Secondary Racks Overview

These racks provide a robust and highly stable mounting point for any secondary rack insulator within the electrical network.

  • Constructed entirely from high-strength carbon steel.
  • Hot-dip galvanized strictly according to ASTM A-153 standards.
  • Consists of a complete assembly: steel clevis, clevis base, clevis pin (or bolt), and a stainless steel cotter pin.
  • Manufactured to comply precisely with ANSI C135.7 industry specifications.

Secondary Racks Features

Integrating these Secondary Racks into your infrastructure guarantees a reliable setup backed by direct-factory B2B terms:

  • Fast Installation: Designed to be easily attached to utility poles using a standard pole bolt or secondary rack pole band clamps.
  • Durable Construction: Exact dimensions and the heavy galvanized coating guarantee a long working life and excellent wear resistance.
  • Custom Manufacturing: Can be produced exactly as per client drawings with consistently short lead times.
  • EPC Project Ready: Manufactured under ISO 9001, ISO 14001, and ISO 18001 quality controls, offering low-cost pricing and complete tender documents.

Secondary Racks Applications

Built to handle continuous mechanical loads, this hardware is strictly utilized for:

  • Attaching multiple spool insulators safely to utility poles.
  • Supporting two-wire, three-wire, four-wire, and five-wire secondary line systems.
  • Supplying continuous, high-volume material lots for low and medium-voltage (LV and MV) EPC projects.
