  1. Eb-flex 2/0 welding cable review/comparison

    The structure of the cable for the welder is single wire core , usually composed of copper wires and copper wires . The group of copper wires make up the conductor part of the welding machine cable , so the YH cable is thicker and hundreds of copper wires . A plurality of groups of copper wires is wrapped around a layer of heat resistant polyester film . The insulation layer is pure natural rubber , the copper wire are oxygen free copper , so as to ensure the good conductivity of the wire core and the safety of the cable , these are the introduction to the welding cable products . If you buy an electric welding cable , you can go to the professional hardware market . But the quality of the hardware market is uneven , if not professional enough . It's quite possible to buy products of poor quality . Therefore , for professional products to find professional manufacturers . Where to buy welding cable by the foot?? Let me tell your the answer. Henan Central Plain Cables and Wires Co,.Ltd be a professional manufacturer of welding cable manufacturers found in 1993 , the production of welding cable more than 20 years of experience . We can produce PVC Welding Cable , Rubber Welding Cable ,EPDM Welding Cable , Battery Cable . All products are manufactured in strict accordance with the standard , welding line is particularly soft . All our specifications are in stock and ready to be shipped . Welcome to inquiry.
  2. Power cable is a kind of wire products transmitting electricity energy or electrical signals and transferring between electricity and magnetic energy. It’s always constituted by cable conductors to transmit electrical signals and sheathes to protect and insulate. Most of cable products are the shape of a long bar and have the definite same cross section, which is determined by their using characteristics, after all, they are usually took advantage of composing circuit in the electrical equipment. Therefore, we can only observe its cross sections when researching the structural components of wire products and analyze it utterly. From some specific sense, power cable manufacturing industry belongs to an industry that materials are finished machining and utmost assembled. There are some difficult standards to limit the development of the manufacturing industry, one of which is the huge quantities of metallic materials, definitely, their cost for materials takes up almost over 80 percent of total manufacturing costs. Second, the species and breeds of necessary materials are actually multiple and the performance requirement is absolutely high. Such as the common conductor copper, if used, it’s required to be nearly over 99.95 percent purity fineness. Cable conductors in car cables for battery are constituted by metallic materials with great conductive performance. The common conductors we use are two kinds, copper and aluminum. Now, we draw a comparison from their conductivity to help consumers to choose the suitable products. For the copper cable core, its electrical resistivity is 1.68 times lower than that made of aluminum and copper cable core also has better flexibility over 30 percent. Out of its low electrical resistivity, copper core has lower electric energy loss, which is beneficial to upgrade the plant factor and protect the environment. What’s more, compared to aluminum, when the two cable conductors have the same cross section, copper will be admitted more current-carrying electricity to pass, about 30 percent higher than the other. At normal status of temperature, compared to aluminum, copper has a higher intension more than 7 to 28 percent. Undoubtedly, the material of aluminum is prone to be fractured when it’s bucked again and again, but copper is not. About elastic index, aluminum is actually lower a lot than copper, even 1.7 to 1.8 times. Besides, copper has a better stability and it can avoid from being oxidized and corroded, and the aluminum easily breaks down. Utmost, the copper makes it more convenient to construct. Because of its flexibility, it will be easier to install the 2 gauge battery cable by the foot conductor in pipe. And its stability helps to connect wires more favorable. Besides, the greater mechanical strength copper has, the greater mechanical strain it can bear, as creates the preponderant conditions to mechanized construction. As for the cable core made of aluminum, whose price is much cheaper than copper, it’s suitable for some projects with low investment. Definitely, a kind of oxidation film will be produced when aluminum is exposed to air, which can be avoided from further chemical reaction. Therefore, aluminum conductor is widely used in high voltage, large cross section and large span overhead transmission. Nevertheless, despite the cheap cost of aluminum, copper power cable still has overwhelming advantages of the market of power supply, especially in the field of underground cable. After all, copper cable can furthest avoid accident and erosion, and it’s more convenient even reliable. Henan Central Plain Cables And Wires Co Ltd, has been professionally manufacturing the power cables for 34 years, adhering to the service aim that insist on quality first and serve consumers sincerely. We’ll provide high-quality products and service for everyone. Welcome to consult.
