产品详情
The 35kV crossarm composite insulator is an important insulating and supporting component for medium and high voltage overhead distribution lines. It is designed to support conductors, provide reliable electrical insulation, and improve line structure performance. Compared with traditional porcelain insulators or steel crossarm systems, Wishpower 35kV crossarm composite insulators offer lightweight construction, high mechanical strength, excellent anti-pollution performance, aging resistance, and easier installation for outdoor power distribution projects.
Main product advantages include:
Reliable insulation performance: Silicone rubber housing provides excellent hydrophobicity and hydrophobicity transfer, reducing flashover risk in polluted environments.
Lightweight design: Composite material structure makes the product easier to transport, install, and maintain.
High mechanical strength: The fiberglass core rod provides good bending, tensile, and impact resistance.
Excellent weather resistance: Suitable for outdoor environments with UV exposure, rain, snow, humidity, salt fog, and temperature variation.
Lower maintenance cost: The product is resistant to breakage, pollution, and corrosion, helping reduce inspection and replacement frequency.
Suitable for line upgrading: Ideal for overhead distribution line insulation improvement and traditional crossarm replacement projects.
