In addition to our product technology, Hitachi ABB Power Grids proudly stands with our customers via our global Service organization. Hitachi ABB Power Grids offers significant risk management opportunities, in order to reduce our customers project risk profile. As the industry uncovers more challenges with air gear, it’s a good time to take a look at a new solution that delivers higher … IEC air insulated switchgear UniGear ZS1 Medium voltage switchgear for primary distribution up to 24 kV suitable for indoor installations UniGear ZS1 is the ABB mainline switchgear for primary distribution up to 24 kV, 4 000 A, 63 kA. A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. The global electricity demand rose by 4% in 2018, growing nearly twice as fast as the overall demand for energy. HIS – the gas-insulated switchgear for indoor and outdoor use needs less than half of the space of a comparable air-insulated substation. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). Technavio's analysts forecast the global air insulated switchgear to grow at a CAGR of 7.05% during the period 2019-2023. Air-insulated switchgear for primary distribution NXAIR is a metal-enclosed, factory-assembled and type-tested medium voltage switchgear according to IEC 62271-200 for indoor application up to 36 kV. Air insulated Medium Voltage Metal clad switchgear, as with ANSI/ IEEE C37.20.2 Rated Voltage: 4.76 KV/8.2 KV/15KV Main Bus current Ratings : (1200/2000/3000/3500)A and 4000A Forced Cooling It uses air as a insulating material. For arc-resistant applications, ABB’s famous SafeGear® line features ratings up to 4000 A, 63 kA at 5 and 15 kV with the smallest footprint available in the industry. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6 ). The 8DQ1-type HIS is a compact switchgear solution for a rated voltage of up to 550 kV. When we talk about ownership, it talks about the total cost of having the equipment.

Air Insulated Switchgear NXAirS 40.5kV 3 Typical uses Classification NXAirS 40.5kV withdrawable metal - enclosed medium voltage switchgear is used in substation and power distribution system, mainly for primary power distribution system: Air insulated switchgear (AIS) adopts the air as the insulation media designed voltage ranging from 11KV to 36KV medium voltage power distribution system. On a deep level comparison, you need to weigh the upfront expenses of GIS an AIS against the needed lifelong maintenance. It uses air as the primary dielectric from phase-to-phase and phase-to-ground insulation. The VH-AIS range of switchgear has a metal clad design, and its robust construction ensures it functions well even in adverse environment conditions. Indoor Substation type is only employed in places where high pollution or saline environment exists. The UniGear family of IEC switchgear and motor control centers for primary distribution offer a unique opportunity by freely combining different types of panels (UniGear ZS1, UniGear 550, UniGear 500R and UniGear MCC) in to the same switchgear, giving the highest flexibility while optimizing footprint.
