The electric crossbar is a robust angle iron component, expertly crafted to be laterally affixed atop the electric pole. This integral piece plays a pivotal role in maintaining the pole's structural integrity and function.
1. Functions and Uses
Support Wire: The cross-loader is ingeniously designed to install insulators and metal tools, effectively supporting wires and lightning protection wires. It adheres to regulatory standards by ensuring a precise and safe distance is maintained at all times.
Installation Equipment: This crossbar is also crucial for the installation of line equipment, including sophisticated switching devices, lightning arresters, and more, ensuring seamless operation.
2. Type and Structure
Type: Based on their purpose and stress conditions, cross-loads are classified into straight-load, tension-load, and corner-load. Straight cross-bodies bear both vertical and horizontal wire loads; tension-resistant cross-bodies handle vertical, horizontal, and wire tension differences; corner cross-bodies manage significant unilateral wire tension effectively.
Structure: Typically constructed from robust metal materials like angle steel, the crossbar offers exceptional support. Some variants are crafted from special materials or undergo unique treatments, such as fiberglass crossbars, known for their superior dielectric properties, high mechanical strength, and remarkable corrosion resistance.
III. Installation and Maintenance
Installation Position: Typically positioned 300mm from the top of the rod, the straight cross-bar is installed on the power-receiving side, whereas the angle rod, terminal rod, and branch rod cross-bars are installed strategically on the pull-bar side for optimal stability.
Installation Method: The crossbar can be securely attached to the telephone pole using bolt connections, welding, and other reliable methods. Depending on pole types and line specifications, varying installation techniques can be utilized to ensure maximum stability and reliability.
Maintenance: Regular inspections and maintenance are essential to keep the crossbar in pristine condition. Immediate replacement or repair is necessary if corrosion, deformation, or damage is detected, ensuring continued performance and safety.
4. Characteristics and Advantages
Good Support: With an ability to handle substantial weight and tension, the cross-load offers a stable and reliable support platform for a multitude of power lines, ensuring seamless functionality.
Various Installation Methods: The crossbar boasts a versatility in installation techniques, adaptable to diverse types of telephone poles and line requirements, ensuring it meets all operational demands.
Certain Insulation Performance: While not the primary insulation component, the crossbar can provide auxiliary insulation in certain scenarios, contributing to overall safety and reliability.
