OPGW optical cable, namely optical fiber overhead composite ground wire. OPGW has the dual functions of communication information transmission and ground wire. OPGW optical cable is generally used for new lines and has low cost.
OPGW optical cables are divided into: aluminum tube type, aluminum skeleton type and (stainless) steel tube type structure. The optical fiber is inserted into a casing made of stainless steel, and the casing is surrounded by aluminum clad steel wire (AS), and the outer layer is wrapped with aluminum alloy wire (AA), and then twisted into a cable. Hunan Zhanlian Optoelectronics can design OPGW optical cable specifications according to customer requirements, with 4-48 cores and a cross-sectional area of 40-150.
1、Using advanced stainless steel tube production technology, the tube is filled with water-blocking compounds to protect the optical fiber;
2、Good compact structure and high tensile strength;
3、The short-circuit current has little mutual interference between the power grid and the communication network;
4、The excess length of the optical fiber and the cable core twisting pitch of the OPGW optical cable are not subject to stress when the operating tension is large;
5、Similar to the specifications of the commonly used ground wire, it is very convenient to install and can directly replace the original ground wire.
In today’s high-tech world, with a strong reliance on a robust and highly reliable telecommunication infrastructure, new technologies have emerged to support easy and efficient growth now and in the future. One such technological advancement is the Optical Ground Wire (OPGW). This fiber optic cable is designed to be installed on transmission and distribution lines and protects the optical fiber from environmental conditions (lightning, short circuits, loads) to ensure reliability and longevity. This article can help you learn more about OPGW cables.
