The Secondary Rack is an auxiliary device used in power line infrastructure, also known as secondary rack electrical equipment. Typically installed on the side or inside of a utility pole, its primary function is to support cables, help tighten sagging conductors, and ensure the stability and safety of power transmission.
Variety of Types: Jinmai Powerline offers four types of Secondary Racks, categorized based on the number of spools: 2-spool, 3-spool, 4-spool, and 5-spool.
Material and Construction: The base of these secondary racks is a steel U-channel, connected to the utility pole with bolts and nuts. Curved slots on the U-channel are used to secure the curve racks, each with a hole at the end for a 5/8-inch stud to pass through.
Safety Design: To protect linemen from sharp edges, the ends of the racks are stamped out.
Corrosion Resistance: The surface of the Secondary Rack is hot-dip galvanized according to the ASTM-123 standard, resulting in a smooth, rib-free surface for excellent corrosion resistance.
Design and Engineering:The process begins with the design and engineering phase, where skilled engineers create detailed blueprints and specifications for the Secondary Racks. These designs are tailored to meet the specific requirements of the power line infrastructure projects and customer needs.
Material Selection: High-quality steel is chosen as the primary material for its strength and durability. The steel is selected based on the gauge specified in the product specifications, ensuring the Secondary Racks can withstand the rigors of outdoor installations.
Cutting and Forming: The steel is cut to the required lengths and shapes using advanced cutting machines. The U-channel base and curve racks are then formed using press brakes and bending machines, which provide precision and consistency in the manufacturing process.
Drilling and Tapping: Holes are drilled at precise locations for the mounting holes and any other necessary connections. Tapping is performed to create internal threads for the bolts and nuts that will secure the Secondary Racks to the utility poles.
Edge Treatment: To ensure safety and prevent injuries from sharp edges, the ends of the racks are carefully stamped out or rounded using specialized equipment.
Galvanization: The Secondary Racks undergo a hot-dip galvanization process to provide a protective coating against corrosion. This process involves immersing the steel components in molten zinc, resulting in a smooth, rib-free surface that offers excellent resistance to the elements.
Quality Control: Each Secondary Rack is inspected for quality and adherence to specifications. This includes checking the dimensions, strength, and integrity of the welds, as well as the overall finish of the galvanized surface.
Packaging and Shipping: Once the Secondary Racks pass the quality control checks, they are packaged to protect them during transportation. The packages are labeled with necessary information and shipped to customers or storage facilities.
Customization: For customers requiring customization, the manufacturing process may include additional steps such as modifying the design, adjusting the dimensions, or applying special coatings or finishes.
