Electrical properties of power cables
Electric conductivity — Most products require good electrical conductivity, and individual products require a certain range of resistance..
Performance Electrical isolation — insulation resistance, dielectric coefficient, dielectric loss, electrical resistance characteristics, etc.
transmission characteristics — refers to high frequency transmission characteristics, anti-interference characteristics, etc.
Mechanical properties of power cables
Refers to tensile strength, elongation, bending capacity, elasticity, flexibility, vibration resistance, wear resistance and resistance to mechanical force impact, etc.
Thermal properties of power cables
Refers to the level of temperature resistance of the product.
Operating temperature of wire and cable for power transmission, heat and heat dissipation characteristics, Loading capacity, short circuit and overload capacity.
Thermal deformability and thermal shock resistance of synthetic materials.
The thermal expansion of the material and the dripping performance of the impregnated or coated material, etc.
Corrosion and weather resistance of power cables
Refers to resistance to electrochemical corrosion, resistance to biological and bacterial erosion, chemical resistance (oil, acid, alkali, chemical solvents, etc.) to erosion, salt spray resistance, light resistance, cold resistance, mold resistance and moisture resistance.
Aging performance of power cord
Refers to mechanical stress, electric tension, thermal stress and various other external factors.
Or the role of external climatic conditions, the product and the materials that compose it to maintain its original performance.
Other properties of power cables
Including the characteristics of some materials (as hardness of metallic materials, creep, compatibility of polymer materials).
As well as certain special features of the use of the product (as non-flammability, resistance to atomic radiation, insect bites, transmission delay, energy damping, etc.).
Product performance requirements, mainly from the use of each specific product, the conditions of use, as well as the support team and other aspects of the relationship.
In a product of various performance requirements, there are likely to be some of the main and decisive , must be strictly required. Some of them are gender.
Sometimes certain factors are constrained by each other. Therefore, it is necessary to study and analyze the comprehensive consideration.
