It supports a variety of laying methods, including direct burial laying, pipe laying and bridge laying. It can be flexibly selected according to the structure of different buildings and construction requirements, which greatly improves the convenience of construction.
(III) Material and Style
The conductor of TTU cable is made of high-purity electrolytic copper, with a purity of more than 99.95%. This high-purity Copper Conductor has excellent electrical conductivity, which can effectively reduce energy loss during power transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and Flexibility, which makes the cable easier to operate during laying and installation, and reduces damage to the conductor caused by bending and stretching. The insulation layer is made of cross-linked polyethylene (XLPE). XLPE has excellent insulation performance, which can withstand higher voltage, effectively prevent current leakage and ensure electrical safety. It also has good heat resistance. It can maintain stable insulation performance at a long-term working temperature of 90℃, and will not have problems such as insulation aging and performance decline due to temperature rise. In addition, XLPE has good chemical stability and is not easy to be corroded by external chemical substances, which helps to extend the service life of the cable.
The cable is of a single-core circular style, with a black appearance and a smooth surface. The black color not only looks neat but also has certain light resistance, which can reduce the damage to the cable surface caused by direct sunlight. The circular structure makes the cable bear force evenly during laying, which is convenient for threading and wiring. At the same time, it can also reduce the damage caused by external collision during use. The smooth surface reduces the friction during laying, facilitates construction, and reduces the adhesion of dust and impurities, making daily maintenance and cleaning easier.
(IV) Production Process
The production of TTU cable goes through a series of strict and standardized processes. First of all, high-purity electrolytic copper rods are drawn into Copper Wires of the required diameter through multiple wire drawing processes. In the wire drawing process, the drawing speed and the precision of the mold are strictly controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth without defects. Then, the copper wire is annealed. Through controlling the temperature and time of annealing, the mechanical properties of the copper wire are improved, and its flexibility and ductility are enhanced, laying a good foundation for subsequent processing. Next is the extrusion of the insulation layer. Special extrusion equipment is used to heat and melt the XLPE material, and then evenly coat it on the surface of the conductor to form the insulation layer. During the extrusion process, parameters such as extrusion temperature, pressure and speed are accurately controlled to ensure that the insulation layer has a uniform thickness, is closely combined with the conductor, and has no defects such as bubbles, depressions and protrusions. After extrusion, the cable is cross-linked. In a high-temperature and high-pressure environment, the XLPE molecules form a three-dimensional network structure, which significantly improves its insulation performance, heat resistance and mechanical strength.
After cross-linking, the cable needs to be cooled and shaped to maintain a stable structure and size. During the cooling process, the cooling speed is controlled to avoid cracks on the cable surface due to too fast cooling. Then, the cable undergoes a series of performance tests, including insulation resistance test, voltage withstand test and mechanical performance test, to ensure that each section of the cable meets the relevant quality standards. Finally, the qualified cables are cut and coiled to complete the entire production process.
II. General Product Information
(I) Packaging
TTU cables are packaged with wooden reels. The wooden reels are made of high-quality pine, which has sufficient strength and stability to bear the weight of the cables and resist external impacts during transportation. The diameter of the wooden reel is determined according to the specification and length of the cable. Generally, the diameter of the wooden reel for small-size cables is relatively small, and that for large-size cables is relatively large. This is to ensure that the cable is evenly stressed during winding and avoid loosening or deformation.
The cables are neatly wound on the wooden reels. Isolation paper is placed between each layer of cables to prevent surface damage caused by friction between cables. During the winding process, the winding tension is properly controlled to make the cables arranged closely, reducing the shaking of the cables during transportation. Both sides of the wooden reel are equipped with firm baffles. The baffles are marked with cable specifications, length, model, production date and other information, which is convenient for identification and traceability. At the same time, a moisture-proof film is covered on the outside of the wooden reel, which can effectively prevent the cable from getting damp during storage and transportation and protect the performance of the cable.
For small batches of cables, carton packaging can also be used. The cartons are made of high-strength corrugated paper. Buffer materials such as foam boards and bubble films are placed inside the cartons to fix the cables in the cartons and avoid collision and friction during transportation. The surface of the carton is also marked with relevant product information, which is convenient for handling and management.
(II) Transportation
When transporting TTU cables, appropriate transportation methods should be selected according to the transportation distance and the quantity of cables. For short-distance transportation with a small number of cables, small trucks can be used. During transportation, the wooden reels or cartons of the cables must be fixed firmly to prevent sliding and tipping during the driving of the vehicle. The driver should drive steadily, avoiding sudden braking and sharp turns to reduce the impact on the cables.
For long-distance transportation, large freight trucks or container transportation are usually used. When using large freight trucks for transportation, anti-skid pads should be laid in the carriage. The wooden reels of the cables should be arranged in order and fixed with steel wire ropes or fastening belts. Container transportation can provide better protection for cables, avoiding the impact of external weather, dust and other factors. When loading, care should be taken to prevent the cables from being squeezed and collided. It is strictly forbidden to stack heavy objects on the cables.
During transportation, moisture-proof, sun-proof and high-temperature prevention measures should be taken. In rainy or humid weather, the cables should be covered to prevent them from getting damp. In high-temperature weather, the cables should be avoided from being exposed to the sun for a long time. They can be parked in a cool place or shaded. The transport personnel should regularly check the packaging of the cables. If problems such as packaging damage and cable exposure are found, remedial measures should be taken in time to ensure the safety of the cables during transportation.
