Aluminum Overhead 1 Core ABC Cable Alu Pre Assemble 3x50mm² Low Voltage

1. Product Overview

The 1 Core/Multi-Core Aluminum Overhead Cable Alu Pre Assemble 3x50 Mm2 is a high-quality electrical cable designed for overhead power transmission applications. It is constructed with aluminum conductors, which offer several advantages such as good conductivity, light weight, and cost-effectiveness. This cable is pre-assembled for ease of installation and comes in a configuration of 3 cores with a cross-sectional area of 50 square millimeters each.

2. Core Structure

• The cable consists of either a single core or multiple cores, depending on the specific application requirements. In the case of the 3x50 Mm2 version, it has three cores.

• Each core is made of high-purity aluminum, which ensures efficient electrical conduction. The aluminum is typically stranded to increase flexibility and durability. The stranded structure also helps to reduce the risk of breakage during installation and in service.

3. Insulation Material

• The cable is insulated with a suitable insulating material that provides excellent electrical insulation properties and resistance to environmental factors. Commonly used insulation materials for overhead cables include polyethylene (PE) or cross-linked polyethylene (XLPE).

• These materials offer good dielectric strength, low leakage current, and resistance to moisture, UV radiation, and chemical substances. They ensure the safety and reliability of the cable's operation, even in harsh outdoor conditions.

4. Sheath

• Over the insulation layer, a sheath is provided to protect the cable from mechanical damage, abrasion, and environmental influences. The sheath is usually made of a durable polymer material such as polyvinyl chloride (PVC) or polyethylene terephthalate (PET).

• The sheath provides additional mechanical strength and resistance to corrosion, making the cable suitable for use in a variety of outdoor environments. It also helps to maintain the integrity of the insulation and the overall cable structure.

5. Advantages

(1) Lightweight

• The use of aluminum as the conductor material makes the cable relatively lightweight compared to copper cables of the same cross-sectional area. This characteristic simplifies installation procedures as it requires less effort and equipment for handling and installation. It also reduces the load on supporting structures such as poles and towers.

(2) Good Conductivity

• Aluminum has a reasonably good electrical conductivity, which allows for efficient power transmission. Although it is slightly lower than that of copper, the cost advantage and lightweight nature of aluminum make it a popular choice for many overhead power distribution applications. The 3x50 Mm2 configuration provides an appropriate balance between conductivity and current-carrying capacity to meet the requirements of most medium-voltage power transmission systems.

(3) Cost-Effective

• Aluminum is generally more abundant and less expensive than copper, making the 1 Core/Multi-Core Aluminum Overhead Cable Alu Pre Assemble 3x50 Mm2 a cost-effective solution for power transmission projects. It offers a lower initial investment cost without compromising significantly on the performance and reliability of the cable. This makes it an attractive option for utility companies, contractors, and developers looking to optimize their project budgets.

(4) Easy Installation

• The pre-assembled design of the cable saves time and effort during installation. The cable comes with all the necessary components and connections already in place, reducing the complexity of the installation process. It also minimizes the risk of installation errors, ensuring a smooth and efficient installation operation. Additionally, the flexibility of the cable due to the stranded core structure allows for easy routing and bending around obstacles, further facilitating the installation process.

(5) Durability

• The combination of high-quality materials used for the insulation and sheath, along with the robust construction of the cable, provides excellent durability. The cable is designed to withstand harsh environmental conditions such as temperature variations, humidity, UV radiation, and mechanical stress. It has a long service life, reducing the need for frequent replacements and maintenance, which in turn lowers the overall lifecycle cost of the power transmission system.

6. Applications

• The 1 Core/Multi-Core Aluminum Overhead Cable Alu Pre Assemble 3x50 Mm2 is widely used in various overhead power transmission and distribution systems. It is suitable for medium-voltage applications in urban and rural areas, including power supply to residential areas, commercial buildings, industrial parks, and agricultural facilities.

• It can be used for connecting substations to distribution points, as well as for distributing power within a local power grid. The cable is also commonly used in rural electrification projects and in areas where cost-effectiveness and ease of installation are important considerations.
