The inner and outer surfaces of the insulation layer are typically equipped with shielding layers, made of metallic foil or conductive coatings. These layers distribute the electric field evenly, reducing field distortions and lowering local field intensity. This improves the bushing's insulation performance and operational reliability while preventing phenomena such as corona discharge.
Sealing Components:
High-performance sealing elements, such as rubber gaskets, are installed at the interface between the bushing and the wall. These seals effectively block moisture, dust, and other contaminants from entering the bushing, ensuring that insulation performance remains unaffected by external environmental factors. Additionally, the sealing components provide firm fixation and vibration damping, further enhancing durability.
