Cu(Al)/XLPE/PE 6-35kV Power Cable

The maximum allowable operating temperature of the conductor within medium voltage power cable, specifically those rated for 6-35kV, is 90℃. This temperature threshold ensures optimal performance and safety during continuous operation, preventing overheating and potential damage to the cable insulation and conductor material. For Aluminum Alloy Power Cable and Building Wire, which may also operate within this voltage range, the same temperature limit applies, guaranteeing reliable power transmission and distribution.

In addition to the maximum operating temperature, the maximum short-circuit temperature of the conductor within these cables shall not exceed 250℃, with a maximum duration of 5 seconds. This high-temperature tolerance during short-circuit events is crucial for protecting the cable from immediate thermal damage and ensuring the system's ability to withstand temporary fault conditions. For Medium Voltage Power Cables used in industrial or commercial settings, where short-circuit risks may be higher, this specification is particularly important. Similarly, Aluminum Alloy Power Cables and Building wires, often found in residential and commercial construction, benefit from this robust short-circuit temperature rating.

Moreover, the ambient temperature should not be lower than 0℃ when laying these cables. This minimum ambient temperature requirement ensures that the cables maintain their flexibility and ease of installation without risking brittle or damaged insulation materials. For Medium Voltage Power Cables installed in outdoor environments or underground conduits, seasonal temperature fluctuations must be carefully considered to avoid laying cables during excessively cold conditions. Aluminum Alloy Power Cables and Building wires, often installed in buildings under construction, should also adhere to this ambient temperature guideline to prevent installation issues related to cold brittleness.

In summary, the specified maximum allowable operating temperature of 90℃, maximum short-circuit temperature of 250℃ (5s maximum duration), and minimum ambient temperature of 0℃ during cable laying are essential parameters for ensuring the reliability and durability of Medium Voltage Power Cables 6-35kV, Aluminum Alloy Power Cables, and Building wires across various applications and environments. By adhering to these temperature specifications, installers and engineers can ensure safe, efficient, and long-lasting power distribution systems.
