Acting on climate
Helping Modernize India’s Rail System
India’s railways are responsible for 4% of the country’s total greenhouse gas emissions. The government plans to have India’s railways routes fully electrified by 2023 and fully powered by renewable sources by 2030. As a result of this shift, 6.8 million tons of CO2 will be eliminated annually.
DuPont’s Interconnect Solutions plays a critical role in India’s rail electrification as the sole supplier of wire insulation for their Electric Locomotive traction motors. The advanced traction motor design boosts India Rail’s hauling capacity by 50%, saves energy and reduces costs and GHG emissions.
The traction motors that power today’s latest generation electric locomotives must deliver long-term reliable operations with improved safety margins in a variety of demanding situations and environments conditions.
Insulation around the wire of an electric motor is subject to high electrical and thermal stresses while operating. Specifications require that the insulation protects effectively at temperatures above 200o C when in continuous use.
DuPont Kapton® polyimide films are used to insulate traditional wire designs and have been the high-temperature industry standard for over 50 years.
DuPont’s latest innovation, Kapton® FCRC polyimide film insulation, takes performance to the next level by meeting the aggressive voltage switching demands of today’s silicon carbide variable frequency drives. In addition, Kapton® FCRC wire insulation is coupled with DuPont Nomex® slot liner to set the insulation standard for these latest motor designs.

The Indian government plans to have India’s railways routes fully electrified by 2023 and fully powered by renewable sources by 2030. DuPont Kapton® FCRC wire insulation coupled with DuPont Nomex® slot liner insulation is the standard for high efficiency traction motor insulation systems for demanding, high temperature rail applications,
Photovoltaic panels are expected to convert sunlight into energy for 30 years or more, but solar panels in the field often experience degradation and other failures that shorten their useful life, thereby reducing their ability to produce renewable energy. Tedlar-based backsheets have been demonstrated to significantly extend panel lifespan, with multiple examples of installations generating electricity well beyond 30 years.
In August 2021, Hurricane Ida significantly impacted our Pontchartrain, LA manufacturing facility. Preparations for site operations, employee safety and community recovery began days ahead and continued weeks after.
Hydrofluorocarbons (HFC) are used in blowing agents and manufacturing of other building insulation materials. Some HFCs have high global warming potential (GWP) where they end up in the atmosphere and contribute to climate change.
Creating a water-optimized future relies on innovation and action now, and in future generations.
The “Flow of Life” project promotes water science literacy and education across primary and secondary students in China.
Many rivers around the world are now classified as “high stress”. This means that more than 40% of the naturally available water in the basin is removed leading to the risk of water scarcity. Our Zhangjiagang site in China set a sustainability goal to reduce wastewater generation, and address other water usage opportunities.
