Reduced weight, suitable for aerial installation

InArmor+ FRP is a multi-tube all-dielectric and UV-resistant cable with fiberglass rods armor ensuring excellent rodent resistance. This design features reliable protection from serious mechanical impact. Its maximum rated design tension can be up to 4,496 lb and resistance to crushing load can reach up to 571 lb/in. Due to reduced weight, it is suitable for aerial installation. It has a wide range of operating temperatures from -40°F to +158°F and installation temperatures from +14°F to +122°F (operating temperature range can be increased on request).

InArmor+ FRP consists of a stranded core with central strength member (FRP) and loose tubes with optical fibers (up to 144). The stranded core is fixed by water-swellable yarns. The armor consists of FRP rods. There are water-swellable yarns between an inner jacket and FRP rods.

Typical application:

  • Aerial installation between poles and buildings
  • Aerial installation on powerlines
  • Aerial installation for communication lines
  • Pulling into underground ducts and sewer pipes
  • Installation along bridges, tunnels and other structures
  • Installation into indoor/outdoor cable conduits and trays
