The robust electric crossbar serves as a pivotal component within electrical infrastructure. This angle iron, adeptly affixed laterally atop electric poles, is fundamental to their structural integrity.
1. Functions and Uses
Wire Support: The cross-loader is ingeniously designed to accommodate insulators and metal implements, providing essential support to both wires and lightning protection systems. It ensures compliance with safety distance regulations, enhancing operational reliability.
Installation Equipment: Beyond wire support, the crossbar is versatile in its application, facilitating the installation of crucial line equipment such as switching devices and lightning arresters, essential for optimal electrical performance.
2. Type and Structure
Type: Cross-loaders are categorized based on their intended use and stress conditions into straight-load, tension-load, and corner-load types. The straight cross-body primarily manages vertical and horizontal wire loads. The tension-resistant variant additionally withstands differential wire tension, while the corner type adeptly handles significant single-sided wire tension.
Structure: Constructed from durable metal materials like angle steel, the crossbar offers robust support. Variations may include specialized materials, such as fiberglass, known for its superior dielectric properties, high mechanical strength, and corrosion resistance.
III. Installation and Maintenance
Installation Position: Typically positioned 300mm from the rod’s apex, the straight cross-bar is placed on the power receiving side. Conversely, angle, terminal, and branch rod cross-bars are strategically installed on the pull-bar side to ensure stability.
Installation Method: Securely affixing the crossbar to utility poles via bolt connections or welding guarantees stability. Depending on the pole type and line specifications, adaptable installation methods ensure tailored and reliable setups.
Maintenance: Routine inspection and maintenance are crucial for preserving the crossbar’s condition. Should corrosion, deformation, or damage be detected, prompt replacement or repair is imperative to maintain system integrity.
4. Characteristics and Advantages
Robust Support: Capable of withstanding substantial weight and tension, the cross-load provides a reliable support platform crucial for diverse power line configurations.
Versatile Installation Methods: With its adaptable installation techniques, the crossbar seamlessly accommodates various pole types and line requirements, ensuring versatile application.
Auxiliary Insulation: While not the primary insulating component, the crossbar can occasionally contribute auxiliary insulation, adding an extra layer of protection where necessary.
