The electric wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables), and branch cables. (Replaces some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment.
Wires and cables used in information transmission systems are mainly local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications or other composite cables.
Except for overhead bare wires, almost all other products are used in this part, but mainly power cables, electromagnetic wires, data cables, wire and cable manufacturers, instrumentation cables, etc.
The manufacture of wires and cables is completely different from the production method of most electromechanical products. Electromechanical products usually use other parts to be assembled into parts, and multiple parts are then assembled into a single product. The product is measured by the number of units or pieces. Wires and cables are based on length as a basic unit of measurement. All wires and cables start with conductor processing, and the insulation and shielding, cable formation, and sheathing are added to the outer layer of the conductor layer by layer to make wire and cable products. The more complex the product structure, the more layers there are.
I. The large-scale continuous superimposed combined production method has an overall and controlled impact on the production of wires and cables, which involves and affects:
(1) Production process and equipment layout
The various equipment in the production workshop must be reasonably discharged in accordance with the process required by the product, so that the semi-finished products at each stage are sequentially transferred. Equipment configuration must balance production capacity in consideration of different production efficiency. Some equipment may have to be equipped with two or more units in order to balance the production capacity of the production line. Therefore, the reasonable combination of equipment and the layout of the production site must be balanced and comprehensively considered according to the product and production volume.
(2) Production organization management
Production organization management must be scientific, reasonable, thorough, accurate, strict and meticulous. Operators must be meticulous in accordance with process requirements. Any problem in any link will affect the smooth flow of the process and affect the quality and delivery of products. Especially for multi-core cables, if a certain wire pair or basic unit is short in length, or there is a problem with quality, the entire cable will not be long enough, resulting in scrapping. Conversely, if a unit is too long, it must be sawed off to cause waste.
(3) Quality management
Large-length continuous stacking combined production mode makes any link in the production process instantaneous problems, which will affect the quality of the entire cable. The more the quality defect occurs in the inner layer and the termination of production is not found in time, the greater the loss caused. Because the production of wires and cables is different from assembled products, it can be disassembled and reassembled and replaced with other parts; the quality of any part of the wire or cable or the process is almost irreparable and irreparable for this cable. Afterwards, the treatment is very negative. It is either shortened or degraded, or the entire cable is scrapped. It cannot be disassembled and reassembled.
Wire and cable quality management must run through the entire production process. The quality management inspection department shall inspect the entire production process, perform self-inspection by operators, and perform mutual inspections of upper and lower processes. This is an important guarantee and means to ensure product quality and improve economic efficiency of enterprises.
