What is the knowledge of wire and cable performance?

Jul 02,2018

Wire and cable products are used on different occasions, so the functional requirements are many and very extensive. Looking at the whole, its primary function is summarized as:

1. Electrical function

Conductive Functions - Most products require outstanding electrical conductivity, and individual commodity requirements have a certain resistance scale.

Electrical insulation function - insulation resistance, dielectric coefficient, dielectric loss, electrical resistance and so on.

Transmission characteristics - refers to high-frequency transmission characteristics, anti-jamming characteristics.

Wire and Cable

2. Mechanical function

Refers to tensile strength, elongation, flexibility, elasticity, softness, sensation resistance, wear resistance and mechanical impact resistance.

3. Thermal function

Refers to the temperature resistance grade of the product, the heating and heat dissipation characteristics of the wire and cable for the power transmission, the current carrying capacity, the short-circuit and overload capability, the thermal deformability and thermal shock resistance of the constituent materials, the thermal expansion of the data, and the data of the impregnation or coating. Drop function, etc.

4. Corrosion and weather resistance

Refers to resistance to electro-chemical corrosion, bio- and bacterial corrosion, chemical resistance (oil, acid, alkali, chemical solvents, etc.) corrosion, salt spray resistance, light resistance, cold resistance, mildew resistance and moisture resistance.

5. Aging function

Refers to the ability of commodities and their constituent materials to adhere to their original functions under the effects of mechanical stress, electrical stress, thermal stress and other various external factors, or under the influence of external climatic conditions.

6. Other functions

Including the characteristics of some data (such as hardness, creep of metal data, compatibility of polymer data), and some special features of the product (such as non-flammability, atomic radiation resistance, insect resistance, delayed transmission, and Energy damping, etc.).

Wire and Cable

The functional requirements of goods are firstly proposed from the aspects of the use of each detailed product, the conditions of use, and the matching of supporting equipment. In the functional requirements of a commodity, there must be some of the most important ones. It has a decisive effect and should be strictly required. Some are affiliated. Sometimes certain elements are mutually restrictive. Therefore, it is necessary to conduct a comprehensive study and analysis of inductive thinking.

Henan Sanheng Cable Co., Ltd , founded in 2000, It is one of the top wire and cable manufacturers in China's wire and cable industry for nearly 20 years. the company has more than 5 production lines.

The production cable can be divided into more than 50 varieties and subdivided into 1000 specifications.All products have passed national certification, such as China compulsory certification, bv certification, Nigerian SONCAP certificate, China national industrial certification, etc. China national industrial production license, etc.It also has the ability to produce products that meet international standards, such as iec, ce, rohs, etc.
If you want to buy wires and cables, you can ask the customer service staff and we will get back to you as soon as possible.
