General description 

The air-insulated medium voltage switchgear of type PRO-AIR H•e•EL are used, whenever a high security of supply has to be guaranteed and also for ensuring operator safety and operating convenience. These switchgear are able to meet the specific user requirements in full and provide a satisfactory power distribution. The type PRO-AIR H•e•EL is a circuit-breaker switchgear in withdrawable-unit design. These design enables a visible isolating distance of the circuit-breaker and consequently a disconnector free design of the switchgear. The dimensions are: W x D x H: 1200 x 1500 x 2600 mm. The switchgear PRO-AIR is in the future also in more types (Transformer-, Cable-, Measuring- and riserswitchgear) available. The main dimensions are: W x D x H: 900 x 1200 x 2100 mm.The switchgear type PRO-AIR H•e•EL is delivered in the form of individual panels, where the electrical equipment (Earthing-switch, motor drive, current- and voltage transformer), panel order etc. can be determined by the customer.

 

posible fild of application

The type PRO-AIR can be used in transformer substations und substations. Possible applications: Industry, wind parks, power plants, transformer substations, aluminium- / steel works, traction power supply, electric utility, and more.
