Brand: RRT Tianrun a boat models: OPGW fiber count: 24 Cable diameter: 10-28 (mm) Weight: 200-450 (kg / km) allows tensile strength: 1500 (N) allows lateral pressure: 2200 ( N / 100mm) Scope: power cable, ground cable, optical composite short-circuit current capacity: 8.9--149 cable types: special cable Operating Temperature: -40 ~ + 80 cable Introduction: OPGW cable, also known as fiber composite overhead ground fiber optic cable to be placed in an overhead high-voltage power lines in the ground, in order to constitute a transmission line of optical fiber communication network, which forms the structure of both the ground and the dual function of communication, commonly referred to as OPGW cable. Since the optical fiber with anti-electromagnetic interference, light weight and other characteristics, it can be installed on top of the transmission line towers without having to consider the best frame hanging position and electromagnetic corrosion problems. Thus, OPGW with high reliability, superior mechanical properties, lower cost and other notable features. This technique when newly installed or replaced existing ground particularly suitable and economical. Fiber is the use of the core and cladding refractive index difference between the size of the two materials to make light in optical fiber transmission, which became a major revolution in communications history. Fiber optic cable light weight, small size, the power system has been adopted, the transfer between the substation and dispatch telephone center scheduling, remote signal, relay, television images and other information. In order to improve the stability and reliability of fiber optic cable, fiber optic cable and foreign development phase conductor transmission lines, power cables and composite overhead ground as one of the structures. OPGW cable due to the metal wire wrapped, so that the cable is more reliable, stable, strong, due to the composite overhead ground wire and cable as a whole, compared with other forms of fiber optic cable, both to shorten the construction period and save construction costs. In addition, if the aluminum-clad steel wire or aluminum wire stranding of OPGW, equivalent to erect a good conductor of the overhead ground wire, you can receive reducing power lines arc current, lower power frequency overvoltage, improve power line communication lines multiple benefits of interference and dangerous impact. Beijing OPGW-24B1 designated key national cable network manufacturers | Beijing OPGW overhead power cable price My company specializes in producing fiber optic cable / cable, OPGW / ADSS power cable, GYTA / GYXTW outdoor cable, MGTSV / GYTA53-333 / GJPFJV mine / underwater / indoor fiber optic cable and weak series / security defense / PV cable / video cable / household wiring / special cable / optical composite cable, such as a full range of fiber optic cable manufacturers, the country in Beijing (Headquarters) / Shanghai / Dalian / Shenzhen / Henan / Yangzhou / Chengdu has a large factories and cities can be shipped nationwide, more convenient and more efficient for your service, welcome to inquire stainless steel tube stainless steel tube OPGW OPGW cable stranded stainless steel tube structure, coloring fiber sheath seamless steel pipe into the sealed inner tube filled with water blocking compound containing fiber stainless steel tube with aluminum clad steel wire Stranding core cable core and then a layer of aluminum-clad steel stranded wire or aluminum wire, this OPGW cable because of a simple structure, high tensile strength and special characteristics of short-circuit current statistics, but for a variety of new power lines and power lines have been built alterations, the main features of the product are: ① the use of advanced stainless steel production technology, tube filled with water blocking compound to effectively protect the optical fiber. ② through a stainless steel tube into the cable fiber excess length and optimal design stranding pitch, so that the fiber optic cable length quadratic residue obtained to ensure that the subject of OPGW fiber tension is not running at maximum power. ③ compact, good, not only reduces the ice load and wind load, but also to determine the heat generated in the case of short and easy to disperse. OPGW cable type aluminum tubes type of OPGW cable core layer using twisted structure, multi-fiber loose tube cable after a cladding layer seamless tubes as fiber metal protection tube, twisted metal and then a layer of protection tube or multi-layer aluminum or aluminum-clad steel wire, with the advantages of the product in addition to stainless steel tubular OPGW cable, but also have the following advantages: ① seamless tubes homogeneous, with the entire ground material coordinated aluminum clad steel wire, No worry electrochemical corrosion. ② due to uniform material and structure of the whole earth, so better fatigue resistance properties. Mechanical properties of OPGW 1.OPGW on the ground should have compatibility, namely OPGW diameter, weight and mechanical characteristics compatible with the original ground to ensure that at WIND, Dutch ice conditions are safe and reliable operation. 2. Ensure OPGW has a high mechanical strength, so that within the allowable tension range, the fiber will not stretch and tension OPGW, affect the life, which increases losses. 3. has good thermal stability. The main application of OPGW on 500KV, 220KV, 110KV voltage line use, the impact of power lines, security and other factors, multi-application on the new line. OPGW applicable characteristics are: (1) high pressure over 110kv line, span large (generally in more than 250M); (2) easy to maintain, easy to solve the problem for a line across its line of mechanical properties can meet big leap; ( 3) OPGW outer layer of metal armor, no corrosion and degradation of the high-voltage; (4) OPGW in the construction must be power outages, large power loss, so the new 110kv high voltage line above should be used in OPGW; Beijing OPGW- 24B1 designated key national cable network manufacturers | Beijing OPGW overhead power cable prices
