The basic characteristics of wire and cable
1, Electrical properties
Conductive performance: Conductive core resistance (DC resistance wire), carrying capacity.
Electrical insulation properties: insulation resistance, withstand voltage characteristics.
2, Mechanical properties
Refers to the tensile strength, elongation, flexibility, flexibility, resistance to vibration, abrasion resistance and impact resistance.
3, Thermal performance
Refers to the product's thermal rating, operating temperature, cable heating and cooling characteristics, current carrying and overload capacity, thermal deformation and thermal shock resistance of composite materials, thermal expansion properties of materials and dripping properties of impregnated or coated materials, etc. .
4, Corrosion and weather resistance
Refers to the resistance to electrochemical corrosion, resistance to biological and bacterial erosion, chemical resistance (oil, acid, alkali, chemical solvents, etc.) erosion, salt spray resistance, sunlight, cold, mold and moisture resistance.
5, Aging performance
Refers to the mechanical (force) stress, electrical stress, thermal stress and other various external factors, or under external climatic conditions, the product and its constituent materials to maintain its original ability.
6, Other performance
Including the characteristics of materials (such as the hardness of metal materials, creep, compatibility of polymer materials) and some special characteristics of the product (such as flame retardant, etc.).
