Applications
A. Power Transformer Field
High - Voltage Side: Equipped with oil - paper capacitor type bushings that integrate fiber optic temperature measurement, enabling real - time monitoring and better thermal management compared to some traditional bushings without such advanced monitoring capabilities.
Dry - Type Transformer: Utilizes epoxy resin sleeves with a moisture - proof design, enhancing durability in various environmental conditions, an improvement over bushings that may be more vulnerable to moisture - related degradation.
B. Switchgear/GIS Equipment
Busbar Through - Wall Sleeve: Epoxy resin casting supports hot plugging, ensuring seamless operations, which is a more convenient and efficient feature than non - hot - plug - compatible alternatives.
GIS Sleeve: Provides SF6 gas insulation with a coaxiality error of ≤ 0.1mm/m and seismic grade 8 resilience, offering better insulation and seismic performance compared to bushings with lower coaxiality accuracy and seismic resistance.
C. New Energy Systems
In offshore wind power, it is equipped with composite casings resistant to salt spray, providing superior anti - corrosion protection, a significant advantage over bushings that may corrode more easily in salt - laden environments, ensuring longer - term stable operation in harsh marine conditions.
D. Industry and Transportation
High - Voltage Motor Lead - Out: Features a flexible sleeve that absorbs vibration, enhancing stability, which is better for motor operation than rigid bushings that may transfer vibration and cause potential damage.
Rail Transit Traction Power Supply: Explosion - proof design withstands frequent start - stop cycles, a crucial safety and durability feature compared to non - explosion - proof or less durable alternatives in this high - demand application scenario.
Nanjing Rainbow Electric Co. ensures that your electrical infrastructure remains efficient and safe with our high-quality 1kV Epoxy Bushing.
Competitive Edge
A. Insulation and Durability
When compared to similar products in the market, this epoxy bushing stands out in insulation. The capacitive design outperforms many competitors' designs in achieving uniform electric field distribution, thus providing more reliable high - voltage insulation. In terms of durability, the epoxy resin construction, with its resistance to dirt and moisture, ensures a longer service life with minimal maintenance, surpassing those that are more prone to environmental damage.
B. Application Versatility
Its application scope is broad, covering power transformers, switchgear/GIS equipment, new energy systems, and more. In power transformers, it can be used for both oil - paper capacitor type bushings on the high - voltage side (with integrated fiber optic temperature measurement) and epoxy resin sleeves for dry - type transformers (with a moisture - proof design). For switchgear/GIS equipment, it functions as a busbar through - wall sleeve (supporting hot plugging) and a GIS sleeve (offering SF6 gas insulation with high coaxiality accuracy and good seismic resilience). In new energy systems like offshore wind power, it has composite casings resistant to salt spray. This versatility makes it a more adaptable choice than many competitors that may be limited to specific application fields.
C. Customization and Quality
Offers customizable solutions to meet specific requirements, a feature that not all competitors can match. Adheres to strict quality control standards, meeting international norms, which ensures its reliability and safety in high - voltage insulation applications, putting it ahead of products with looser quality management.
