pure copper wire refers to the cable core is made of copper, national standard wire refers to the cable in accordance with national standards, they do not say the same thing, so can not directly answer your question; Whether the cable conforms to the national standard, in addition to the common standard requirements, the cross-sectional area of the cable to comply with the standard specifications, but also based on the following criteria to determine whether to meet the standard: 1. Appearance standard, cable must have certification mark, manufacturer, diameter, etc., ground wire with yellowish-green insulating layer 2. Mechanical strength 3. Sheath insulation (generally greater than 100m Ω) and voltage strength less than 500V (1500V) 4. Linear resistance (a certain diameter, conductivity, length not greater than a certain resistance) 5. High temperature shock 150 degrees, low temperature-30 degrees wire must not crack, etc. The national standard line of pure copper is the best.According to wire conductor materials, copper is the most widely used conductor material production is relatively cheap. The advantage is that the resistivity is small easy to process the full frequency conduction balance. The disadvantage is that common copper impurities are generally stable. Silver is a high-quality medium for small prices. The advantage is that the low resistivity and high frequency signal conduction is superior to the low frequency signal conduction. The drawback is that it is not easy to process and has poor stability. Alloys generally have copper silver plating, copper coated silver, copper silver tin, copper silver gold and other alloys. The advantage is stability good personality can play a variety of metal advantages. The disadvantage is that it is difficult to process. Carbon fiber is a new conductor material, small in production and expensive in price. The advantage is the environmental protection, the stability is very good individuality bright. The disadvantage is that the resistivity is slightly larger and is not easily machined.
now all the wires on the market are copper core wires, far more than the aluminum core wire, copper wire market share is so high, the following said the use of copper core wire characteristics. 1, high strength: the allowable stress at room temperature, copper is higher than aluminum by 7 / 28 respectively. Especially the stress at high temperature, the difference between the two is very far. 2, anti-fatigue: aluminum is easy to break after repeated bending, copper is not easy. In terms of elastic index, copper is also about 1.7 ~ 1.8 times higher than aluminum. 3, good stability, corrosion resistance: copper core oxidation resistance, corrosion resistance, while aluminum core is vulnerable to oxidation and corrosion. 4, large current: because of the low resistivity, the copper core wire with the same section is about 30% higher than the aluminum core wire. 5, low resistivity: the resistivity of aluminum core wire is about 1.68 times higher than that of copper core wire. 6, good ductility: the elongation rate of copper alloy is 20% 40%, that of electrical copper is more than 30%, and that of aluminum alloy is only 18%. 7. Construction convenience: 1 copper core is flexible, the allowable bend radius is small, so it is convenient to turn around, it is easy to wear pipe to resist fatigue of copper core, and repeated bending is not easy to break, so the convenient connection of copper core is higher than the mechanical strength of copper core. It can bear large mechanical tension, bring great convenience to construction laying, and also create conditions for mechanized construction. 8, low heating temperature: at the same current, the same section of copper wires have much less heat than aluminum wires, making it safer to operate. Low voltage loss: because of the low resistivity of the copper core wire, the same cross section flow through the same current. The voltage drop of copper core wire is small. Anti-oxidation, corrosion resistance: copper core wire connector performance stability, not due to oxidation accident. The joint instability of aluminum core wire often causes the contact resistance to increase and heat up due to oxidation. As a result, the accident rate is much larger than the copper core wire. 11, low energy consumption: because of the low resistivity of copper, copper wires have lower power loss than aluminum wires, which is obvious. This is conducive to increasing the utilization rate of electricity generation and protecting the environment.
TPC electrolyzed copper 2N OFC oxygen free copper (LC-OFC) grown and crystallized, oxygen free copper 4N-6NOCC single crystal oxygen free copper, perfect function copper, solid smooth copper, high purity solid smooth copper, wire structure. The small parallel strike signal lines with positive and negative conductors of parallel structure are arranged horizontally by passive shielding and are mostly used in the simple structure of common wire to produce mechanical strength difference and poor vibration absorption effect. The small signal lines of helical twisted arrangement of conductor with twisted core structure basically adopt passive shielding, and most of them are used in sound wire structure simple and easy to produce the actual length of wire is larger than the mechanical strength of finished wire length. Increasing the vibration absorber can also counteract some of the low frequency signal strings
choke coil is a common mode interference suppression device with ferrite as magnetic core. It is symmetrically wound on the same ferrite ring core by two coils of the same size and turn number, forming a four-terminal device. The large inductance of common mode signal is inhibited, but the leakage inductance of differential mode signal is very small. The choke coil can effectively suppress common-mode interference (such as lightning interference) in balanced line, but has no effect on the normal transmission of differential mode signal. The choke coil should meet the following requirements: 1) the wires wound on the coil core should be insulated each other to ensure that there is no breakdown and short circuit between turns of the coil under the action of instantaneous overvoltage. 2) when the coil flows through the instantaneous high current, the core does not appear saturated. 3) the magnetic core in the coil should be insulated from the coil to prevent the breakdown between the two under the action of instantaneous overvoltage. 4) the coil should be wound in a single layer as much as possible, which can reduce the parasitic capacitance of the coil and enhance the ability of the coil to grant the instantaneous overvoltage.
