Industrial Equipment Power Distribution: In industrial production, various equipment have different power requirements. The 1/0AWG specification cable can be used for power distribution of small grinders, small pumps and other equipment, and its current-carrying capacity can stably meet the power demand of these equipment. The 2/0AWG and 3/0AWG specifications are suitable for medium-power industrial equipment, such as CNC machine tools and medium-sized compressors, and can provide continuous and stable power support for these equipment. The 4/0AWG, 500mcm, and 600mcm specifications can be used for large industrial equipment, such as large injection molding machines and heavy machine tools, to ensure the normal operation of these high-power equipment. There may be certain mechanical vibrations and oil stains in the industrial environment. The PVC Sheath of Ttu cable has good mechanical protection and oil resistance, and can adapt to such an environment.

Building Internal Wiring: In construction projects, Ttu cables can be used for internal wiring. For small commercial buildings, such as convenience stores and small offices, 1/0AWG and 2/0AWG specifications can be used as wiring cables for lighting, air conditioners and other equipment. For medium-sized buildings, such as multi-storey office buildings and shopping malls, 3/0AWG and 4/0AWG specifications can meet the power distribution needs of larger areas and are used to connect floor distribution boxes and electrical equipment in various areas. Some main wiring of large buildings can choose 500mcm and 600mcm specifications to ensure efficient transmission of electricity from the main distribution room to each partition distribution system. The internal wiring environment of the building is complex, and the cable needs to have certain moisture resistance and extrusion resistance. The XLPE insulation layer and PVC sheath of this cable can well meet these requirements.

Low-Voltage Power Transmission Lines: In some low-voltage power transmission scenarios, such as power transmission inside the factory area and power distribution trunk lines in residential areas, Ttu cables are ideal choices. For lines with short transmission distance and small power demand, 1/0AWG to 3/0AWG specifications can be selected; for lines with longer transmission distance and larger power demand, 4/0AWG and above specifications are more appropriate. Its Copper Conductor has excellent conductivity, which can reduce loss during power transmission and ensure efficient transmission of electricity to the destination. At the same time, the quality in line with IEC 60502 standard also ensures the safe and stable operation of the line.

Materials

Style

Conductor Production: High-purity copper materials are selected, and impurities are removed through smelting to improve the purity of copper. Then, the copper material is processed into copper rods, and then the copper rods are drawn into Copper Wires of different diameters through wire drawing equipment. The diameter of the copper wire is determined according to the specification of the cable. For conductors that need multi-strand stranding, multiple copper wires are stranded according to a specific stranding process to form conductors of the required specifications. During the stranding process, the stranding pitch and tension are strictly controlled to ensure the roundness of the conductor and uniform conductivity.

Insulation Layer Extrusion: Special extrusion equipment is used to heat the XLPE material to a molten state, and uniformly extrude and coat it on the surface of the conductor through an extrusion die to form an insulation layer. During the extrusion process, the extrusion temperature, speed and pressure are accurately controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, is closely combined with the conductor, and has no defects such as bubbles and impurities. After extrusion, the insulation layer is cross-linked, and the XLPE molecules form a network structure by heating to enhance the temperature resistance and mechanical strength of the insulation layer.

Sheath Extrusion: The conductor treated with the insulation layer is sent to the sheath extrusion equipment. The PVC material is heated and melted, and then uniformly extruded and coated on the outside of the insulation layer to form a sheath layer. The extrusion parameters are controlled to ensure that the sheath layer has a uniform thickness, is closely attached to the insulation layer, and has a flat surface. The extruded cable is cooled to make the sheath layer solidify and form quickly.

Finished Product Inspection: The finished cables are fully inspected. In terms of appearance inspection, check whether the cable surface is smooth, whether there is damage, and whether the marks are clear. Dimensional inspection includes conductor diameter, insulation layer thickness, sheath thickness, cable outer diameter, etc., to ensure they meet the specification requirements. Electrical performance tests include insulation resistance test and voltage withstand test to verify the insulation performance and voltage withstand capacity of the cable. Only cables that pass all inspection items can leave the factory.

Packaging Materials: Ttu cables use different packaging materials according to their specifications and quantities. For small-specification and short-length cables, plastic reels can be used for packaging. Plastic reels are light in weight and low in cost, and are convenient for carrying and storage. Large-specification and long-length cables are packaged with wooden cable reels or steel cable reels. Wooden cable reels have certain buffering performance, and steel cable reels have high strength and strong bearing capacity, which can better protect the cables from damage during transportation and storage.

Packaging Methods: The cable is neatly wound on the reel or cable reel, and appropriate tension is maintained during winding to avoid the cable being loose or twisted. A layer of moisture-proof film is wrapped around the outer layer of the cable to prevent the cable from getting damp. For wooden and steel cable reels, the specifications, models, lengths, manufacturers, production dates, IEC 60502 standard marks and other information of the cables are marked on the side. To prevent the cable from being damaged by collision during transportation, protective baffles are installed on the edge of the cable reel.

Packaging Requirements: The packaging must be firm and reliable, able to withstand external forces during transportation and handling, and prevent the cable from moving and wearing in the packaging. The packaging should have good moisture-proof and dust-proof performance to prevent the cable from being polluted and eroded by the external environment. At the same time, the packaging should be easy to load, unload and transport. Lifting holes are set on the cable reel to facilitate the use of lifting equipment.

Transportation Methods: Short-distance transportation can use truck transportation. The truck is equipped with fixing devices to fix the cable reels or cable drums firmly to prevent shaking during transportation. For long-distance transportation, railway transportation or long-distance road transportation can be chosen. Railway transportation has good stability and large transportation capacity, which is suitable for large quantities of cable transportation; long-distance road transportation has high Flexibility and can reach the destination directly. For export products, sea transportation can also be used.

Transportation Precautions: Before transportation, check whether the packaging of the cable is intact and whether the fixing is firm. During transportation, avoid the cable from being severely collided, squeezed, exposed to the sun and rain. It is strictly forbidden to invert the cable reel or cable drum to prevent the cable from falling and being damaged. Warning signs such as "Handle with Care" and "Moisture-proof" are set on the transport vehicle to remind transport personnel to pay attention. When transporting in low or high temperature environments, take corresponding protective measures to avoid the impact of extreme temperatures on cable performance.

Transportation Tracking: Arrange special personnel to be responsible for transportation tracking. Keep in touch with the transport driver or logistics company to keep abreast of the transportation progress and location of the cable. Master the weather, road and other conditions during transportation. If abnormal conditions are encountered, take timely countermeasures to ensure that the cable arrives at the destination on time and safely.

Delivery Process: After the customer places an order, the sales staff will transmit the order information to the warehouse. The warehouse staff check the specifications, models, quantities, etc. of the cables according to the order to ensure they are consistent with the order. Conduct a pre-shipment inspection of the cable to confirm that the packaging is intact and the marks are clear. Then arrange transport vehicles and go through the delivery procedures. After loading and fixing the cable on the transport vehicle, inform the customer of the transport information, such as the license plate number, driver's contact information, and estimated arrival time.

Delivery Time: When there is sufficient inventory, delivery is generally completed within 1-3 working days. If it is a customized specification or there is insufficient inventory, the delivery time is determined according to the production cycle, and the customer is promptly communicated with to inform them of the production progress and estimated delivery time, allowing the customer to arrange reasonably.

Delivery Notification: After the cable is shipped, notify the customer via SMS, phone call or email, inform the customer that the goods have been shipped, and provide information such as the logistics order number to facilitate the customer to track the goods.
