Medium Voltage(1/35KV) Power Cable-YJLY32
YJLY32 cable uses aluminum conductors, which are light and cost-effective. The cross-linked polyethylene insulation layer gives the cable excellent electrical properties and heat resistance, and the long-term operating temperature can reach 90°C. The fine steel wire armor layer provides excellent mechanical protection, enabling the cable to withstand external mechanical stress and tension. The outer PVC sheath enhances the cable's weather resistance and chemical corrosion resistance, ensuring its stable operation under various environmental conditions.

BS EN 60228:Specifies the structural and performance requirements for cable conductors, ensuring that the electrical and mechanical properties of the conductors meet international standards.
GB/T 12706.2:Chinese national standard, covering cross-linked polyethylene insulated power cables with rated voltages from 6kV to 35kV, ensuring the applicability and safety of the product in the domestic market.
UL 1581:Cable fire resistance and weather resistance standard, verifying the performance of the cable in high temperature and harsh environments, ensuring its reliability under various conditions.
Application areas:
Power grid transmission and distribution: construction and transformation of medium-voltage power networks in cities and rural areas
Industrial power distribution: power transmission for factories, mines, petrochemicals and other industries
Infrastructure projects: large projects such as high-speed railways, subways, airports, power stations, etc.
Renewable energy: power transmission for new energy power stations such as wind power and photovoltaics
Underground and underwater laying: suitable for direct burial, pipeline laying or underwater laying
Advantages
Lightweight and efficient, reducing installation costs
Compared with copper core cables, aluminum core cables are lighter, easier to transport and install, and reduce the burden on cable trays and support systems, thereby reducing the overall construction cost.
Excellent electrical performance
YJLY32 uses high-purity aluminum conductors with a resistivity as low as **≤0.028 Ω·mm²/m**, which can effectively reduce power loss and ensure stable power transmission.
Excellent mechanical strength and durability
Steel wire armor enhances the cable's ability to resist mechanical damage, making it suitable for harsh environments such as underground laying and pipeline laying.
High temperature resistance and aging resistance
XLPE insulation layer supports a long-term operating temperature of 90°C and can withstand a short-circuit temperature of up to 250°C for a short time (within 5 seconds), with excellent heat resistance and aging resistance.
Corrosion resistance, suitable for complex environments
YJLY32 outer sheath uses high-density polyethylene (PE), which has good corrosion resistance, moisture resistance, acid and alkali resistance, and is suitable for hot and humid areas or environments with chemical corrosion.

COMMON QUESTIONS
SHENXING Cable Service FAQs
Want to learn more? Check out our electrical cable most frequently asked questions.
What applications is this cable suitable for?
This cable is mainly suitable for underground power transmission, industrial power distribution, construction projects and energy facilities, especially in environments that require protection and resistance to mechanical damage.
What is the maximum operating temperature of this cable?
The maximum operating temperature of the cable conductor is 70℃, and the maximum temperature of the conductor can reach 160℃ during short circuit, but the duration shall not exceed 5 seconds.
Can this cable be installed in extreme climate conditions?
Yes, the minimum installation and laying temperature of the cable is 0℃. Therefore, it can be installed in low temperature environments, but special protection measures are required when installed in extremely cold environments.
Can the cable be used in water or humid environments?
Yes, the cable has a PVC sheath and steel belt armor, which is waterproof and moisture-proof, and is suitable for buried or humid environments, such as underground cable ducts or moist soil.
What are the temperature requirements for laying the cable in the air and underground?
When laying in the air, the recommended ambient temperature is 40℃; when buried in the soil, the ambient temperature should be 25℃ to ensure the best working performance of the cable.
What are the advantages of using aluminum core instead of copper core?
Aluminum core cable is lighter and less expensive than copper core, suitable for long-distance power transmission projects, and can also meet most industrial and commercial uses in terms of conductivity.
