Wire and cable companies believe that wire and cable need to be used in different situations, will come into contact with air, water, acid and alkali substances, etc. Sometimes even have to deal with a variety of harsh environment, so need to have different performance according to different requirements. The rated operating temperature of common wires and cables is generally 70 to 90. If it's a normal environment, you can do it. If you want to have higher temperature resistance rating, you need to use high temperature resistant materials to produce wire and cable, such as 105 and 125 new materials on the market.
Wire and cable companies believe that wire and cable anti-aging refers to the ability of wire and cable to maintain the original performance under the action of mechanical stress, electrical stress, thermal stress and other external factors, which can greatly delay aging and prolong the service life. Corrosion resistance of cable refers to electrochemical corrosion, biological corrosion, chemical (oil, acid, alkali, chemical solvent, etc.) corrosion resistance. Corrosion resistance, salt spray resistance, sun resistance, cold resistance, disease resistance, moisture resistance. Wires will inevitably come into contact with air, water, acid and other substances in the process of use. Its corrosion resistance can reduce the corrosion and weathering speed and degree of wires and cables in contact with these substances to a certain extent, while slowing down the aging speed and extending the service life.
Wire and cable companies argue that flame retardants have properties that prevent the spread of flames. This feature can make wire and cable in the event of an electrical fire is not easy to burn, greatly reducing the flame spread of wire and cable after burning. Fire-resistant wire and cable stress in the case of flame burning, can maintain safe operation in a certain time, to maintain the integrity of the line. It is used in high-rise buildings, subways, underground streets, large power stations, important industrial and mining enterprises and other places related to fire safety and fire rescue.
Wire and cable companies argue that wire and cable are manufactured in a completely different way from most electromechanical products. Mechanical and electrical products usually adopt the method of assembling another part into a part and assembling several parts into a product. Products are measured in units or pieces. The basic unit of measurement for wire is length. All wires and cables are made of conductors, insulation, shielding, cables, protective layers, etc. Add layer by layer to the periphery of the conductor. The more complex the product structure, the more layers there are.
The wire and cable company believes that all kinds of equipment in the production workshop should be arranged reasonably according to the process flow required by the product, so that the semi-finished products at each stage can be recycled in turn. Equipment allocation should consider differences in production efficiency and balance production capacity. Some equipment may need to be equipped with two or more units to balance the production capacity of the production line. Therefore, the reasonable selection and combination of equipment and the layout of the production site must be balanced and integrated according to the product and production capacity.
