Long Distance Loose Tube OPGW Cable 24 Core Optical Power Ground Wire Optical Fiber Cable

OPGW optical cable combines optical fiber and copper wire (or other metal wire) together. It can transmit both optical signals and power. OPGW optical cable is suitable for long-distance communication transmission occasions. OPGW optical cable has low fiber transmission loss, which can ensure the stability and reliability of communication signals during long-distance transmission.

Inquiry

The outer layer of No.T-FC052 OPGW cable consists of a metallic conductor (usually aluminum or aluminum alloy). Which provides grounding protection for the power transmission system. In the OPGW cable assembly there are one or more optical fibers that help transmit data signals. Such as telecommunications and internet traffic. OPGW cables have good tensile strength. They are able to withstand the mechanical stress imposed on the cable by environmental factors. Such as wind and ice.

OPGW is primarily used in the power industry and is placed at the safest and highest point in the transmission line. OPGW in transmission lines is able to handle electrical faults on the transmission lines by providing a path to ground without damaging the sensitive optical fibers within the cable.

OPGW cable is one of the most composite cable and special optical cable designed to perform dual purposes. It is well able to carry high voltage electricity and transmit data through optical fibers embedded in the cable structure.

Feature

  1. Good insulation;
  2. Good corrosion resistance;
  3. Low optical fiber transmission loss;
  4. High strength and high tensile strength;
  5. Good flexibility, able to adapt to complex line layout and bending requirements.

Application

  1. Widely used in power transmission and distribution systems (especially high-voltage overhead power lines);
  2. Widely used in Telecommunications Network;
