Test Standards for Types of Electrical Wires and Cables

In the International Standard Classification, Wire and cable testing involves insulation materials, fire protection, components and accessories for telecommunication equipment, wires and cables, and optical fiber communications. In the Chinese standard classification, wire and cable testing involves electrical insulating materials and their products, cables and their accessories, fire protection, electrical materials and general parts.Wire and cable are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion.

The generalized wire and cable is also referred to as the cable, and the narrowly defined cable refers to the insulated cable. With the development of the power industry in Southeast Asia, the requirements for supporting industries are getting higher and higher. As an important part of the power supporting industry, wires and cables are no exception. They are facing the need for upgrading to meet the needs of the overall power development.

Future wire and cable enterprises should work hard on improving technology, saving raw materials, and developing new environmentally friendly materials. The development of the wire and cable industry has promoted the development of power transmission and distribution, power transmission and other industries. With the development of power, data communication, urban rail transit and other industries in the Asia-Pacific region, the demand for wire and cable products has increased, which has promoted the scale of the industry improvement.

The development of carbon fiber is getting faster and faster in recent years. One possibility is that carbon fiber cable may replace the traditional steel core aluminum stranded wire in the future. Carbon fiber cable is an alternative to traditional steel core aluminum stranded wire (bare wire), mainly used in 110kV ~ 220kV lines. Compared with the conventional steel core aluminum conductor (ACSR), the aluminum cross-sectional area of ​​the ACCC is increased by 29%, and the weight per unit length is 20% lighter. loss.

Cable companies can realize power grid expansion without adding new lines by replacing a large number of ordinary conductors with ACCC conductors, greatly saving land, towers, and engineering costs, and in line with the policy direction of energy conservation and efficiency enhancement. Wewon Environmental Chambers Co., Ltd. as a professional manufacturer of wire and cable testing laboratory equipment favored by Chinese foreign trade enterprises. With perfect qualifications, profound technical capabilities, high-quality service guarantees, authoritative credibility and convenient national service network, we provide one-stop overall technical solutions for wire and cable testing equipment for various industries around the world.

High temperature superconducting technology will be greatly developed in the future. Due to the advantages of relatively low price, large capacity, low loss, and no electromagnetic pollution, high-temperature superconducting cables are highly valued internationally, and many countries have raised the development of superconducting industry to a strategic level. China has made major breakthroughs in high-temperature superconducting technology. Therefore, the research and development and application of high-temperature superconducting technology will be an important technology for the wire and cable industry in the future.

With the emergence of environmental pollution such as smog, today’s people pay more and more attention to environmental protection, and the wire and cable industry is no exception, and will inevitably face environmental protection requirements. The environmental protection of the wire and cable industry mainly refers to the environmental protection of materials.At present, a large number of polymer chemical materials such as rubber, polyvinyl chloride and polyethylene are used in the production of wire and cable. A large amount of toxic and harmful gases are produced in the production process.

Therefore, It is necessary to actively develop environmentally friendly materials and produce environmentally friendly wires and cables. From the perspective of wire and cable installation, it is also facing a new development trend, that is, the sheath is thin and the cross-section is miniaturized. In view of the convenience of installation, use and transportation, and at the same time reducing the cost of raw materials as much as possible, wire and cable products have an increasing tendency to develop, that is, cables develop into thinner sheaths and smaller cross-sections, while ensuring the current carrying capacity.

Insulation resistance reflects an important indicator of the insulation properties of wire and cable products, which is closely related to the electrical strength of the product, dielectric loss, and the gradual deterioration of insulating materials under working conditions.	Insulation Resistance Test
Determination of insulation resistance can find defects in the process: such as insulation dry and impervious or sheath damaged and damp; insulation is polluted and mixed with conductive impurities; insulation layer cracking caused by various reasons, etc.
For communication cables, if the insulation resistance between wires is too low, it will also increase loop attenuation, crosstalk between loops, and long-distance power supply leakage on the conductive core. Therefore, the insulation resistance is required to be higher than the specified value.
When the AC voltage is applied to the cable, a current flows. When the amplitude and frequency of the voltage are constant, the magnitude of the capacitor current is proportional to the capacitance (Cx) of the cable.	Measurement of Capacitance and Dissipation Factor
For ultra-high voltage cables, the current of this capacitor may reach a value comparable to the rated current, which becomes an important factor limiting the cable capacity and transmission distance. Therefore, the capacitance of the cable is also one of the main electrical performance parameters of the cable.
In the AC electric field, the insulator in the cable will form dielectric loss due to leakage current and various polarizations, which is expressed by the dielectric loss factor or loss tangent (TANδ), which not only wastes electric energy, but also makes the dielectric (insulator) loss. ) generates heat and accelerates insulation aging, so TANδ is also one of the main parameters of the cable.

The insulation strength of a wire and cable refers to the ability of the insulating structure and insulating material to withstand the action of an electric field without breakdown damage. In order to check the quality of wire and cable products and ensure the safe operation of the product, all insulation types of wires and cables are generally subject to insulation strength tests. Dielectric strength test can be divided into withstand voltage test and breakdown test.	Dielectric Strength Test
The withstand voltage test is to apply a certain voltage to the test product under certain conditions, and after a certain period of time, whether the breakdown occurs is used as the criterion for judging whether the test product is qualified. The time voltage is generally higher than the rated working voltage of the test product, and the specific voltage value and withstand voltage time are specified in the product standard.
The breakdown test is to measure the breakdown field strength or breakdown voltage under certain test conditions, increase the voltage until the breakdown of the sample occurs. Through the breakdown test, the safety margin between the ability of the cable to withstand the voltage and the working voltage can be assessed. One of the important parameters in cable design at breakdown field strength.
The aging test is a stability test that can maintain stable performance under the action of stress (mechanical, electrical, thermal). The simple thermal aging test is to test the aging characteristics of the sample under the action of heat: put the sample in an environment with a temperature higher than the rated working temperature, and after a specified time, measure some sensitive properties before and after aging. change to assess aging characteristics.	Aging and Stability Test
It is also possible to accelerate the aging of the test sample by increasing the temperature, and add thermal, mechanical, and electrical stresses such as moisture, vibration, and electric fields to form an aging cycle. After each aging cycle, certain selected sensitive performance parameters are determined.
