Galvanized Steel Crossarms: Professional Power Line Support Solutions

           Galvanized Steel Crossarms: Professional Power Line Support Solutions

As professional product engineers at Shandong Weichite Electric Power Technology Co., Ltd., we understand that the reliability of every component is critical in power line construction. Today, we will provide a detailed introduction to our flagship galvanized steel crossarm products, helping you gain a comprehensive understanding of this indispensable key component in power lines.

What Are Galvanized Steel Crossarms?

Galvanized steel crossarms serve as vital electrical hardware components at tower sections in overhead lines. Primarily used atop utility poles to support overhead circuits, install lightning arresters, and mount insulators, our crossarms are crafted from premium steel and undergo hot-dip galvanization to ensure exceptional corrosion resistance and extended service life.

Our Product Advantages

1. Superior Corrosion Resistance

Outdoor power facilities endure constant exposure to wind and rain, demanding exceptional corrosion protection. Our galvanized steel crossarms feature a hot-dip galvanized coating with strong zinc adhesion, delivering high corrosion resistance and extended protection against harsh environmental corrosion, significantly extending service life.

2. Superior Mechanical Strength

Crossarms bear multiple forces in overhead lines, including vertical loads, horizontal loads, and conductor tension, demanding high mechanical strength. Manufactured from high-strength steel and subjected to precise calculations and rigorous testing, our products fully meet engineering load-bearing requirements.

3. Comprehensive Model Range

We offer various models of galvanized steel crossarms to suit diverse application needs. By application, they are categorized as: straight crossarms, angle crossarms, and tension crossarms. Whether it's the commonly used angle steel specifications like L63*5 and L80*6 for 10KV high-voltage lines, or specialized four-wire crossarms for specific requirements, we can provide the corresponding products.

4. Rational Structural Design

Our galvanized C-type crossarms feature a rational structural design, offering high bending strength and stiffness per unit cross-sectional area. Compared to traditional angle steel crossarms, our products offer the following advantages:

Material savings: 40*20*10 galvanized C-type crossarms can replace No. 3, No. 4, and No. 5 angle steel, reducing raw material costs

Space efficiency: With a height of only 20mm, they save 10-30mm of installation space

Aesthetic appeal: Through-threaded suspension heads and fastening bolts are concealed within the C-channel, ensuring a clean appearance.

Application Scenarios

Our galvanized steel crossarms are widely used for:

- Top mounting on various utility poles

- Support and fixation of branch cables

- Installation of overhead switches and disconnectors

Suitable for various pole types including angle poles, tension poles, terminal poles, and branch poles

Particularly suitable for 10kV high-voltage line construction. Single or double crossarms can be selected based on load conditions: single crossarms for straight poles or angle poles under 15 degrees, while double crossarms are used for angle poles over 15 degrees, tension poles, terminal poles, and branch poles [CITATION:10].

Technical Specifications

Our galvanized steel crossarm models are comprehensive. Taking the common model ∠63×6×2000D=260 as an example:

- ∠63×6×2000 denotes crossarm dimensions: 63mm angle steel, 6mm thickness, 2000mm length

- D=260 denotes the diameter of the utility pole

For four-wire crossarms used in high-voltage lines, we strictly adhere to standard specifications in design and manufacturing to ensure safety and reliability.
