Key Features

Engineered For Performance

Non-Metallic FRP Core

FRP central strength member provides a non-metallic cable core, reducing lightning induction risk while the outer armor provides mechanical protection.

Hybrid Design Philosophy

Combines the benefits of non-metallic core (lightning safety) with steel tape armor (crush and rodent resistance) for versatile deployment scenarios.

Direct Burial Rated

Steel tape armor and aramid yarn reinforcement provide adequate mechanical protection for direct burial without additional conduit.

Lightweight Construction

FRP core reduces overall cable weight compared to all-steel designs, easing handling during installation while maintaining mechanical strength.

Typical Applications

01

Lightning-Prone Burial Routes

Direct burial in areas with high lightning activity where the FRP core minimizes lightning damage risk while armor protects against soil pressure and rodents.

02

Power Line Adjacent Burial

Underground cable routes near power infrastructure where the non-metallic core prevents electromagnetic interference from high-voltage lines.

03

Suburban Telecom Networks

Trunk and distribution fiber routes in suburban areas using direct trenching installation for cost-effective network deployment.
