In the main line of power system engineering, cable products used to transmit and distribute high-power electrical energy, including power cables of various voltage levels from 1 kV to 330 kV and above, and various insulation.
Communication cables and fiber optic cables
Wire and cable products for the transmission of audio and various telecommunication information above audio, including local telephone cables, long-distance symmetrical communication cables, coaxial communication cables, cables for telephone equipment and various communication lines. Optical fiber cable is a new high-tech product developed this year. It uses quartz and plastic as the base material to transmit information with light. It has the advantages of large capacity, small size and light weight. Since the 1990s, it has gradually replaced long-distance communication. coaxial cable.
Wire and cable properties - mechanical properties
Refers to tensile strength, elongation, bending, elasticity, flexibility, vibration resistance, abrasion resistance and mechanical impact resistance.
Wire and cable properties - thermal properties
Refers to the product's temperature resistance grade, working temperature, heating and heat dissipation characteristics of wires and cables for power transmission, current carrying capacity, short-circuit and overload capacity, thermal deformation and thermal shock capacity of synthetic materials, thermal expansion of materials, and impregnation or coating materials dripping performance, etc.
Wire and Cable Properties - Corrosion and Weather Resistance
Refers to galvanic corrosion resistance, biological and bacterial erosion resistance, chemical resistance (oil, acid, alkali, chemical solvent, etc.) erosion, salt spray resistance, light resistance, cold resistance, mildew resistance and moisture resistance.
