Asea Brown Boveri Limited NIT, Faridabad, Haryana

We are offering surge arresters. Safe and reliable protection of electrical equipment abb surge arresters are the primary protection against atmospheric and switching over voltages. Abb offers a complete range of surge arresters for high, medium and low voltage applications. The range comprises of ac and dc solutions up to 1,100kv and arresters for special applications like railways, dc-voltage limiting devices and many other purposes. The designs comply with the iec 60099-4 and ansiieeec62.11.

We are offering silicon surge voltage suppressor. Transient voltage suppressors are effective protection devices against repetitive and non-repetitive over voltages caused by events like electrostatic discharging or during inductive switching. They have symmetric blocking characteristics with avalanche breakdown capability. The 5ssa and 5ssb silicon surge voltage suppressors are best suited for power thyristors, transistors and igbts (insulated-gate bipolar transistors) against small and medium power surges (eg 200 kw over 10 microseconds). They allow to use thyristors with lower voltage capabilities and much smaller snubber circuits. 5ssa and 5ssb silicon surge voltage suppressors consist of a diffused pnp-si-wafer mounted with pressure contact in a hermetically sealed metal-ceramic-package.

We are offering power transformers. Abb's power transformers are key components in power networks. Their availability and longevity have a major impact on grid reliability and profitability. Abb does not compromise on quality. We ensure that every one of our 14,500 delivered units has undergone rigorous full-acceptance testing. Abb offers a complete range of power transformers and related components and parts. We have delivered more than 14,500 power transformers (over 17,000,000 mva), including over twenty 800 kv uhvdc and over five hundred 735 - 765 kv ac units, to all major global markets. Our entire range is the result of our own research, development and manufacturing, which makes us unique in the industry. This has given us extensive experience in every relevant part of power transformer technology. Customers worldwide can securely rely on the quality and reliability of our products

We are offering hybrid switchgear pass for 72.5 to 420 kv compact switchgear fully assembled and high-voltage tested in factory, for rapid installation and energization pass (plug and switch system) encloses all functions of a complete switchgear bay in a single module. The hybrid design makes use of traditional air-insulated busbars to connect with other equipment in the substation while enclosing the following bay functions in a single-phase gas-insulated housing. circuit breaker combined disconnector and earthing switches voltage transformers and voltage sensors current transformers fast earthing switch options

We are offering hvdc extruded cables. Power transmission systems with capacities up to 1,200 mw in the mid-1990s, abb became the first company to develop, produce and install a complete high-voltage direct current (hvdc) extruded cable system. These transmissions benefit not only from the high-voltage cable, but also the type of converters used at either end of the cable system. The voltage sourced converter (vsc) technology used in these installations is ideal for connecting weak power networks, and ensures proper voltage, power and short circuit control.

We are a major supplier of brushless synchronous generators for diesel and gas engines. These are in use all over the world, producing power in electric utilities and district heating plants, industrial plants, the marine and offshore sectors, and similar applications. In every case we work with our customers, using our application-specific know-how to ensure that your specific needs are met. Our products are designed to provide high levels of efficiency over a long service life with low overall life cycle costs, up to 90% of the parts of the product can be recycled.

We are offering gas insulated switchgear. Gas-insulated high-voltage switchgear (gis) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. Gis is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial plants and hydro power plants. Abb has always been and continues to drive innovation in gis technology in ratings, operations, switching technology, smart control and supervision, and compactness. As a result, abb’s gis offers outstanding reliability, operational safety and environmental compatibility. It provides a complete range of products for all ratings and applications from 72.5 kv to 1200 kv matching current and future requirements for modern switchgears.

We are offering fast thyristor for applications with frequencies higher than the domestic ac mains supply (e.g. 50 hz or 60 hz), thyristors with lower values of tq are required. Fast thyristors have optimized turn-off parameters and are designed for general power switching applications.

We are offering application steel strips the em stabilizer is a new product in our em product family to ensure better quality of steel strips. The em stabilizer system is the latest development in the em product family. It features: improved quality increased line speed improved work environment cost savings

We are offering air insulated switchgear. Complete portfolio for all applications and environments abb focuses on the continual development of new technologies to increase the eco-efficiency, availability and reliability of ais substations products and have a century of practical experience to rely on. Ais primary substation equipment contains of a portfolio up to 1200 kv including live tank circuit breakers(ltb), dead tank circuit breakers (dtb), instrument transformers, disconnectors, surge arresters, monitoring and controlled switching. In addition to our product technology, abb proudly stands with our customers via our global service organisation. abb offers significant risk management opportunities, in order to reduce our customers project risk profile. we are your partner in the project, with unsurpassed experience, to ensure you reach your milestones.
