Product Description

Composite Cross Arm Insulatordesigned to enhance functionality and safety.

These Composite Cross Arm Insulator are designed to improve the functionality and safety of overhead distribution lines. Featuring an integrated structure - comprising a high-strength fiberglass-reinforced plastic (FRP) core, a high-temperature vulcanized (HTV) silicone rubber housing, and hot-dip galvanized steel fittings - they strike an optimal balance between electrical insulation and mechanical load-bearing capacity, effectively meeting the grid's critical needs for both line insulation and structural support.

Composite Cross Arm Insulator is external silicone rubber housing exhibits excellent hydrophobicity. It delivers outstanding performance regarding electrical stress resistance and pollution tolerance in harsh environments - such as areas with high salt spray, heavy industrial dust, coastal locations, or complex high-altitude regions with low atmospheric pressure - thereby ensuring the long-term, efficient operation of distribution lines under severe conditions.

Composite Cross Arm Insulator Offering advantages such as environmental friendliness, low maintenance requirements, and operational reliability, these insulators serve as a superior alternative to traditional porcelain insulators. They are lighter in weight, resulting in reduced labor costs and simplified on-site transport and installation processes. Despite their lighter weight, they possess excellent mechanical strength and corrosion resistance; furthermore, they require no anti-corrosion treatment throughout their long service life, significantly easing the burden on maintenance personnel.

Our insulators are manufactured in accordance with IEC standards and undergo rigorous factory testing. We can customize product dimensions, creepage distances, and other specifications to meet specific customer design requirements.

Each insulator undergoes rigorous testing before leaving the factory to ensure compliance with IEC standards. Manufacturers can optimize product dimensions and creepage distances based on various design specifications and grid connection requirements, providing a cost-effective solution for both the maintenance of existing distribution networks and the construction of new lines.

Product Advantage

1. Integrated Linear Design

This product combines structural support and line insulation into a single unit, merging the advantages of both functions to create a design characterized by structural simplicity and an orderly layout.

2. Corrosion and Aging Resistance; No Annual Maintenance Required

Unlike traditional metal fittings susceptible to corrosion and aging, this composite product offers excellent corrosion resistance and remains unaffected by acidic or alkaline environments. Suitable for use in coastal areas, mining sites, and chemical industrial parks, it offers long-term durability without the need for anti-corrosion coatings or annual maintenance.

3. Enhanced Operational Safety

Its inherent insulation design effectively prevents common line faults - such as conductor rotation, phase-to-phase discharge, and short circuits caused by insufficient conductor spacing - thereby significantly improving the overall safety and operational performance of the transmission line.

4. Lightweight Design for Cost Reduction

The product's lightweight nature reduces the load on towers and poles; additionally, the simplified installation process drastically cuts down on on-site construction time.

5. Weather and Aging Resistance; Long Service Life

Manufactured from high-quality silicone rubber, the product exhibits exceptional UV and weather resistance. It withstands aging and performance degradation during prolonged outdoor exposure, ensuring stable mechanical strength and reliable protective performance.

FAQ

Q: 1. What are the main differences between this product and standard insulators?

A: It serves a dual function: providing structural support while also acting as an insulator. It can replace the "traditional insulator + separate disconnector" combination, thereby simplifying the design of overhead transmission lines.

Q: 2. For which voltage levels are this product suitable?

A: It is primarily designed for 10 kV, 20 kV, and 35 kV overhead transmission lines; the product's thickness and operating parameters can be adjusted according to specific project requirements.

Q: 3. Is the product prone to corrosion (rusting)?

A: It does not rust. The core is made of composite materials, and only the connecting parts are made of galvanized low-carbon steel. Unlike traditional equipment, it offers exceptional durability and requires no periodic anti-rust painting.

Q: 4. What are the advantages regarding installation?

A: It is lightweight, reducing the load on the structure. It requires fewer additional components and allows for faster installation, thereby saving on labor hours and material costs.

Q: 5. What are the product's operational characteristics?

A: It is suitable for harsh environments that cause corrosion and material aging, such as coastal areas with salty air, or environments exposed to coal dust or heavy pollution.

Q: 6. How is product quality controlled?

A: Each unit undergoes mechanical and electrical performance testing before leaving the factory to ensure compliance with IEC standards; relevant test reports are provided.
