Product Description
Aerial Bundle Cable : Product Description and Specifications
The Aerial Bundle Cable (ABC) series configures insulated overhead conductors for critical LV and MV distribution. Unlike legacy bare wire, this XLPE-insulated design (utilizing AAAC/1350-H19 aluminum) creates a safety-critical barrier, minimizing maintenance requirements. Application Scope: Ranges from 0.6/1kV service drops/lighting to 33kV primary feeders. Structural Options: Manufactured with either an integrated supporting messenger or self-supporting lay, depending on span engineering requirements.

Production Processes Of Aerial Bundle Cable
The aerial cable manufacturing infrastructure operates a closed-loop digital automation system, integrating conductor stranding, insulation extrusion, and final sheathing into a continuous workflow. Process stability relies on embedded sensor arrays tracking extrusion parameters in real-time, eliminating manual variances. Quality validation is enforced through specific in-line hardware, including dual-axis laser diameter gauges and high-voltage spark testers, while the physical laboratory conducts destructive tensile and elongation analysis to verify compliance with international standards before shipment.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
