Carbonfiber composite core conductors(hereafter called CFCC for short) consists of composite core and annealedaluminum formed wires outer layer. Theannealed aluminum formed wiresouter layer and its adjacent layer aretrapezoidal cross-section. CFCC is a kind of carbon fiber product with highperformance. Compared with the traditional aluminum conductorssteels-reinforced(hereafter called ACSR for short), it has series of advantagesincluding light weight, high tensile strength, high heat resistance, corrosionresistance, high current carrying capacity etc.
Inthe case of the same weight, CFCC has higher current carrying capacity, whichwill be twice of the conventional ACSR. The annealed aluminum formed wireswhich has less line loss is used in CFCC. Moreover, Composite core isnon-magnetic material, so it does not have magnetic loss and thermal effectscaused by the steel wire material. It will greatly reduce the line transmissionloss. CFCC can improve the current carrying capacity under high temperaturesince its heat resistance (can be 160 ℃ aslong-term running temperature) is far more higher than that of the ACSR (70℃ as themax operating temperature). On the other hand, CFCC has light weight. So in thecase of the same weight, cross-section of aluminum can be increase by 20%-40%.Therefore Reerecting the new CFCC line for increasing transmissioncapacitywithout transforming the poles and towers became possible.
CFCChas the higher strength and higher level of safety. The tensile strength of theACSR is 1240MPa, and high strength steel conductors is 1410MPa; however CFCCcan be up to 2400MPa which increases the safety.
Itwill reduce the transmission line corridor, save land resources and lower thecomprehensive total cost of transmission line construction by using CFCC. CFCC’s linear expansion coefficient is small, and it reduces the lines sag, andwill not be affected by long-term creep of aluminum, also it avoids sag due tothe thermal expansion of the traditional ACSR. The height of the tower can bereduced, and the distance between towers can be increased due to its lightweight. More than 16% poles and towers will be reduced to save the transmissionspace height and areas.
CFCChas good anti-aging performance and long operating life. it avoids the troublethat the ACSR’ electrochemical corrosionbetween the aluminum and galvanized steel core. compared with the ACSR, CFCCresist acid rain corrosion.
CFCChas good resistance to wind load .with its high strength, light weight, crosssection covered by aluminum formed wire, small diameter.
CFCChave the ability of melting snow and ice. The outer layer has no gaps and iscompacted smoothly. Snow and ice is not easy to be freezed. The conductor willmelt snow and ice by itself When it is running under high temperature also.
CFCChas high current carrying capacity to reducing electricity generationcost and saving energy. It will reduce the line loss by 28% in the case of sametransmission capacity.
CFCCrepresent the technical development tide of overhead conductors. It has obviouseconomic and social benefits. it conduce to building safe,environmentally-friendly, efficient electricity grid.
- Q: Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More
- Bookstore tool book should have "communication project budget", I do is what you say, the budget is divided into estimates and budget, is two steps. So that is not very clear. But what is needed is the preliminary design of the project. The budget is needed for design and drawings. Internal management of this piece, the main thing is that you need to do what the project department, and are generally very complicated
- Q: Apple 6splus charge may not support this accessories how to do more
- Sometimes no way, the problem to the owners to solve the common, must wear, the owners agreed
- Q: How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more
- According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
- Q: Wire and cable CCC product consistency is what
- PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.
- Q: Apple 6 Charging Why always show this cable has not yet been certified
- And I answered the other person's question is very similar: . the line of the banding distance of not more than 1.2 meters, the two ends of the wire box outlet tube 15CM should be ligation; . casing embedded, then through the basement wall, the surface must be installed rigid Waterproof casing, that is, steel pipe + water ring; through the fire pool, living pool: flexible waterproof casing; (wing ring specific practices can be collected online related Atlas); through the floor, according to whether the design requirements , Under normal circumstances PVC casing on it. Note: . rigid waterproof casing, flexible waterproof casing is a one-time reserved in place, through the floor of the casing of the flower lamb to suppress the barge of Xi Jie Xi Xi shou, is the first stay hole, when the installation of riser Casing, because the floor casing has every layer, the location of the reservation will always be biased, in order to ensure vertical vertical pipe, and finally unified hanging line repair hole and then install the riser and casing. . now most of the bathroom are dirty, waste and diversion, and more of the riser, and so on, the air conditioning casing of all the shear wall should be embedded, to avoid the subsequent damage to the structure of drilling (no stay can only drill) Note that the location of the hole and the installation of the riser will affect the opening of the toilet window. . the casing is the casing, riser is the riser, casing than the riser model 1 to 2 level. . plate at the end of flat, board 2 to 5CM higher to see if you need to do leveling layer.
- Q: What is the difference between the WDZ wire and cable, the ZR wire cable and the NH wire and cable, and what kind of wire and cable should be used?
- Make a mark, such as red set into the bottom for a color in a layer, or you can draw a few plans, water and electricity is a strong power is a weak and one, the label can do a good job
- Q: Why does the bird stand on the wire without anything, but if people touch it,
- National standard line, no problem. Do not pick up the heater in winter. If not the national standard line, that copper is not easy to go wrong, then use, from time to time touch the line is not hot, there is no problem.
- Q: How are various wire and cable models named?
- Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.
- Q: If you want to sell wire and cable, then what to do in advance to detect? The The The The The
- To be considered is the Great Wall power line is not long enough, the power is not big enough to see the power on the label, if the 12V to 15A or more I think will be more stable, my Dell machine power cord surprisingly short, but also To buy the extension line again.
- Q: What are the T and T, s of the wire and cable test type?
- You should be said: 2-way cross-linked polyethylene insulated PVC sheathed cable 4 core 185 square millimeters, SC is steel pipe, diameter . FC is laying method dark cover the floor or floor. Personal opinion, hope to help you!
