Market research analysts at Technavio predict that the global overhead cable market will grow steadily during the forecast period and post a CAGR close to 6% by 2021.
This market research analysis identifies the upgrading of grid infrastructure as one of the primary growth factors for this market.
Smart grids are increasingly used in many countries as they converge analog or digital information and computer based control and automation to electricity networks.
The growth has been mainly triggered by the rising investments in smart grids due to the increasing demand for electricity.
Thus, fueling the demand for the overhead cable.
With increased adoption of smart grids, the demand for the overhead cable will rise meteorically.
The railway industry is undergoing huge amount of investments and technological advancements, which is spurring the demand for railway industry and additionally, overhead cable.
Countries with large railway networks have planned to invest huge amounts in optimizing the network, triggering more demand for power distribution cables.
This market study estimates that in terms of geographic regions, APAC will be the major revenue contributor to the market throughout the forecast period. APAC demand for overhead cable is due to factors such as growing population, rapid industrialization, urban migration, and higher living standards. Additionally, the government has privatized some sectors of the economy to increase the efficiency of the power transmission systems, inviting more investments in the T&D network globally.
The high domestic demand for electricity and the rapid rate of industrialization in developing countries in APAC have boosted manufacturing industries worldwide, which is one of the major end users in the overhead cable market.
1 AAC, AAAC, ACSR form part of the family of Overhead Cable Conductors, Transmission Conductors and Power Distribution Conductors.
These cables are formally known as All Aluminium Conductor (AAC), All Aluminium Alloy Conductor (AAAC) and Aluminium Conductor Steel Reinforced (ACSR). These overhead aluminium conductors are used as power transmission and distribution lines.
All aluminium conductors are made up of one or more strands of aluminium wire depending on the specific application.
AAC are a refined Aluminium stranded conductor with a minimum metal purity of 99.7%.
It is principally used in urban areas where spacing is short and the supports are close.
It can be used in coastal regions owing to its high degree of corrosion resistance and is also used extensively within the Railway and Metro industries.
AAAC are used as a bare conductor cable on aerial circuits that require a larger mechanical resistance than the AAC and a better corrosion resistance than the ACSR.
The sag characteristics and the strength-to-weight ratio of the AAAC conductor cable is better than both AAC and ACSR.
ACSR are available in a range of steel contents ranging from 6% to 40% for additional strength.
The higher strength ACSR conductors are commonly used for river crossings, overhead earth wires, and installations involving extra-long spans.
The ACSR conductor can, against any given resistance, be manufactured to different tensile strengths.
So a high tensile strength combined with its lightweight properties means it can cover longer distances with fewer supports.
Due to the greater diameter of the ACSR conductor, a much higher corona limit can be obtained which is advantageous on high and extra high voltage overhead lines.
