Wire and cable products to buy good will take into account the six factors
1 electrical properties
Refers to the high-frequency transmission characteristics Yanggu cable transmission characteristics, interference characteristics.
Electrical insulation properties --- insulation resistance, dielectric constant, dielectric loss resistance, electrical properties and so on.
Conductive properties --- most products require good electrical conductivity, specific resistance of the product requires a certain range.
2 other properties
Including some material properties (such as metal hardness, creep, polymer compatibility), and the use of some special product characteristics (such as the extension is not flammable, resistant to atomic radiation, anti-insect, transmission, and energy damping , etc.).
3 aging
Refers to the mechanical stress, electrical stress, thermal stress cable prices and various other under the action of external factors, or the role of external climatic conditions, the product and its constituent materials, the ability to maintain its original performance.
4 corrosion resistance and weather resistance
Refers to the resistance to electrochemical corrosion, erosion-resistant organisms and bacteria, resistance to chemicals (oil, acids, alkalis, solvents, etc.) erosion, salt spray, cable prices light, cold, mildew and moisture resistant and so on.
5 thermal performance
Refers to the product of the temperature level, the working temperature of power transmission wire and cable heating and cooling characteristics, carrying capacity, short circuit and overload, synthetic materials, the thermal deformation and thermal shock resistance, thermal expansion and material impregnated or coated drip properties.
6 mechanical properties
Refers to the tensile strength, elongation, bending, flexibility, softness Yanggu cable, shock-resistant nature of abrasion resistance and resistance to mechanical shock.
