Introduction
In the field of high or high voltage electricity transport, The driver's choice plays an essential role in the overall infrastructure performance. The market is today dominated by two types of drivers : ACSR (aluminum driver with steel soul), Renowned for its robustness, et l'ACCC / tw (Aluminum driver with composite soul with trapezoid sons), A latest generation solution offering higher energy efficiency and a significant reduction in online losses.
With the gradual modernization of electrical networks, Technical requirements are evolving : higher operating temperatures, Longer transmission distances, and increased environmental constraints. In this context, Many professionals ask themselves the same question : Should we continue to invest in traditional ACSR drivers, or opt for the increased performance of ACCC/TW drivers ?
This article presents a clear comparison between the two types of drivers, in the hope of shedding light on your technical choices.
ACSR : A classic but limited choice
The ACSR driver (Aluminium Conductor Steel Reinforced) remains one of the most used in high -voltage electricity transport. It owes its popularity to a simple and proven design, associating good conductivity and mechanical robustness.
ACSR driver structure
The ACSR driver is made up of two main elements, concentricly arranged :
A central soul in galvanized steel
Generally made up of several twisted threads, This soul provides high mechanical resistance, essential to support long litters, the weight of the cable and the loads due to the wind or frost.
Outdoor layers of aluminum wires
Wrapped around the steel core, They ensure the electrical conduction. Aluminum is light, good conductor and naturally resistant to corrosion thanks to its protective oxide layer.
Traditional ACSR advantages
This structure allows it to combine two qualities sought in air networks :
- Satisfactory electrical conductivity
- Important mechanical resistance
What's more, Steel is galvanized to avoid corrosion, and assembly in round wires makes the product easy to produce and install. ACSR therefore remains an economical solution for rural areas, mountainous or existing networks.
Technical limits of ACSR
Despite its assets, ACSR shows certain limits in modern projects :
- Operating temperature generally limited to 75–85 ° C
- Thermal sagging (arrow) more importantly important
- Current capacity limited by its structure in round threads, less dense than modern trapezoidal conceptions
- Increased risks of corrosion and long -term mechanical losses in certain extreme environments
ACSR remains a reliable solution, controlled and profitable for many standard projects. However, in a context of modernization of networks and energy optimization, It may be wise to envisage more efficient alternatives such as the ACCC/TW driver, better suited to current and future requirements.
ACCC/TW : A new generation driver
The ACCC/TW driver (Aluminium Conductor Composite Core – Trapezoidal Wire) is an innovative solution designed to meet modern energy transport challenges : Increase in load capacities, Reduction of electrical losses and limitation of the thermal arrow. Its structure differs radically from that of ACSR, both by its materials and by its geometric design.
Structure interne : An advanced composite nucleus
In the center of the ACCC/TW driver is a composite nucleus made up of carbon fibers and glass fibers, drowned in a thermo -drunk resin matrix. This material is extremely resistant to traction while being much lighter than steel. It also has a low thermal expansion coefficient, which allows Maintain a minimum arrow Even at high temperature (Until 180-200 ° C).
Conductive layers : aluminum trapezoidal threads
Around the composite nucleus are wound aluminum wires trapezoidal in shape, Rather than round as in classic ACSRs. This geometry allows better compactness of the driver, by reducing empty spaces between the wires. Result : A higher driver section with equivalent diameter, which significantly improves current transport capacity.
Depending on the versions, aluminum used may be thermoremoric alloy (type Al-Zr), offering better resistance to high temperatures and an increased lifespan.
Other technical characteristics
- Reduction of losses by joule effect thanks to lower resistance.
- Less thermal sagging, which keeps a ground clearance sufficient without enhance the pylons.
- Compatible with existing infrastructure, replacing an ACSR with an ACCC/TW can often be done without modifying the supports.
Thanks to these characteristics, The ACCC/TW driver is today favored in many projects where energy efficiency, The modernization of lines and long -term reliability are priority.
Technical comparison : ACCC/TW vs ACSR
To fully understand the potential advantages of ACCC/TW compared to ACSR, It is essential to analyze their technical characteristics comparatively. Here are the main points of differentiation between these two types of conductors :
As this painting shows, ACSR remains a reliable solution for many standard projects. But in a context of energy transition, performance optimization and cost reduction over the long term, ACCC/TW offers significant technical profits.
Concrete advantages of ACCC/TW in your projects
The ACCC/TW driver is not just a technical alternative to the model ACSR : It is a strategic solution adapted to modern networks that are looking for performance, long -term economic sustainability and economic optimization. Here are the main advantages that make it an increasingly privileged choice on an international scale :
More power, without modifying the infrastructure
Thanks to its compact design (trapezoid) and its ultra-light composite core, the ACCC/TW makes it possible to double the current capacity compared to an equivalent ACSR, without changing the existing pylons.
Excellent resistance to high temperatures
With a service temperature up to 200 ° C, This driver keeps a minimum arrow even in the event of thermal overload, which is particularly useful in areas with high climatic variations (deserts, tropics, mountains).
Significant reduction in energy losses
The lower electrical resistance reduces losses by joule effect up to 40%, contributing to immediate and continuous energy savings.
Ideal for extreme environments
The carbon and glass fiber nucleus resists corrosion, almost not expands, And stay stable in front of the wind, with saline humidity, chemical or frost agents. It adapts perfectly to coastal areas, industrial or isolated.
Less maintenance, more reliability
Thanks to its composite materials and its stable behavior, ACCC/TW requires less maintenance, limits the interruptions and lengthening the lifespan of the facilities, thus reducing the overall cost of possession.
