Your Professional Overhead Cable Supplier
An overhead cable refers to a transmission line erected in the air through a pole or tower, with the conductor exposed to the atmosphere and air as the main insulation medium. Compared with underground cables, its characteristics are low cost, easy maintenance, and good heat dissipation.
Application scenarios
Long distance power transmission:
High voltage/ultra-high voltage bare wires are used for cross regional power grids (such as ± 800kV ultra-high voltage direct current projects).
Rural power grid renovation:
Insulated overhead lines (ABC) replace bare wires to reduce electric shock and short circuit faults (such as in China's rural power grid renovation project).
Temporary power supply:
Light steel cored aluminum stranded wire is used for rapid installation on construction sites and in post disaster emergency situations.
New energy grid connection:
ACSR-240/40 conductors are commonly used for the collection lines of wind farms and photovoltaic power stations.

Advantages of Overhead Cables
Designed to Resist: What if a tree branch falls? Not a problem! Overhead cables with insulation are made to withstand these outside pressures and maintain power.
Space-Saving: Do you need to get electricity over difficult terrain? Overhead cables take up less space than underground alternatives and can easily traverse hills and more.
Tree-Conscious Technology: Insulated overhead cables, as opposed to their bare counterparts, can live in harmony with trees, removing the need for ongoing pruning and lowering the danger of spark-caused fires.
Easy Setup: Forget complex designs and specialist tools. Installing overhead cables is easy and requires less labour and resources, which makes it an affordable option.
Benefits of Aesthetics: Overhead cables have a more streamlined visual profile compared to large underground networks.
Safety First: These insulated cables are made to avoid unintentional touch and can even temporarily continue to give power if the suspension system fails.
Being Truthful: If someone considers illegally living off the grid, they will fail due to overhead cables. These insulated cables eliminate the chances of electricity theft.
Less is More: Insulated cables require less upkeep and evaluation, saving time and money compared to bare conductor overhead and underground systems.
Reliability: Insulated overhead cables are renowned for their exceptional dependability, minimising power interruptions.

Types Of Overhead Cable
Bare Conductor Cables
Bare conductor cables are the simplest form of overhead cables, consisting of bare metal conductors suspended from support structures such as poles or towers. These cables are typically made of aluminum or copper and are used primarily for medium to high-voltage transmission lines.
Insulated Conductor Cables
Insulated conductor cables are similar to bare conductor cables but with an added layer of insulation around the conductors. This insulation protects against environmental factors such as moisture, pollution, and wildlife interference.
Aerial Bundled Cables (ABC)
Aerial bundled cables, also known as insulated overhead cables, consist of multiple insulated conductors bundled together and supported by a single messenger wire. These cables are commonly used for low to medium-voltage distribution networks in urban and rural areas. Aerial bundled cables offer several advantages, including reduced installation time, improved safety, and enhanced reliability.
Covered Conductor Cables
Covered conductor cables feature an additional protective covering over the insulated conductors, providing enhanced mechanical and environmental protection. The covering may consist of materials such as PVC, HDPE, or XLPE, depending on the specific application requirements.
High-Temperature Low-Sag (HTLS) Conductors
HTLS conductors are designed to withstand high temperatures and minimize sagging under heavy electrical loads. These conductors typically feature a composite core made of materials such as aluminum, steel, or carbon fiber, surrounded by a layer of aluminum or aluminum alloy strands.
Selection of Cable and Structure:
It’s important to select the right type of cable for the specific application, considering factors such as the electrical load, environmental conditions, and the distance the cable needs to span.
Installation of Support Structures:
Support structures include poles, towers or pylons, which should be placed at strategic intervals to prevent excessive cable sagging, taking into account factors such as wind loads and ice buildup.
Laying and Securing Cables:
The cables are then strung and secured, maintaining an optimal balance between tension and flexibility.
Safety Compliance:
The installation process should follow industry standards and regulations to ensure safety and durability. This includes using proper insulators and hardware that can withstand environmental stresses while maintaining the integrity of the electrical connection.
Maintenance:
Regular inspection and maintenance are crucial for the longevity and safety of the overhead conductor system.
Application of Overhead Cable
Power Transmission:
High Voltage Transmission: Overhead cables are used for long-distance, high-voltage power transmission, transporting electricity from power plants to substations and end users.
Distribution Networks: In urban and rural areas, overhead cables are used in low-voltage distribution networks to supply electricity to homes and commercial users.
Communication Transmission:
Telephone and Internet: Overhead cables are used to transmit telephone and internet signals, especially in rural and remote areas.
Cable Television: Cable TV signals are also transmitted via overhead cables, covering larger areas.
Transportation:
Railway and Tram Systems: Overhead cables provide power to electrically driven trains and trams, ensuring their regular operation.
Urban Public Transit: In some cities, overhead cables are used in electric bus and tram systems.
Emergency and Temporary Power Supply:
Emergency Power Supply: After natural disasters or emergencies, overhead cables can be quickly deployed to restore power.
Temporary Power Supply: At construction sites, temporary events, and exhibitions, overhead cables provide temporary power supply.
Wind and Solar Power Generation:
Wind Farms: Overhead cables transmit electricity generated by wind turbines to the grid.
Solar Power Plants: Similarly, overhead cables are used to transmit electricity generated by solar panels.
