Basic wire and cable knowledge The manufacturing of wire and cable is completely different from that of most mechanical and electrical products. Mechanical and Electrical Products are usually assembled into parts, multiple parts are installed into a single product, the product is measured in the number of units or pie

and small four-core insulated wire cores into three insulated wire cores with smaller cross-section, and symmetric the three core Cables into cables, for 6/10 kV Inverter Motor cables, the cable structure is different from that of 6/10 kV common power cables. The common power cables shield three insulated wire cores w

The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pa

Since the beginning of this winter, many regions in China have suffered a cold wave. Since March November, China's North suffered a blizzard, which brought significant losses and impacts to the national economy and people's lives. On December 24, the Central Meteorological Observatory issued an orange cold wave alarm, which said that from the 24 th to the 26 th, a strong cold air would once again attack northern, western, and some eastern parts of China. This indicates that the "Frozen" phenomen

For example, 120 mm² calculation: 120*8.89 = 1066.8 kg/km 1 conductor usage: (Kg/Km) = d ^ 2*0.7854 * G * N * K1 * K2 * C D = copper wire diameter G = copper proportion N = bars K1 = copper wire twisting rate K2 = core wire twisting rate C = insulation core wire number 2 insulation usage: (Kg/Km) = (D ^ 2-d ^ 2) * 0.78

line sequence of the wire head Now the most widely circulated, is the 100M wire Head card method. The cable head with the card side facing down, there is the end of the copper piece outward, starting from the left count, divided into 12345678. Orange white, orange, blue white, green, green white, blue, brown white, brown. This is the standard line order of the
