Introduction to raw material manufacturing of Cable Accessories in HYRS

In the power transmission and distribution system, cable accessories as an indispensable component, its performance and reliability for the whole power system is very important for the safe and stable operation.

First, the raw material composition of cable accessories

The raw material composition of cable accessories is rich and diverse, mainly covering plastic materials, metal materials, rubber materials and other aspects. The selection and application of these raw materials are not only related to the physical, electrical and chemical properties of cable accessories, but also directly affect their service life and safety.

1. Plastic materials

Plastic materials occupy an important position in cable accessories, of which PVC(polyvinyl chloride) is widely used in the production of low-voltage cables because of its good heat resistance, electrical insulation and corrosion resistance. Nylon, as a high-strength plastic material, is suitable for the manufacture of high-voltage cable accessories, such as support rings and brackets, because of its excellent compressive and tensile strength.

2. Metal materials

Metal materials are also indispensable in the manufacture of cable accessories. Because of its light weight and high strength characteristics, aluminum alloy is often used in the production of cable heads and joints, and has good electrical conductivity and corrosion resistance. Stainless steel, as a metal material with good corrosion resistance, is widely used in the manufacture of high voltage cable accessories, such as support parts, clamping rings, etc.

3. Rubber material

Rubber materials are mainly used in cable accessories to make seals, jackets and other components. Silicone rubber is preferred for its high temperature resistance, aging resistance and air tightness, and is suitable for the manufacture of cable heads and connectors in high temperature environments. Neoprene rubber occupies a place in the manufacture of cable accessories in industrial environments because of its good oil resistance and wear resistance.

Second, Manufacturing process of raw materials for cable accessories

The raw material manufacturing of cable accessories involves a number of process links, among which injection molding, cold extrusion, drawing, forging, machining and other processes are common manufacturing means. The selection and application of these processes need to be reasonably matched according to the specific type of cable accessories, performance requirements and cost budgets.

Taking injection molding as an example, the process uses an injection molding machine to inject a heat-melted plastic material into a mold, which is cooled and solidified to obtain the desired shape. Injection molding has the advantages of high production efficiency and high product accuracy, and occupies an important position in the manufacture of cable accessories.

Third, the quality control of cable accessories raw materials

The quality control of cable accessories is the key to ensure the stability and reliability of cable accessories. In all aspects of raw material procurement, manufacturing, quality testing and so on, it is necessary to operate in strict accordance with relevant standards and norms to ensure the quality of raw materials is reliable and stable.

At the same time, the quality inspection of cable accessories can not be ignored. Through raw material testing, product testing, finished product testing and other links of cable accessories, to ensure that the performance and quality of cable accessories can meet customer needs, reduce the defect rate and defective rate of products.

The raw material manufacturing of cable accessories is a complex and delicate process, involving many aspects of raw material selection and process application. Through in-depth understanding of the raw material composition, manufacturing process and quality control of cable accessories, we can better understand the performance and quality of cable accessories, and provide a strong guarantee for the safe and stable operation of the power system.
