The electric crossbar, crafted from robust angle iron, is an essential component laterally affixed to the summit of electric poles, serving as a critical fixture in the structural integrity of the poles.
1. Functions and Uses
Wire Support: The cross-loader is ingeniously designed to host insulators and metallic fittings that provide steadfast support for wires and lightning protection conduits, all while adhering to regulated safety distances.
Installation Equipment: The versatile crossbar is indispensable for mounting line apparatus, including switching equipment and lightning arresters, ensuring seamless operational efficiency.
2. Type and Structure
Type: Tailored to specific applications and load conditions, cross-loads are categorized into straight-load, tension-load, corner-load, etc. The straight cross-body predominantly accommodates vertical and horizontal wire loads; tension-resistant cross-bodies also absorb wire tension variations alongside the standard loads; corner cross-bodies are engineered to handle substantial single-sided wire tension.
Structure: Typically constructed from resilient metal materials such as angle steel, the crossbar boasts superior support capabilities. Certain variants, like fiberglass crossbars, offer remarkable dielectric properties, exceptional mechanical strength, and enhanced corrosion resistance, owing to specialized materials or treatments.
III. Installation and Maintenance
Installation Position: Strategically positioned 300mm from the rod's apex, the straight cross-bar is installed on the power receiving side, whereas the angle rod, terminal rod, and branch rod cross-bars are mounted on the pull-bar side for optimized load distribution.
Installation Method: Ensuring robust and secure attachment, the crossbar can be affixed to telephone poles using bolts, welding, or alternative methods suited to the pole type and line specifications, adapting to diverse installation needs.
Maintenance: Conduct routine inspections to ascertain the crossbar's pristine condition. Promptly address any signs of corrosion, deformation, or damage by executing timely repairs or replacements.
4. Characteristics and Advantages
Superior Support: Engineered to endure significant weight and tension, the cross-load provides a steadfast platform, ensuring unwavering support for an array of power lines.
Versatile Installation Methods: The crossbar's adaptable installation techniques cater to a variety of telephone pole configurations and line requirements, offering unparalleled flexibility.
Auxiliary Insulation: While not the primary insulating element, the crossbar can occasionally contribute to insulation, enhancing overall system efficiency.
