Single Spool,Secondary Rack

Product Description：

The Hot Dip Galvanized ASTM A153 Single Spool Secondary Rack is a durable and corrosion-resistant pole line hardware solution used in low-voltage and medium-voltage distribution systems. Manufactured with high-strength steel and finished with hot dip galvanizing compliant with ASTM A153, this Single Spool Secondary Rack provides long-term outdoor protection and ensures secure conductor support in power networks. The Hot Dip Galvanized ASTM A153 Single Spool Secondary Rack is widely used in overhead line installations, transformer poles, service drops, and utility distribution infrastructure. Its rugged structure and stable load-bearing performance make it suitable for harsh environments, including coastal regions, high-humidity areas, and industrial atmospheric exposure.

Product Advantages：

1. Hot dip galvanized coating ensures exceptional corrosion resistance

2. High structural strength for long-term outdoor service

3. Compatible with multiple spool insulators and line hardware

4. Easy installation, suitable for both new and retrofit projects

5. Low maintenance and long operational lifespan
   

Application Scenarios：

Widely used in overhead power distribution systems, especially for mounting secondary electrical wires on wood or concrete utility poles in urban and rural areas.
