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
- This is too difficult to give you a way to just try: with a fine wire rope, that is, lift the clothes on the stick so thick, the end of a bend, with a tape wrapped around the head, try can not wear, wear When the possibility of rotating wire rope, if you can go through the success of the half, the key is to use the wire through the more difficult, can only use the cord, hard-line 100% make life difficult.
- Q: What brand of cable is good, what are the top ten brands of wires?

- Q: What are the varieties of wire and cable (detailed point)
- Cable regardless of the definition of the number of elements in the definition of a few such as: YJV-3 * 50 + 1 * 16 calculated the number of lines is always a different, different wire rules Model input: bv-2 * 2.5 / bv-3 * 4 (different material), bv-2 * 2.5 + 3 * 4 (the same material)
- Q: Why does the bird stand on the wire without anything, but if people touch it,
- Is not the home of the bus box? Generally put a cat, a router, a power outlet, two transformers, the other is the network cable and telephone, the key space to be enough
- 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: What are the T and T, s of the wire and cable test type?
- The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.
- Q: What is the warranty period for wire and cable?
- Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.
