Product Description

Product Description

Low voltage aluminum core cable Low voltage aluminum core cable refers to a power cable with a rated voltage of 1kV (1000 volts) and below, using aluminum material as the conductor. It is the fundamental component used for transmitting and distributing electrical energy in the power system, widely applied in various links from substations to user terminals. Low voltage aluminum core cable is an economical and efficient power transmission solution, especially suitable for fixed installation, long-distance, and large cross-section application scenarios. The key to its successful application lies in the correct selection and extremely reliable connection process. With the advancement of connection technology and material processes, its original shortcomings are constantly being overcome, playing an indispensable role in modern power systems.Basic structure:Common models and meanings:Conductor: Made of high-purity electrical aluminum (usually rare earth aluminum), mostly in the form of multiple stranded strands to improve the flexibility and bending performance of the cable.
Insulation layer: wrapped around the conductor to provide insulation. Common materials include:
Polyvinyl chloride (PVC): code V, low cost, corrosion-resistant, but with a lower temperature resistance level (70 ℃).
Cross linked polyethylene (XLPE): code YJ, with better mechanical properties and heat resistance (long-term allowable working temperature of 90 ℃), higher current carrying capacity, is currently the mainstream choice.
Filler layer: In multi-core cables, it is used to fill the gaps between conductors, keeping the cable round and structurally stable.
Inner sheath/armor layer (optional):
Armor: such as steel tape armor (code 22), used to enhance the compressive and impact resistance of cables, suitable for direct burial or situations prone to external damage.
Outer sheath: The outermost protective layer, usually made of polyvinyl chloride (PVC) or polyethylene (PE), which serves to protect the internal structure of the cable from mechanical damage, chemical corrosion, and environmental influences.Chinese cable models usually use pinyin letters to represent materials and structures.
VLV: Aluminum core PVC insulated PVC sheathed power cable.
YJLV: Aluminum core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable.
VLV22: Aluminum core PVC insulated steel tape armored PVC sheathed power cable.
YJLV22: Aluminum core cross-linked polyethylene insulated steel tape armored polyvinyl chloride sheathed power cable.Main application scenarios:Fixed wiring power backbone lines: such as vertical backbone lines inside buildings and incoming lines to floor distribution boxes.
Long distance power transmission and distribution: such as urban power grid, rural power grid renovation in towns and villages.
Temporary power supply: such as temporary power supply for construction sites and large-scale events.
Specific industrial sectors: cost sensitive and difficult to move after installation, such as fixed lines in some factories.

Low voltage copper core cable Low voltage copper core cable refers to the wire used for transmitting and distributing electrical energy in power systems with AC rated voltage of 0.6/1kV and below (some standards can be extended to 3.6/6kV). Its conductor is made of high-purity oxygen free copper, which has excellent conductivity and stability, and is one of the most widely used and core basic materials in the field of power transmission today. Low voltage copper core cables have become an indispensable component of modern power systems due to their excellent electrical, mechanical, and safety performance. When designing and selecting, comprehensive consideration should be given to application scenarios, technical requirements, and economic benefits to choose the most suitable product, in order to ensure the long-term, stable, and efficient operation of the power system.Basic structure:Advantages of Copper Core CablesConductor:using annealed soft copper with a purity of over 99.99%, ensuring low resistance and high conductivity.Divided into single core (single strand) and multi-core (twisted). Twisted conductors have better flexibility, making them easier to bend and install.Insulation layer:PVC: commonly represented by "V" in the model. Low cost, good flame retardancy (divided into flame retardant and non flame retardant), and the most widely used.XLPE: commonly represented by "YJ" in the model. Heat resistance, mechanical strength, and chemical corrosion resistance are superior to PVC, allowing for higher operating temperatures (90 ° C).
Steel belt armor: commonly represented by "22" in the model (such as VV22), with good pressure resistance.
Steel wire armor: commonly represented by "32" in the model, it has good tensile strength and is commonly used in load-bearing situations such as vertical shafts and underwater.Outer sheath material: usually polyvinyl chloride or polyethylene, with characteristics such as weather resistance and flame retardancy.High conductivity: Copper's conductivity is second only to silver and about 1.68 times higher than aluminum. Under the same current carrying capacity, copper core cables have smaller cross-sections and are more space saving.
Low resistance and low energy consumption: Due to its low resistance, copper core cables have lower power loss (line loss) and are more energy-efficient when transmitting the same amount of electrical energy.
High strength and fatigue resistance: Copper has higher mechanical strength, good ductility, and is less prone to creep and fracture at the connection point. It has excellent connection stability and high safety and reliability.
Corrosion resistance and oxidation resistance: Copper is not easily oxidized at room temperature, has strong corrosion resistance, and has a longer service life (up to 30-40 years or even longer).
Good flexibility: With a small bending radius, it is easy to thread and lay pipes, making construction convenient.Specification
