The electric crossbar, a robust angle iron component, is expertly laterally affixed to the top of the electric pole, playing a pivotal role as a fundamental component in ensuring the integrity and functionality of the pole.
1. Functions and Uses
Wire Support: The cross-loader is essential for installing insulators and metal tools, effectively supporting both power and lightning protection wires. It ensures adherence to regulatory safety distances, thereby facilitating secure and efficient electrical distribution.
Installation of Equipment: Beyond its primary function, the crossbar proficiently accommodates the installation of critical line equipment such as switching devices and lightning arresters, enhancing the pole's operational capabilities.
2. Type and Structure
Type: Cross-loads are classified based on their purpose and stress conditions into categories such as straight-load, tension-load, and corner-load. The straight cross-body primarily handles vertical and horizontal wire loads; the tension-resistant variant also manages wire tension differences, while the corner version withstands significant single-sided wire tension.
Structure: Typically constructed from resilient metal materials like angle steel, the crossbar boasts superior support. Some variants, such as those made from fiberglass, offer excellent dielectric properties, high mechanical strength, and robust corrosion resistance, tailored for specific environmental demands.
III. Installation and Maintenance
Installation Position: Strategically placed 300mm from the rod's top, the straight cross-bar is installed on the power receiving side. In contrast, angle, terminal, and branch rod cross-bars are mounted on the pull-bar side, ensuring optimal structural stability.
Installation Method: The crossbar can be securely affixed to the telephone pole through reliable bolt connections or welding, guaranteeing a stable installation. Different types of poles and line requirements dictate the use of various installation techniques, ensuring adaptability to diverse scenarios.
Maintenance: Regular inspections and maintenance of the crossbar are crucial to ensure its optimal condition. Any signs of corrosion, deformation, or damage necessitate immediate repair or replacement to maintain safety and efficacy.
4. Characteristics and Advantages
Superior Support: The cross-load is engineered to endure significant weight and tension, providing a stable and reliable support platform for diverse power lines, thus reinforcing the pole's structural integrity.
Variety of Installation Methods: With its diverse installation options, the crossbar is versatile enough to meet the varying needs of different types of telephone poles and line requirements, ensuring comprehensive adaptability.
Insulation Capabilities: While not primarily designed for insulation, the crossbar can offer auxiliary insulation benefits in certain scenarios, contributing to the overall safety of the electrical system.
