Description :
Product Name: OPGW Optical Cable (also known as Fiber Optic Composite Overhead Ground Wire)
Product brand: Changguang Communication Co., Ltd
Product types: There are three main categories: aluminum tube type, aluminum frame type, and (stainless) steel tube type.
Performance characteristics: Aluminum clad steel has the advantages of high strength, good corrosion resistance, and superior electrical performance compared to galvanized steel wire. Due to the many combinations of aluminum layer thickness and steel wire strength, it has great design flexibility.
Performance: Aluminum clad steel wire is commonly used in overhead power line products, including wire reinforcement cores, ground wires, transmission lines, etc. It can also be used as load-bearing cables or guy wires
Installation of OPGW supporting fittings and accessories
After tightening the OPGW optical cable within a tension section, accessory installation should be carried out promptly. OPGW adopts pre twisted wire fittings components, which are basically the same as those used for ADSS optical cables. They generally include: tension clamps, suspension clamps, dedicated grounding wires, shock hammers, protective wires, down conductors, intermediate splice boxes, terminal boxes, tail fibers, etc. The installation method is detailed in the manufacturer's instructions.
Tension clamps: generally used on terminal towers, towers with angles greater than 15 degrees, or towers with large height differences, with two sets per tower.
Suspension clamp: Hang the optical cable on a straight tower to provide support, with one set for each straight tower.
Anti vibration hammer: It is used to reduce wind vibration, protect OPGW fittings, and extend the service life of OPGW. It is placed on both sides of the tension and suspension fittings of each tower, and the number of configurations and hanging points are determined according to the line conditions; PVC spiral shock absorbers are widely used in Europe and America, and there are already test sections in China with good anti vibration effects.
Downlead clamp: It is mainly used to fasten the OPGW that is led down or up from the tower to the tower, preventing it from shaking and avoiding wear on the outer armor of the optical cable. It is usually done every 1. 5-2M with one fixture.
Special grounding wire: provides a path for short-circuit current when the system is grounded. It is twisted with aluminum wire to a certain length and should have good contact with metal fittings and iron towers. It is usually matched with tension and suspension fittings.
