Technical characteristics of iron triangle heating wire rod
Audio Technica uses a special high OFC copper wire material in its heating wire, which is made of OFC oxygen-free copper. Because the crystal arrangement in oxygen-free copper is irregular, the conductivity is reduced. Hi-OFC, on the other hand, adopts special metallurgical processing rules, so that the crystals in oxygen-free copper are arranged neatly and the electron circulation is smoother, so the conductivity is greatly improved. High-purity copper wires used in iron triangle are OFC, Hi-OFC and PC OCC according to different grades and uses. Although these three kinds of copper materials are graded in the performance of conductive characteristics, they are all excellent conductive materials. The iron triangle is special in the way of using these three conductive materials. Different from the fact that most wires only use a single conductive material, it uses a mixture of multiple conductive materials to capture the advantages of different wire materials and obtain a more balanced and accurate transmission effect.
For example, Tie Triangle newly launched DVD Link series signal lines (***6 models, including AT-DV33V video color difference signal line, AT-DV38S video special S-end signal line, AT-DV66A audio special 5. 1 channel signal line, AT-DV95D audio special digital coaxial signal line, etc. ), the main conductor in the signal line is PC OCC, and the outer braided shielding wire is Hi-OFC. The original factory said that PC OCC line is beneficial to low frequency transmission, while Hi-OFC is good at medium and high frequency transmission. The advantage of the combination of the two is that the signal line transmission bandwidth can reach 100MHz, which is very suitable for DVD and DTV digital TV which will be commercialized soon.

Technical characteristics of acoustic heating wire rod
The signal wires of American Audio Quest Company all adopt the geometric structure of HYperlitz multi-strand litz wires, which can eliminate the mutual interference and skin effect between wire cores. The sheath is made of polypropylene or PTFE insulation material, and its low capacitance can effectively prevent high frequency loss. There are 10 digital lines and video signal lines. Its Video One video cable adopts Teflon insulation sheath, silver-plated long grain copper (SP-LGC) conductor and silver-plated coaxial plug, which has a very wide passband. The Video Pro color-difference video cable is composed of HCF rigid foam plastic as insulation sheath and FPS solid silver wire as conductor, and its structure is similar to SP-LGC. However, the wire used in S-Video signal line of S-line series is four times thicker than that of ordinary S-Video signal line, and its length is also relatively short. For example, S- 1 adopts HCF insulation sheath and silver-plated long copper as conductor, which is symmetrically combined; S- 1 consists of two 75 ohm cables, one for transmitting luminance signal and the other for transmitting chrominance signal. Each cable is symmetrically designed. Besides the metal foil and braided shielding net, the other SP-LGC copper wire is used for grounding. The AC- 12 AC power cord of Xiansheng is the only power cord constructed by Hyperlitz in the market at present. The wire core adopts OFHC oxygen-free high conductivity copper, UL PVC insulation sheath and RF filter with iron powder core. Hyperlitz series speaker cable adopts Hyperlitz wire-making technology, which not only maintains the low skin effect characteristics of Ritz wire, but also has better ability to avoid multi-core wire distortion than Ritz wire, accurate music signal transmission and beautiful timbre.
Technical characteristics of sensitive line
Monitoring cables have a long history in Germany. The signal lines and speaker lines produced by it can be divided into two categories: standard series and best series. Conductor materials from multi-strand oxygen-free copper to silver-plated products are all produced by ourselves. The technical features of the sensitive wire include: MSR magnetic current reflection belt technology, TDC time difference control technology, Teflon insulation sheath, special ferrite core to prevent interference, and radium-plated lockable XLR plug.

Symmetrical response is equipped with Teflon insulator coaxial plug, and the thread end is equipped with ferrite core to prevent interference.
The 0097 1 130 in Acura series speaker cable adopts black sheath, symmetrical and balanced design of red and white wires (each 3 meters long), high-purity PC OCC oxygen-free copper wire core, unique TDC time difference control technology, gold-plated plug and banana plug. Its sound quality and performance accuracy reached a higher level at the same time.
Technical characteristics of eternal heating wire rod
Tara Laboratories is a famous manufacturer of heating wires. Tara Labs believes that an excellent audio product can only be obtained if subjective audition and objective test are coordinated. Therefore, the heating wire in Tara Labs is produced after digital equation calculation, accurate testing and extensive human hearing, which can ensure its excellent performance and adaptability to any type of audio system. There are three principles in the design philosophy of time and space: first, a simple design is a good design; Second, the product should be able to accurately play back music; Third, products should have better performance and more reasonable price. The copper selected for hyperspace is mined from a copper mine in Australia, which is one of the three highest known copper mines in the world. Pure copper conductor is further softened by a unique annealing step to improve its conductivity.
As for the dielectric, the material used in hyperspace is unique aviation grade polyethylene. Because of chemical treatment, it has low dielectric absorption rate, high dielectric tolerance and good elasticity. Compared with other dielectrics, aviation grade polyethylene can be extruded at a much lower temperature than PTFE, so the pure copper wire wrapped by it can maintain its special annealing properties. The conductor of hyperspace heating wire has a special diameter and thickness, so when the signal flows, it has the minimum DC resistance and attenuation below 20KHz due to skin effect. This optimal diameter and thickness are calculated by the unique mathematical equation of hyperspace, and then they can use the known material resistance and the higher frequency of conductor linearity to determine the optimal diameter and thickness of conductor made of any material.
In addition, hyperspace also cooperated with NASA to obtain the exclusive right to use and sell consonant alloy materials. According to related experiments, the electrical conductivity of Harmony alloy is higher than that of most heating wires on the market today, and its electrical conductivity is higher than that of 8N pure copper, which greatly improves the air sense, ultra-low frequency, sound stage and positioning of sound. Therefore, the space-time harmony alloy is used in the RSC square-core copper-based heating line, which makes the RSC square-core copper-based heating line with its own effect reach its peak.
Technical characteristics of Fan Denghao heating wire rod
Van Den Hul's heating wire in the Netherlands, one of the most talked-about sayings is that it is made of nonmetallic carbon fiber, but it is also made of copper and silver. Let's take a look at the technical characteristics of Fan Denghao's fever line.
According to Fan's technical research for many years, it is considered that there is transgranular distortion (CCD) in metal wires. Most metals are composed of a large number of grains, the grain size is about 0. 1- 1 mm, and each grain is single crystal. The molecules and atoms in the grains are arranged regularly, but the size and shape of each grain are different and the orientation is disordered, so this crystal has no obvious shape and does not show anisotropy, so it is called polycrystalline. So many different crystals are gathered together, and the number is huge. When the audio signal is transmitted through one of its metal wires, from a microscopic point of view, the audio signal "jumps" between crystals, and the crystals are different in size. Such interface transmission produces the distortion of CCD cross crystal. CCD is easy to produce "false overtones" to reproduce the false sound effect of "smoothing details".
In order to eliminate the crystal distortion of the metal conductor as much as possible, Fan Denghao added a metal sheath to the pure metal conductor through machining. For example, a pure copper conductor is covered with a silver or gold sheath, and then covered with an insulating sheath to isolate electromagnetic interference and prevent vibration. Another method is to spray a layer of gold film or silver film on pure copper wire in vacuum, which is adopted by Vandenhau's SCS series line. Van den Howe wire rod adopts a high-quality PVC material-Hull IFLEX, which is a brand-new environmental protection material, which can further prevent the influence of chemistry and temperature, and has good insulation and sealing performance. Its mechanical strength is three times that of conventional PVC, but its softness is better than that of traditional plastics. Therefore, chaff material has the advantages of stable chemical properties and long service life.
