Rubber sheathed cable YCW3 * 25 heavy-duty rubber sheathed flexible cable YCW3 * 35

General rubber sheathed flexible cables, abbreviated as rubber sheathed cables, are divided into high-voltage rubber sheathed flexible cables and 750V general rubber sheathed flexible cables. Application of high-voltage rubber sheathed flexible cable: Mobile power distribution equipment and mining machinery with AC rated voltage of 6kV and below; Lifting and transportation machinery, etc. Low voltage rubber sheathed flexible cables are suitable for household appliances, power tools, and various mobile electrical equipment with an AC rated voltage of 750V and below. There are three types of cables: light, medium, and heavy.

The quality management of wires and cables must be integrated throughout the entire production process. The quality management inspection department should conduct patrol inspections, self inspections by operators, and mutual inspections between upper and lower processes throughout the entire production process. This is an important guarantee and means to ensure product quality and improve the economic efficiency of the enterprise.
1. There are multiple types of production processes and large material flow rates
The manufacturing of wires and cables involves a wide range of processes, from the melting and pressure processing of non-ferrous metals to chemical technologies such as plastics, rubber, and paint; The textile technology of wrapping and weaving fiber materials, to the wrapping of metal materials and the longitudinal wrapping and welding of metal strips, and so on.
The various materials used in the manufacturing of wires and cables are not only diverse in categories, varieties, and specifications, but also in large quantities. Therefore, the dosage, reserve quantity, batch cycle, and batch size of various materials must be determined. At the same time, the decomposition, recycling, reuse, and disposal of waste materials are important aspects of management, and material quota management and conservation work should be emphasized.
In the production of wires and cables, from the entry and storage of raw materials and various auxiliary materials, the flow of semi-finished products in each process to the storage and delivery of products, the material flow is large, and it must be reasonably laid out and dynamically managed.
2. Multiple devices
The manufacturing of wires and cables uses production equipment with the characteristics of the industry's technology to adapt to the structural and performance requirements of cable products, meet the requirements of long continuous and high-speed production, and thus form a series of equipment for cable manufacturing. Such as extruder series, wire drawing machine series, wire twisting machine series, winding machine series, etc.
The manufacturing process and equipment development of wires and cables are closely related and mutually promote each other. New process requirements promote the emergence and development of new equipment; On the other hand, the development of new equipment has also promoted the promotion and application of new processes. Such as wire drawing, annealing, extrusion series line; Equipment such as physical foaming production lines have promoted the development and improvement of wire and cable manufacturing processes, enhancing the product quality and production efficiency of cables.

Basic process flow of cable manufacturing
1. Copper and aluminum monofilament drawing
Copper and aluminum rods commonly used in wires and cables are drawn through one or several stretching molds using a drawing machine at room temperature to reduce their cross-section, increase their length, and improve their strength. Drawing is the first process of various wire and cable companies, and the main process parameter of drawing is mold matching technology.
2. Single wire annealing
Copper and aluminum monofilaments are heated to a certain temperature to improve their toughness and reduce their strength through recrystallization, in order to meet the requirements of wire and cable for conductive cores. The key to annealing process is to prevent oxidation of copper wire
3. Twisting of conductors
In order to improve the flexibility of wires and cables for easy installation, the conductive core is made up of multiple single wires twisted together. From the twisting form of the conductive wire core, it can be divided into regular twisting and irregular twisting. Irregular twisting can be divided into bundle twisting, concentric compound twisting, special twisting, etc.
In order to reduce the occupied area of wires and shrink the geometric dimensions of cables, a compression form is adopted while twisting conductors, transforming ordinary circles into semicircles, sectors, tile shapes, and compressed circles. This type of conductor is mainly used in power cables.
4. Insulation extrusion
Plastic wires and cables mainly use extruded solid insulation layer. The main technical requirements for plastic insulation extrusion are:
4.1. Eccentricity: The deviation value of the extruded insulation thickness is an important indicator of the extrusion process level, and most product structural dimensions and their deviation values are clearly specified in the standard.
