Aluminum conductor steel reinforced (ascr)Overhead Cable‌

Widely Use:

Power transmission:

Widely used in urban and rural power transmission networks, especially high-altitude power lines.

Industrial Park and Distribution System:

Applicable to industrial parks, commercial areas, large enterprises or other regional power systems that require power distribution.

Wind and Solar Power Projects:

In renewable energy projects such as wind power generation and solar power systems, aluminum core polyethylene insulated overhead cables also perform well.

Urban Infrastructure:

Used for power supply of infrastructure such as urban traffic lighting, telecommunications base stations, street lights, etc., to ensure the stable operation of the power system.

Advantage:

Lightweight design:

Aluminum core is much lighter than copper core cable, which reduces the weight of the cable itself, facilitates transportation and installation, and reduces construction difficulty and cost.

Good conductivity:

Aluminum conductor has good conductivity, ensuring good conductivity and low resistivity, which can effectively reduce energy loss.

Excellent weather resistance:

Polyethylene insulation material has excellent UV resistance, aging resistance and waterproof performance, suitable for use in outdoor long-term exposure environment.

High safety:

Due to the design of aluminum core cable with high tensile strength and voltage resistance, it can effectively avoid power outages caused by overload or environmental factors.

COMMON QUESTIONS

SHENXING Cable Service FAQs

Want to learn more? Check out our electrical cable most frequently asked questions.

What are the applicable occasions for aluminum core polyethylene insulated overhead cables?

Aluminum core polyethylene insulated overhead cables are suitable for overhead power lines with AC rated voltage of 35KV and below, especially in places with high safety requirements such as towns, high-rise buildings and forest areas.

What is the operating temperature limit of aluminum core polyethylene insulated overhead cables?

The long-term operating temperature of the cable, polyvinyl chloride (PVC) and polyethylene (PE) insulation should not exceed 70℃. In the case of short circuit (long duration not exceeding 5 seconds), the maximum temperature of the cable conductor shall not exceed 250℃ (cross-linked polyethylene insulation). The cable laying temperature should not be lower than -20℃.

Will the insulation layer of aluminum core polyethylene insulated overhead cables age or corrode?

Yes, the insulation layer may age or corrode due to environmental pollution, acid rain and other factors. In particular, rainwater in chemical areas may be acidic and produce an oxidation reaction with aluminum to form white powder. This type of oxide will accelerate the corrosion of the wire under the action of the electric field, reduce the strength of the wire, cause the insulation layer to swell, and even cause wire breakage.

What safety issues should be paid attention to during the installation and use of aluminum core polyethylene insulated overhead cables?

During installation and use, the following safety issues should be paid attention to:

Strictly follow the design and acceptance of regulations to ensure that the waterproof sealing work is in place to prevent water ingress and lead to corrosion of the wires.

Use special hardware for insulated wires, such as insulated wire tension clamps, puncture clamps, etc., to avoid damage to the insulation layer.

When laying cables, it should be considered that the cables and trees are kept at a certain distance to avoid frequent contact and wear of the insulation layer.

Strengthen operation monitoring, and immediately organize random inspections and treatment when abnormal phenomena such as bulging of wires are found.

What are the main causes of wire disconnection accidents of aluminum core polyethylene insulated overhead cables?

Wire disconnection accidents are mainly caused by the following reasons:

Wire breakage and falling off caused by lightning strikes.

Reduced wire strength caused by aging or corrosion of the insulation layer.

Wire damage caused by improper operation during installation and use.

How to prevent wire disconnection accidents of aluminum core polyethylene insulated overhead cables?

To prevent line disconnection accidents, the following measures can be taken:

Strengthen lightning protection of transmission lines, such as installing lightning protection devices and extending insulation creepage distance.

Develop and use water-blocking overhead insulated wires to prevent moisture from entering the wires and causing corrosion.

Strictly follow the regulations for design and acceptance to ensure installation quality.

Strengthen operation monitoring and maintenance, and promptly discover and deal with abnormal phenomena such as wire bulging.
