What is the DDF rack? what's the effect?
Therefore, the "wire" and "cable" does not have a strict sense of the distinction and definition "Wire", generally refers to the wrapped insulation of the wire products, "magnetic wire" and "universal insulated wire" of the points "Electromagnetic wire" refers specifically to the production of coils or windings of the "enameled wire", "universal insulated wire" refers to the one or more wire from the glue, the outsourcing of plastic, rubber and other insulation material, mainly as transmission power and signal Connection "Cable", by one or more shares of insulated wires placed in the sealed protective layer, for the transmission of electrical energy and signal At present, in the original traditional rubber, lead-based cable on the basis of new plastic cables and other new products Newly used low-voltage distribution lines in rural areas have a single insulated wire and "bundled wire", a single insulated wire is in the original bare wire on the basis of outsourcing insulation plastic layer, mainly to reduce the typhoon, snow, bamboo and other power lines "Bundled wire" is the new wire in recent years to be promoted and applied, in addition to insulated wire function, the "cluster wire" the biggest advantage is to reduce the channel's channel occupancy and to prevent external theft, Beautify the rural visual environment However, in recent years, with the need of power communication, "fiber optic cable" came into being, the power cable entrained optical fiber communication cable has become the main direction of the future development of power cables At present, this kind of photoelectric single cable, mainly used for submarine cable and for the user terminal line, easy to achieve in the power transmission at the same time to achieve communication synchronization for the future development of intelligent power grid to bring the convenience of information transmission
However, with the modernization of power transmission equipment and information needs of social development, and now the wires and cables have been developed to the "cable in the cable", "cable in the cable" era
Hello: "Wires" and "cable" in the concept and there is no strict distinction between the boundaries, although the narrow sense of "wire" and "cable", said broadly should be collectively referred to as "cable" The Generally known as a single called "line", more than called "cable"; small diameter called "line", the structure of complex multi-called "cable"
