Straned OPGW Waterproof Fiber Optic Cable , Composite Overhead Ground Wire 205kN RTS

Technical Specifications for Optical Fiber Cable

Optical fibre composite overhead ground wire (OPGW) is an overhead ground wire containing optical fibre. It has multiple functions such as overhead ground wire and optical communication. It is mainly used for communication lines of 110KV, 220KV, 500KV, 750KV and new overhead high-voltage transmission system. It can also be used to replace the existing ground lines of the old overhead high voltage transmission system, add the optical communication line, transmit short time current and provide anti lightning protection. Other structures can be customized on request.

1. Replace existing aerial ground wires, upgrading communication lines of power systems.

2. Synchronous plan and design with ground wire when new aerial power lines are to be constructed

3. Provide stainless tube fiber unit with optimal protection

4. Conduct large fault short-circuit current and providing lightning protection

5. Suitable for application in hih fiber count and super high voltage power lines

6. Match with favorable tension-sag of the diffluent grond wire.

Application

Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance.

Fiber and Loose Tube Color Identification

The individual fiber and loose tubes shall accordance with standard TIA/EIA-598-A and the color code as below.

Steel tube 1 (No.1-12 fibers) : Single mode optical fiber (SM)

Fiber Colors

Steel tube 2 (No.13-24 fibers) : Single mode optical fiber (SM)

One black tracer (50mm pitch)

Steel tube 3 (No.25-36 fibers) : Single mode optical fiber (SM)

One black tracer (100mm pitch)

Steel tube 4 (No.37-48 fibers) : Single mode optical fiber (SM)
