National standard cable products are used in different places, so the role requirements are all aspects, very common. From the perspective of all personnel, its main role is sorted out as follows:

1. Electrical action

Electrical conductivity - most products require good electrical conductivity, and individual products require a certain scale of operation of resistors.

Insulation function - ground resistance, electric polarization index, dielectric loss, electric resistance, etc.

Transmission characteristics - refers to the characteristics of high frequency transmission, anti-interference characteristics, etc.

2. Role of mechanical equipment

Refers to compressive strength, elongation, bending, ductility, flexibility, resistance to bombardment, wear loss and resistance to the impact of mechanical equipment. Cable line

3. Heat action

Refers to the high temperature level of the product, the operating temperature of the national standard cable for electric power engineering transmission, the scorching and heat removal characteristics, the cable carrying capacity, short circuit fault and load can be allowed, the thermal deformation of the component material and the high temperature impact resistance can be allowed, the thermal deformation of the material and the drip effect of the prepreg or coating material.

4. Corrosion resistance and weather resistance

Refers to heat resistance, microbial and bacterial corrosion resistance, chemical (oil, acid, alkali, organic chemical organic solvent, etc.) corrosion resistance, corrosion resistance, light resistance, low temperature resistance, mildew removal and waterproof effect.

5. Embrittlement

Refers to the actual effect of mechanical equipment ground stress, electrical ground stress, internal stress and a variety of other additional factors, or the actual effect of external climate conditions, the product and the composition of the material can persist in its original role.

6. National standard cable other functions

Contains the characteristics of some materials (such as the strength of metal materials, stress relaxation, the compatibility of polymer materials) and some of the special application characteristics of its products (such as non-delayed combustion, resistance to molecular radiation sources, anti-bite, delayed transmission, and its kinetic energy vibration reduction, etc.).

The role of the product requirements, mainly based on the use of each detailed product, application standards, and the mutual coordination and liaison of its supporting facilities are clearly proposed. In the various role requirements of a product, there are inevitably some are the main, the actual effect of decision-making, should be strict requirements. Some of them belong to. Sometimes factors are interdependent. Therefore, it is necessary to discuss and analyze in various aspects.
