What are the types of power cables?

Power cable is divided into: ADSS cable, OPGW cable, OPPC cable, OPLC cable.

1. ADSS cable is the abbreviation of Alldielectricself-supporting. All-dielectric refers to the all-dielectric material used in optical cables.

Self-supporting means that the reinforcing member of the optical cable itself can bear its own weight and external load. The name indicates the environment in which this cable is used and its key technologies: since it is self-supporting, its mechanical strength is very important;

The use of all-dielectric materials is because the optical cable is in a high-voltage and strong electric environment and must be able to withstand the influence of strong electricity; because it is used overhead on a power tower, there must be a matching pendant to fix the optical cable on the tower.

That is to say, ADSS cable has three key technologies: cable mechanical design. Determination of suspension points and selection and installation of supporting hardware.

2. OPGW optical fiber cable OpticalFiberCompositeovergroundWire (also known as optical fiber composite overhead ground wire).

The optical fiber is placed in the ground wire of the overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structural form has the dual functions of ground wire and communication, and is generally called OPGW optical cable.

3. OPPC optical cable (OPTical phase conductor, OPPC for short) is a new type of special optical cable for power communication systems. The power distribution network system avoids frequency resources. route coordination. The contradiction between electromagnetic compatibility and the outside world makes it have the dual functions of power transmission and communication.

3. OPLC fiber optic composite low-voltage cable or power fiber.

The optical fiber is combined in the structural layer of the power cable, and the cable with the functions of power transmission and optical fiber communication at the same time is called the optical fiber composite power cable. Like the optical fiber composite overhead ground wire (OPGW), the optical fiber composite power cable integrates two functions, which reduces the total cost of engineering construction investment and operation and maintenance, and has obvious technical and economic significance.

ZR Cable focuses on the research and development and sales of optical fiber communication products. Optical communication products include standard product optical cables, optical fiber jumpers Cables, mpo/mtp data centers, optical fiber distribution frames, etc., at ZR Cable you can buy all optical communication products in one stop.
