Rated Current 1250A 1600A Gas Insulated Air Insulated High Voltage Switchgear
Product Introduction
- Air Insulated Switchgear (AIS) is a type of electrical switchgear that uses air as the main insulation medium between the live parts and earthed metal enclosure.
- It is typically used in medium voltage applications such as power distribution systems, where it is suitable for both indoor and outdoor installation.
- The switchgear consists of a metal enclosure that houses the electrical components, including the circuit breaker, disconnectors, and other protective devices.
- The live parts of the switchgear are supported by insulators and are designed to be easily accessible for maintenance and repair.
- AIS is a cost-effective solution for medium voltage applications, as it does not require the use of costly insulating materials such as oil or gas.
- The switchgear may be designed for indoor or outdoor use and may need to be rated for specific environmental conditions such as temperature, humidity, and corrosive or explosive atmospheres.
- AIS is an important component of electrical systems, providing a safe and reliable means of controlling and protecting electrical equipment and circuits. It is a proven technology that has been used for many years in a wide range of applications.
