General description

the air-insulated medium voltage switchgear of type Pro-Air H.e.EL are used, whenever a highsecurity of supply has to be guaranteed and also for ensuring operator safety and operating convenience. These switchgearare 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 enablesa 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 electricalequipment (Earthing-switch, motor drive, current- and voltage transformer), panel order etc. can be determined bythe customer.
