In terms of materials:
Conductors: The conductors of both cables are made of aluminum. Aluminum has the characteristic of being lightweight, which makes the cable more convenient during transportation, reducing transportation costs; during underground laying, it also reduces the handling burden of construction personnel and improves construction efficiency. Moreover, the cost of aluminum is relatively low, which can reduce the overall cost of the cable on the premise of ensuring that the conductivity meets the requirements, resulting in high cost performance.
Insulation Layer: Although the Insulation Material is not clearly specified, combined with the characteristics of high-voltage cables, it is usually equipped with a high-voltage resistant insulation layer such as cross-linked polyethylene (XLPE). The XLPE insulation layer has excellent high-voltage resistance, can withstand the electric field effect during high-voltage power transmission, and is not easy to be broken down. At the same time, it has good chemical corrosion resistance and aging resistance, and can maintain stable insulation performance for a long time in the underground humid environment with certain soil chemical substances, ensuring the safety of power transmission.
Sheath Layer: To adapt to the underground laying environment, the sheath layers of both cables usually use wear-resistant, corrosion-resistant, and moisture-proof materials. This kind of sheath layer can resist the pressure and friction of underground soil as well as the erosion of groundwater, protect the internal cores and insulation layers from damage, and extend the service life of the cable.
In terms of style:
95×4 3-Phase 4-Wire Underground Aluminum Cable: It adopts a 4-core cabling style, with 4 Cores combined in a certain stranding way and wrapped with a sheath layer on the outside. This style has a compact structure and strong integrity, which can reduce the occupied space during underground laying, and at the same time, can improve the mechanical strength of the cable to resist external impacts in the underground environment.
3×185 + 95mm High-Voltage Cable: 3 phase lines and 1 neutral line are stranded together to form an integral structure, with a sheath layer also wrapped on the outside. This style can ensure the stable relative position between phase lines and neutral lines, which is conducive to three-phase balance during power transmission, and at the same time, facilitates construction personnel to carry out laying and installation. Both cables have a relatively regular appearance and smooth surfaces, which are easy to pass through underground pipes.
Production Process of 95×4 3-Phase 4-Wire Underground Aluminum Cable:
Conductor Production: High-quality aluminum materials are selected, first smelted to remove impurities to improve the purity of aluminum, and then made into aluminum rods through rolling processes. Then, the aluminum rods are drawn into Aluminum Wires of the required diameter through wire drawing equipment, and then multiple Aluminum Wires are stranded together in a specified stranding way to form a conductor with a single-core cross-sectional area of 95mm². During the stranding process, the stranding pitch and tension are strictly controlled to ensure the roundness and conductivity of the conductor.
Insulation Layer Extrusion: Special extrusion equipment is used to heat and melt the insulation material, then uniformly extrude and wrap it around the conductor to form an insulation layer. During the extrusion process, parameters such as extrusion temperature and speed are accurately controlled to ensure that the insulation layer has uniform thickness, a smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities.
Cabling: 4 Cores wrapped with insulation layers are cabled in a certain stranding way. During the cabling process, appropriate filling materials are filled to make the cable structure round. Then, a layer of binding tape is wrapped around the outside to fix the position of the cores.
Sheath Extrusion: Wear-resistant, corrosion-resistant, and moisture-proof sheath materials are selected, extruded through an extruder, and wrapped around the cabled cable to form a sheath layer. After extrusion, the cable is cooled and solidified to make the sheath layer closely combine with the internal structure.
Inspection: The finished cable undergoes appearance inspection, size measurement, and electrical performance testing (such as insulation resistance testing and voltage withstand testing) to ensure that the cable quality meets the standards.
Production Process of 3×185 + 95mm High-Voltage Cable:
Conductor Production: Similar to the 95×4 cable, 3 phase line conductors with 185mm² and 1 neutral line conductor with 95mm² are produced respectively. During the production process, parameters of each link are strictly controlled to ensure the conductor quality.
Insulation Layer Extrusion: Due to being a high-voltage cable, the requirements for the insulation layer are higher. High-quality high-voltage resistant insulation materials are used. During the extrusion process, in addition to controlling conventional parameters, the thickness and uniformity of the insulation layer are more strictly controlled to ensure its high-voltage resistance. After extrusion, special treatments such as cross-linking may be required to further improve the performance of the insulation layer.
Cabling: 3 phase lines and 1 neutral line are cabled in a designed stranding way, and the positions of each core are reasonably arranged to ensure three-phase balance. Filling materials are filled and binding tapes are wrapped during the cabling process.
Sheath Extrusion: Sheath materials suitable for high-voltage cables and adaptable to the underground environment are selected, wrapped around the cabled cable through an extruder, and formed into a sheath layer after cooling and solidification.
Inspection: In addition to conventional inspection items, more stringent high-voltage withstand testing and partial discharge testing are required to ensure that the cable can operate safely and stably in a high-voltage environment.
Packaging Materials: Both cables are packaged with steel cable reels. Steel cable reels have the characteristics of high strength and high load-bearing capacity, which can bear the weight of the cable and external impacts during transportation and hoisting, and protect the cable from damage. At the same time, steel cable reels have good moisture-proof performance and can prevent the cable from getting damp to a certain extent.
Packaging Methods: The cable is neatly wound on the steel cable reel, and appropriate tension is maintained during the winding process to avoid the cable being loose or twisted. A layer of moisture-proof film is wrapped around the outer layer of the cable to further enhance the moisture-proof effect. On the side of the cable reel, information such as the model, specification, length, production date, and manufacturer of the cable is clearly marked for easy identification and traceability. To prevent the cable from slipping off the cable reel during transportation, special fixing devices are used to fix both ends of the cable.
Packaging Requirements: The packaging must be firm and reliable, and the size and strength of the cable reel must match the specification and length of the cable. The packaged cable must be able to adapt to various environments during transportation, such as vibration, bumps, and temperature changes, to ensure that the cable remains intact when it reaches the destination. At the same time, the packaging should be easy to hoist and transport, and special hoisting holes are set on the cable reel to facilitate loading and unloading with hoisting equipment.
Transportation Methods: According to the transportation distance and the number of cables, road transportation or railway transportation can be selected. For short-distance transportation, large trucks are used for transportation. The trucks are equipped with special fixing devices to fix the cable reels firmly to prevent movement during transportation. For long-distance transportation, railway transportation is chosen. Railway transportation has the characteristics of good stability and large transportation volume, which can reduce bumps and impacts on the cable during transportation.
Transportation Precautions: Before transportation, a comprehensive inspection of the cable reel is carried out to ensure that the cable is wound firmly and the fixing devices are reliable. During transportation, avoid severe collision and extrusion of the cable reel, and it is strictly forbidden to place the cable reel upside down or tilted. Obvious warning signs such as "Handle with Care" and "Do Not Invert" are set on the transport vehicle to remind transport personnel to pay attention. At the same time, avoid the cable being exposed to the sun, rain, and freezing during transportation. In severe weather conditions, the cable should be covered for protection. During transportation, drivers should drive steadily and avoid sudden braking and sharp turns to reduce the shaking of the cable reel.
Transportation Tracking: Arrange special personnel to track the transportation process and keep abreast of the transportation status of the cable.
