The do's and don'ts of wire and cable, these you can't afford not to know!

Wire and cable industry is only a supporting industry, it is a large variety of products, a wide range of applications, involving electric power, construction, communications, manufacturing and other industries, and various sectors of the national economy are closely related. Wire and cable is also known as the national economy's "arteries" and "nerves", is the transmission of electricity, transmission of information and manufacturing a variety of motors, instruments, meters, electromagnetic energy conversion indispensable basic equipment, is the future of electrification, informatization of the society in the necessary It is the basic equipment indispensable for the realization of electromagnetic energy conversion, and is a necessary product in the future electrification and information society. So, does anyone know how to select wire and cable, what precautions? Wire and cable model selection: selection of wire and cable, to consider the use, laying conditions and safety. For example: according to the different uses, you can choose power cables, overhead insulated cables, control cables, etc.; according to the different laying conditions, you can choose the general plastic insulated cables, steel tape armored cables, steel wire armored cables, anticorrosive cables, etc.; according to the security requirements, you can choose not to extend the ignition of the cable, flame-retardant cables, halogen-free flame-retardant cables, fire-resistant cables and so on. Wire and cable transportation and storage: 1, the transportation is strictly prohibited from throwing down the cable or cable tray with cable, especially at lower temperatures (generally about 5 ℃ and below), throw, drop the cable will likely lead to insulation, sheath cracking. 2, as far as possible to avoid storing cables in the open air in the form of bare cable tray is not allowed to be placed on the flat. 3, lifting the packaging, is prohibited for several trays at the same time. In vehicles, ships and other means of transportation, the cable tray should be fixed in a suitable way to prevent each other from colliding or tipping to prevent mechanical damage to the cable. 4, the cable is strictly prohibited with acid, alkali and mineral oil contact, to be stored in isolation from these corrosive substances. Storage of cables in the warehouse shall not damage the insulation and corrosion of the metal of the presence of harmful gases.5, cable in storage, should be rolled regularly (3 months in summer, other seasons can be extended as appropriate). Rolling, will be stored down the side of the disk rolled over towards the top, so as to avoid the bottom side of the moisture decay. Storage should always pay attention to whether the cable head is intact. 6, cable storage period to the product factory period as a limit, generally should not exceed one and a half years, a long time not more than two years.
