Optical Ground Wire (OPGW or OPTGW) is a dual functioning cable that performs the duties of a ground wire - also known as static wire - while providing a path for the transmission of voice, video or data signals by incorporating optical fibers into the design of the cable. The sheath binds the inner wires together, and its outer markings indicate the number of wires and size, or gauge (AWG), of wire within the sheathing. When required, a larger central wire (king-wire) is included in a conductor. 5 wireholder is standard equipment or the 2. China 500kv Power Transmission Line Angle Steel Tower 500Kv Power Transmission Line Angle Steel Tower Jiangsu Mingyuan Tower Co. • Suitable for hot line installation. GB standards are the China national standards; Prefix code GB are Mandatory standards, GB/T are Recommended standards; All products or service must be compliance with GB standards. OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current or provision of anti-lightning protection. 11 by Doug Proctor June 14, 2005 IEEE Guide P524 to the Installation of Overhead Transmission Conductors. Participants will learn how conductor motion, such as galloping and sleet jump affects reliability. Corona is the electrical ionization of the air that occurs near the surface of the energized conductor and suspension hardware due to very high electric field strength. 2 As an European high-tech company nkt cables develops and manufactures innovative power cables and accesso-ries, fiber optic ground wires (OPGW) and fiber optic phase. Find business, photos, videos, products, services, branches, maps and contact information for power systems - Yellow Pages PH. The OPGW conductor is usually composed of a central non-metallic tubular structure containing optical fibres, situated inside the steel or electro-welded tube. ADSS Cabling is offered in different sizes starting from the standard size, mini-span, flat drop and aerial drop solutions. Our organization is counted amongst the most distinguished manufacturers Wire Mesh Socks for OPGW. Fork-type, 1. for wires bigger than 16 sqmm and lower than 35 sqmm, the earth wire must be 16 sqmm. The OPGW conductor is usually composed of a central non metallic member containing the fibres, which is situated inside the steel or electro-welded tube. Frame is made of aluminium alloy to save weight. 3 m sample of OPGW shall be tested. The core maybe single wire or stranded depending on the size. ) , With over 30 years production experience and 15 years export experience, factory price without any third party. ZTT Technology is the biggest OPGW manufacturer in China. Manufacturer of OPGW Tools, Railway Electrification Tools & Stringing Tools for Transmission Construction offered by Techo Scient Manufacturing Company from New Delhi, Delhi, India. Size (AWG or KCM) STR (AL/STL) Diameter (Inches) Wt. Accessories and Fittings: Ground wire assemblies and fittings may be included in. OPGW Cable, Optical Fiber Composite Overhead Ground Wire, also known as Fiber Composite Overhead line. Assumptions: Aluminum Conductor Steel Reinforced (ACSR), Tubular (230 kV)/ Lattice (345 kV - 600 kV), > 10 miles In addition, Black & Veatch developed capital cost estimates for the 600 kV HVDC voltage class. Optical Ground Wire (OPGW or OPTGW) is a dual functioning cable that performs the duties of a ground wire - also known as static wire - while providing a path for the transmission of voice, video or data signals by incorporating optical fibers into the design of the cable. Example of usage: 19/0. Characteristics OPGW is categorized as loose buffer-type OPGW made by containing optical fibers in a plastic tube and SSLT-type OPGW made by containing optical fiber in a stainless steel tube, depending on the structure of the optical fiber unit that wraps the optical fiber. 5 Auxiliary components Use swivels that are specifically designed for OPGW cables. Generally the composition of insulator hardware shall be of that specified in the drawings, but not limited thereto, and the ultimate strength of the hardware for double suspension and tension insulator strings shall be not less than 240 kN and for single suspension and tension string not less than 120 kN. (SEI) in 1897 with copper wire production, we have developed many new technologies and products through innovative R&D activities based on SEI's manufacturing expertise for electric wires and power cables. Not only production. d e t a il 3 a d d e d. Overhead Conductor Installation Guide Recommended Practices Firs dition 3. These cables are suitable in areas with high humidity and in places with high air pollution. 5% aluminum ensuring with this purity a high resistance to corrosion. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of transmission for large quantities of electric power. OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. With over 30 years production experience and 15 years export experience, factory price without any third party. About 42% of these are power cables, 16% are electrical wires. 40 mm Total solid elements = 234,119Inner wires face element size = 0. The minimum diameter of the reels (where the OPGW is to be coiled) used during the installation should be at least 80 times the diameter of the OPGW cable. OPGW Cable Specifications Bid No: Cable Type: OPGW-8B1-91 [70. Corona and its Effects Evan Mayerhoff High Voltage Connection, Inc. The core maybe single wire or stranded depending on the size. Protect the cable and conductor from fricting when they are laying. Professional OPGW Wire manufacturer from China, Meet your kinds of requirement OPGW cable. They are built to industry specifications and include a grade number based on the conductor size they are designed for.
