Optical Fiber Composite Ground Wire(OPGW)

Note: various types of stainless-steel tube are available as required.

Stainless Loose Tube Optical Fiber Unit Characteristics

Stainless tube provides higher modulus of elasticity, crush and impact resistance. Jelly filler prevents moisture or water penetration and providing good temperature characteristics. Better conducting heat, bigger specific heat volume and strength stability in high temperature. Design bigger fiber excess length, provide bigger stress-strain windows.

Composite Stainless Loose Tube Optical Fiber Unit Characteristics

- Ideally combine the well-rounded optical fiber second-coating technology with the advanced laser–welding stainless tube.

- Stainless tube with inner lining-effectively protects fibers from mechanical damage, such defects as burr, sawtooth formed during laser welding.

- Stainless tube, with inner lining tube, forms an organic whole with high strength adhesive, thereby has effective heat insulation for optical fibers.

- Fiber excess length has more uniformity and better consistency. The SUSP stainless tube needs no cold drawing, therefore the fiber excess length is effectively controlled.

- Totally waterproof structure can eliminate H2 damaged effect of moisture penetration.

Applications

Short-circuit current capacity Cross-section area of Al clad steel wire Cross-section area of Al-alloy wire

Replace existing aerial ground wires, upgrading communications lines of power systems. Synchronously plan and design with ground wire when new aerial power lines are to be constructed. Provide stainless tube fiber unit with optimal protection. Conduct fault short-circuit current and providing lightning protection.

Structure Characteristics

Small cable diameter, light weight, low additional load to poles/towers. The stainless steel tube fiber unit stands in the center of the strand layer. Obtain appropriate fiber excess length (primary) within stainless tube. With single armoring, the OPGW has a bit poor flexure and crush resistance, and a bit poor tensile strength. Obtaining the best balance of electric and mechanic performance by adjusting AA/AS Combination
