The electric crossbar, an essential component crafted from angle iron, is strategically affixed laterally atop the electric pole. This vital element of the pole infrastructure serves as a linchpin in the stability and functionality of electrical systems.
1. Functions and Uses
Support Wire: The cross-loader is a pivotal tool in the installation of insulators and metal apparatus, crucial for supporting wires and maintaining a safe distance for lightning protection as stipulated by regulations.
Installation Equipment: Beyond its primary function, the crossbar is instrumental in the installation of line apparatus such as switching equipment and lightning arresters, ensuring seamless operation of electrical grids.
2. Type and Structure
Type: Tailored for specific purposes, cross-load options include straight-load, tension-load, and corner-load. The straight cross-body is designed to manage both vertical and horizontal wire loads; the tension-resistant variant also accommodates wire tension disparities; while the corner type manages significant single-sided wire tension with expertise.
Structure: Engineered from robust metal materials like angle steel, the crossbar ensures formidable support. Innovative designs may utilize special materials such as fiberglass, renowned for superior dielectric properties, exceptional mechanical strength, and notable corrosion resistance.
III. Installation and Maintenance
Installation Position: Typically, the crossbar is mounted 300mm from the rod's apex. Placement varies: straight cross-bars align with the power receiving side, whereas angle, terminal, and branch rod cross-bars are installed on the pull-bar side to optimize stability.
Installation Method: Securely affixing the crossbar to telephone poles is achievable through bolts, welding, and other methods, ensuring steadfast and reliable installation. Each installation method is carefully selected based on pole type and line specifications.
Maintenance: Regular inspections and maintenance are imperative to retain the crossbar's pristine condition. Prompt action is required to repair or replace it if signs of corrosion, deformation, or damage are detected, safeguarding system integrity.
4. Characteristics and Advantages
Good Support: The cross-load provides a robust foundation, enduring substantial weight and tension, which ensures a stable platform for various power lines, vital for uninterrupted power supply.
Various Installation Methods: The crossbar boasts a versatile array of installation techniques, enabling adaptation to diverse telephone pole types and specific line requirements for enhanced compatibility.
Certain Insulation Performance: Although not primarily an insulating component, the crossbar can offer auxiliary insulation benefits under specific conditions, adding an extra layer of safety to the electrical infrastructure.
