Air Insulated Switchgear


Air Insulated Switchgear (AIS) is a kind of medium and high voltage switchgear. They can handle higher currents and voltages, providing reliable power transmission and distribution capabilities. It is mainly used for circuit breaking, grounding and isolation operations in power transmission and distribution systems to ensure the safe and reliable operation of the power system.

Reliability:  AIS adopts a simple design and reliable air insulation, which can provide stable power transmission and distribution functions under various environmental conditions. They have been fully tested and validated, and have high reliability and durability.

Safety:  AIS emphasizes safety in its design and can effectively isolate errors and abnormal situations in the power system. They have good electrical isolation capability and can protect operators and equipment from hazards such as electric shock or short circuit.

Adaptability:  AIS can be customized and configured according to different distribution requirements. They provide various rated voltage and current options to adapt to different scales and types of power systems.

Easy to Maintain:  AIS uses air as the insulation medium, making maintenance and repair easier and more convenient compared to other insulation materials. Maintenance personnel can easily inspect and maintain the equipment, reducing downtime and costs.

Cost Effectiveness:  Compared to other types of insulated switchgear, AIS typically has lower manufacturing and installation costs. They adopt simplified designs and common materials, suitable for large-scale production and standardized applications.

As professional MV switchgear manufacturer, we provide fully customization service according to the customer’s local requirements, electricity standards, environments, climates and so on. The followings are supported for customization:

Rated Voltage:  According to the customer’s local electricity standard, we support various the option of adapting the rated voltage. Common rated voltage includes 3.6kV, 7.2kV, 11kV, 12kV, 17.5kV, 22kV, 24kV, 33kV, 36kV, etc., depending on the requirements of the local power supply standard.

Rated Current:  According to the customer’s load demand and power system capacity, we provide suitable rated current options. Common rated current options include 630A, 1250A, 2000A, etc.

Environmental Adaptation Solution:  According to the environmental conditions of the customer’s location, the corresponding protection solution is provided for high temperature, humidity, high salinity, high corrosion and other harsh environments to ensure stable operation of the equipment.

Short-Circuit Withstand Capability:  According to the short-circuit current level of the power system in the customer’s location, we provide the corresponding short-circuit withstand capability options. This usually involves the rated short time withstand current and the rated peak withstand current of the equipment.

Operation Method:  According to the customer’s needs, we provide the appropriate operation method options, such as manual operation, remote control operation, automated operation, etc. 

Wiring Method:  According to the customer’s local power system requirements and distribution layout, we provide suitable wiring method options, such as top incoming, bottom incoming, side incoming, etc.

Control and Protection System:  According to the customer’s requirements, we provide suitable control and protection system options, such as telemetry and telecontrol, fault alarm, protection relay, etc.

Equipment Size and Installation Method:  According to the conditions of the customer’s site, we provide suitable equipment size and installation method options to ensure that the switchgear can adapt to the existing layout and installation requirements.
