New Delhi: Public sector utility Bharat Heavy Electricals (BHEL) has said that it has become the sole supplier of disc insulators for high voltage transmission projects.
The company said in a statement that it would supply disc insulators for 800kV High Voltage Direct Current (HVDC) Transmission Lines.
Insulators are essential requirements for smooth transmission.
BHEL has designed, developed and tested these insulators at Sweden, the only internationally accredited laboratory equipped for testing of such insulators in the world.
These insulators have a special material composition to perform reliably under HVDC voltages and are also required to have different profiles to perform well under polluted conditions, which is one of the most critical requirements of HVDC applications.
These insulators would be used in the first-ever 800 kV HVDC Transmission Line of state-run PowerGrid Corporation Ltd from Biswanath Chiryaly in the North East to Agra.
The interconnection is expected to bring surplus, low-cost power from the North Eastern India to the power deficit states in the Northern region.
BHEL has also established HVDC technology for efficient and reliable transmission of bulk power over long distances. It has also successfully upgraded the country’s first National HVDC transmission project between Barsoor in Madhya Pradesh and Lower Sileru in Andhra Pradesh.
In the overseas market, BHEL has exported ceramic insulators to several countries including UK, Turkey, Egypt, Malaysia, Ghana, UAE, Saudi Arabia, Nepal and Trinidad & Tobago.
