Aluminum Alloy Cable

Detail of Aluminum Alloy Cable

Load-bearing and Self-Weight

Aluminum alloy improves the tensile strength of pure aluminum. Aluminum alloy cables can support the self-weight of 4000 meters in length, while copper cables can only support 2850 meters. This advantage is particularly prominent in large-span building wiring.

Application Scope

The cross-linked polyethylene insulated power cable consists of a tightly pressed aluminum alloy conductor, inner shield, insulation layer, outer shield, and sheath. Among them, cross-linked polyethylene is obtained by using chemical or physical methods to transform the linear structure of polyethylene into a three-dimensional network structure, which not only converts thermoplastic polyethylene into thermosetting cross-linked polyethylene, thereby significantly improving its mechanical properties, thermal aging performance, and environmental application capabilities, but also maintains excellent electrical properties.

The cable design complies with national standard GB/T12706-2008 and the recommended international electrical engineering standard IEC60502. The normal operating temperature of the cross-linked polyethylene insulated cable conductor is 90°C, and the cross-linked polyethylene cable not only has excellent electrical performance, but also has the advantages of a simple structure, small outer diameter, light weight, convenient use, and no limit on the laying drop height.

Operating Conditions

1. The higher rated temperature of the cable conductor is 90°C, the emergency overload temperature is 130°C, and the temperature does not exceed 250°C when the conductor shorts (for a longer duration of 5 seconds).

2. The laying temperature shall not be lower than 0°C, and the cable drop height is not restricted.

3. The specified bending radius is as follows:

Single core: 10(d + D) ± 5%

Three cores: 7(d + D) ± 5%

(Where D is the actual outer diameter of the cable, and d is the actual outer diameter of the conductor)

4. The operating temperature of the cable:

Polyvinyl chloride sheath does not exceed 90°C; polyethylene sheath does not exceed 80°C.

5. It is only used in dry or humid environments, with an environmental working temperature of 75°C.

According to user requirements, high-temperature or low-temperature resistant cables can be produced.

6. One or two single-core cables are not allowed to be laid in iron pipes.
