Product Description

UniGear ZS2 Description

 

• Each UniGear ZS2 panel consists of a single unit which can be equipped with a circuit-breaker, withdrawable fused device, off load disconnector, as well as with all the accessories available for conventional switchgear units.
• The panel incorporates a compartment in its upper level to house the auxiliary instrumentation.
• Full conformity with IEC standards
• Highest level of operator safety with front, lateral and rear arc protection
• Space saving by wall standing solution
• Economic in civil works and transportation thanks to compact dimensions
• Robust design for highest availability and low maintenance
• Long life expectation thanks to use of AluZink sheet steel without welding points
• Units can be coupled together directly with double busbar units, with the possibility for further extension on both sides of the switchgear.
• The switchgear does not require rear access for installation or maintenance.
• All the service operations are carried out from the front.
• Metal clad, partition PM, service continuity LSC 2B
• Internal arc proof 31.5 kA 1 s, AFLR
• Cassette or floor rolling type withdrawable circuit breaker options
• Fully interchangeable vacuum and SF6 gas circuit breaker
• Indoor installation
• Operational safety, circuit-breaker racking in / out with door closed
• Motorized racking in / out of cassette type circuit breaker
• Earthing switch with making capacity

UniGear ZS2 is the mainline

• switchgear for primary distribution up to 36 kV, 3150 A, 31.5 kA.
• The switchgear is manufactured worldwide and there are more than 20000 panels currently installed.
• UniGear ZS2 is used to distribute electric power in a variety of demanding applications such as in utility substations, power plants or chemical plants.
