　　Product Description:

　　OPGW optical cables can adopt aluminum tube type, aluminum skeleton type, and (stainless) steel tube type structures according to user needs. The optical fibers are sheathed in stainless steel sleeves, surrounded by aluminum clad steel wire (AS wire) and wrapped with aluminum alloy wire (AA wire) layers to form cables. When the first two structures of OPGW are subjected to short-circuit current impact, the aluminum tube and aluminum frame will generate relatively high temperatures and diffuse inward, thereby affecting fiber transmission and even fiber breakage, while the stainless steel tube type significantly improves the situation. If the structure contains aluminum, after exceeding 200 ℃, the aluminum will first undergo irreversible plastic deformation. At the same time as the structure is damaged, the increased sag of OPGW not only cannot maintain a safe distance from the conductor, but may also collide with the conductor. If it is an all steel structure, it can work at 300 ℃ for a short time.

　　Characteristics of OPGW optical cable products:

　　Combining the dual functions of ground wire and communication optical cable, it eliminates the huge cost of repeated installation and maintenance;

　　Installed on the top of the overhead power line tower, without considering factors such as hanging points and electrical corrosion

　　During the renovation process of the old line, the outer diameter and tensile strength of the optical cable can be better matched than another ground wire;

　　Large transmission capacity, high communication quality, and good reliability;

　　Has superior mechanical and electrical performance;

　　.

　　Product Features:

　　1. Small outer diameter, light weight, and no additional load on the tower.

　　2. The calculated fracture strength is high and can withstand the test of harsh environments.

　　3. Can accommodate 2-72 core single-mode/multi-mode optical fibers or a combination of single-mode and multi-mode optical fibers.

　　4. G.652 fiber optic, G.655 fiber optic, or a combination of both can be used.

　　5. Reasonable structural design to ensure that the optical fiber operates without strain under normal operating conditions

　　The optical fiber protection of the center tube OPGW power cable is placed in a sealed and waterproof stainless steel tube, which is placed at the center of the cable and twisted with one (or more) layers of single fibers on the outside; The layer twisted OPGW power fiber optic cable is protected inside a sealed and waterproof stainless steel tube, with an aluminum clad steel monofilament at the center. The stainless steel tube and monofilament are twisted in layers, and one (or more) layer of monofilament is twisted outside.

　　The central tube type can have a thicker single fiber diameter and a thinner outer diameter than the layer twisted OPGW. The layer twisted OPGW can be twisted to produce larger cable diameters, while the SFPOC can be twisted to produce 2 or 3 layers of OPGW. Meet the requirements of large span and large short-circuit current capacity. Because, so rest assured, welcome new and old customers to come and purchase.

　　The design of OPGW optical cable fully considers the actual situation of power lines and is applicable to any newly built high-voltage transmission line. We can carefully design matching products to meet the needs of users with different tensile strengths and short-circuit currents, in order to achieve a balance between mechanical and electrical performance.

　　The function of the pre twisted suspension clamp is similar to that of a regular suspension clamp, used for suspending conductors and ground wires on towers. The difference is that the pre twisted suspension clamp not only provides reliable ground protection for the wire, but its smooth outer contour greatly reduces corona discharge, making it particularly suitable for high-voltage (220KV and below) lines. In addition, the double pivot pre twisted suspension clamp can also be used on long-distance transmission lines crossing rivers and towers with large angles (30 ° -60 °). The pre twisted suspension clamp consists of a protective wire, an elastic synthetic rubber pad, a metal sheath, and other parts. The curved rubber pad is used to grip the suspension point of the wire, and the pre twisted protective wire is wrapped to protect and fix the wire, ensuring stable and reliable operation

　　Product composition:

　　Inner twisted wire, outer twisted wire, rubber clamp block, casing, right angle hanging ring, U-shaped hanging ring, bolt, nut, etc.

　　Product Features:

　　1. The stress distribution is uniform and there is no convergence point, which can enhance the stiffness of the cable installation point and provide good protection performance for the optical cable.

　　2. It has good dynamic stress bearing capacity, and the double-layer structure provides greater protection for optical cables under long-term unbalanced loads. Its grip strength can reach 10% to 20% of the ultimate tensile strength of the optical cable.

　　3. It has a large contact area with the optical cable and is equipped with flexible rubber clamps to enhance self damping and reduce wear.

　　4. The flat surface and smooth end shape increase the corona discharge voltage and reduce energy loss.

　　5. The standard aluminum alloy material improves the mechanical performance and corrosion resistance of the wire clamp, greatly extending its service life.
