Wire and cable products are used in different occasions, and the performance requirements are various and extensive. The main performance can be integrated into the following items:
- Electrical properties: including electrical conductivity, electrical insulation properties and transmission properties. Conductivity – Most products require good conductivity, and some products require a certain resistance range.
- Mechanical properties: refer to tensile strength, elongation, flexibility, elasticity, flexibility, fatigue resistance, wear resistance and impact resistance.
- Thermal performance: refers to the product’s heat resistance grade, working temperature, heating and heat dissipation characteristics of power cables, current carrying capacity, short-circuit and overload capacity, thermal deformation and thermal shock capacity of synthetic materials, thermal expansion of materials and impregnation or drawing. The dripping properties of the layer material, etc.
- Corrosion resistance and weather resistance: It refers to galvanic corrosion resistance, biological and erosion resistance, chemical resistance (oil, acid, alkali, chemical solvent, etc.) erosion, salt spray resistance, sunlight resistance, cold resistance, anti-virus and moisture resistance.
- Aging resistance: refers to the ability of the product and its constituent materials to maintain their original performance under the action of mechanical stress, electrical stress, thermal stress and various other external factors, or under external climatic conditions.
- Other properties: including the properties of some materials (such as hardness, creep of metal materials, compatibility of polymer materials, etc.) and some special characteristics of products (such as flame retardant, fire resistance, waterproof, insect bite, anti rat ants, etc.).
