The electric crossbar, a crucial component crafted from robust angle iron, is expertly affixed laterally atop the electric pole, serving as an indispensable element in ensuring the structural integrity and functionality of the pole.
1. Functions and Uses
Support Wire: The crossbar is ingeniously designed to accommodate the installation of insulators and metallic attachments, ensuring steadfast support for wires and lightning protection lines. It dutifully maintains a regulated safe distance, in compliance with industry standards.
Installation Equipment: Beyond its primary functions, the crossbar adeptly facilitates the installation of critical line apparatus, including switching devices and lightning arresters, thereby enhancing the pole's operational capability.
2. Type and Structure
Type: Cross-loads are categorized based on purpose and stress conditions into straight-load, tension-load, and corner-load variants. The straight cross-body gracefully manages the vertical and horizontal strains of the wire; the tension-resistant cross-body additionally accommodates the tension variance; the corner cross-body adeptly withstands pronounced single-sided tension.
Structure: Typically constructed from durable metal materials like angle steel for superior support, crossbars may also feature specialized materials or treatments. Options like fiberglass crossbars offer excellent dielectric properties, remarkable mechanical strength, and robust corrosion resistance.
III. Installation and Maintenance
Installation Position: Crossbars are strategically positioned about 300mm from the pole's apex. For optimal efficiency, the straight cross-bar should be placed on the power-receiving side, while crossbars on angle, terminal, and branch rods are best situated on the pull-bar side.
Installation Method: Securely affixing the crossbar to the telephone pole can be achieved through bolt connections, welding, and more. Choose the most reliable method based on the specific pole type and line requirements to guarantee stability and safety.
Maintenance: Routine inspections and maintenance of the crossbar are crucial to ensuring its optimal condition. Should you notice any corrosion, deformation, or damage, swift replacement or repair is imperative to maintain functionality.
4. Characteristics and Advantages
Robust Support: The crossbar is engineered to endure substantial weight and tension, delivering a reliable support platform for an array of power lines.
Flexible Installation: Featuring a variety of installation techniques, the crossbar is versatile enough to meet the diverse requirements of different telephone pole types and line configurations.
Auxiliary Insulation: While not the prime insulating element, the crossbar can, in certain scenarios, contribute beneficially to the insulating performance, reinforcing the safety of the installation.
