Cables: Lifelines of safety

Muralidhar RaoThe wire and cable market in India was estimated at around Rs.15,000 crore in FY09. Of this, about Rs.10,000 crore belongs to the organized sector and the remaining belongs to the unorganized sector as well as the regional players. Further, the potential of the wire market industry reached around Rs.5,500 crore in FY09 and it was estimated that CAGR for the past eight years for wire & cable industry was approximately 12 per cent.

In India, overall growth of cable industry was less than 5 per cent in FY10 against the robust growth in FY09. Further, FY10 and FY11 continued to be challenging years for the industry mainly due to liquidity crunch experienced by the end-user industry sectors, in-turn leading to reduced demand and causing further delay in implementing of ongoing and new projects.

Presently, the cable market for infrastructure segment can be broadly classified as follows:
  • EHV cables ( 132kV and above )
  • MV cables ( 11kV - 66kV )
  • LV cables ( 3.3kV & 6.6kV )
  • Distribution cables ( 1.1kV )
  • Building wires
  • Specialty cables
Most prominently growing segment is that of extra high voltage and high voltage cables, which is picking up fast and is projected to double in the next three years. In addition to the projected growth in power generation and transmission, the rapid pace of urbanization is also expected to contribute to enhanced demand for underground high voltage cable installations in place of overhead lines.

In the medium and low voltage power cable field, the growth is fuelled by the boom in the realty and construction sectors in addition to power and industrial sectors.

Unfortunately, the cable industry continues to be fragmented among the organized sector and unorganized sector. There is need for consolidation and to bring in technology and quality improvements which have sometimes been sacrificed under the current intense competitive pressure and consequent low margins which are plaguing the industry. This situation is not conducive to the longterm health of the cable industry in India.

A large segment of low voltage cables is composed of building wires whose market is conservatively estimated at Rs.3,600 crore. Here, the industry is composed of a few large units with thousands of small units in the unorganized sector. In this area, there is a pressing need for upgraded wiring systems and modern manufacturing technology to cater to safety and reliability in this fast expanding market. An encouraging sign is the emergence of more discerning customers with each passing year.

Cable manufacturingWhen we talk of safety in building wires segment, the first thing that we think of is the use of halogen free wires and cables. Halogen-free wires are insulated with special insulation material which is free of halogens (namely chlorine, bromine, fluorine and iodine). These halogens when in contact with fire release huge amount of toxic smoke and corrosive acids. Sustained inhaling of these toxic smokes by individuals can lead to injury or breakdown of the nervous system, which eventually may be fatal. Thus the usage of halogen free wires and cables is the safest for human life and equipment.

Also, nowadays, we are talking more about fire survival cables particularly for high rise buildings, hotels, hospitals, etc. These cables conform to BS 6387 (fire testing standards) and should withstand 950ÂșC for three hours with CWZ fire rating. These cables are available in single core up to 300 sqmm and multi-core up to 5C 25 sqmm for both control and power applications, typically fire exhaust fans, etc. These cables are also available with shielding.

Use of quality halogen-free wires and cables and fire survival cables for building applications will certainly go a long way in reducing possibilities of fire accidents due to short circuits. Let us build a safer tomorrow through awareness and education.
