High Voltage Switchgears

Since our mother company HyosungHeavy Industry has been developing its products and services in India from 2006 onward though various project of PGCIL and other SEBs up to 765 kV. Hyosung is the first to commission 800 kV GIS in India, over last 35 Years Hyosung supplied more than 19,000 bays across the world and over 500 Bays in India. We are the biggest GIS supplier to India and achieved new heights by
providing advance technologies to its customer globally Under 100% technology transfer on licensee agreement in the year 2016 Hyosung T&D India has started its Manufacturing in Khed City Pune to cater in India which is today supplying GIS up to 800kV to various Utilities and Industries in India. After establishment of factory in India, till date we have delivered 25*800kV GIS (PGCIL, Nijamabad, Hyderabad, NLC Ghatampur etc) and 115*145kV, 133*245 kV & 120*400kV GIS in total more than 390 bays from Indian unit

Our high voltage circuit breakers are designed in compact size and convenience for its maintenance. Its quality and reliability are also well recognized around the world as we get approved from the international certification bodies such as KERI, CESI and KEMA

HYOSUNG, pride ourselves on our ability to design and manufacture a GIS that is 100% compatible with customer existing and future needs anywhere in the world today. We design and construct a wide variety of high voltage SF6 GIS ranging from 72.5kV units to 800kV units, with short circuit ratings up to 63kA. All of our equipment complies with IEC, ANSI, IEEE and other international standards.

Features and Benefits

Compact Design

  • Can be contributed to lower down the construction costs for substation, with its smaller size of products compared to other companies.
  • Easy to build in urban region and underground area.

Superior Safety and Reliability

  • Personnel safeties are ensured by an earthed enclosure, interlocks, and lockout devices.
  • Greater stability is provided during earthquakes and the perfect enclosure protects from loss or damage from salt, dirt, lightning, and typhoon.
  • While the SF6 gas insulation prevents deterioration, the partition of the gas prevents accidents from occurring.

Designed for user convenience

  • Considering the convenience of operation and maintenance of user from product development / design.

Various Supply Records

  • Quality of the products were recognized from three-hundred customers in forty different countries around the world

Sustainable Innovation

  • Constantly developing the products to be innovative through GIS R&D center.
