Our company manufactures the UniSec series of Certified Medium Voltage switchgear, under licence from ABB.
UniSec is the new ABB air-insulated switchgear, LSC2A-PM for panels with switch-disconnector, LSC2B-PM for panels with withdrawable circuit-breaker up to 17,5kV and LSC2B-PI up to 24kV.In accordance with the loss of service continuity definitions and standard IEC 62271-200.UniSec offers these features:
-Air insulation of all live parts
-Removable and withdrawable vacuum and SF6 circuit-breakers-Withdrawable vacuum contactor
-LSC2A service continuity classification
-Withdraw able circuit-breaker and contactor class LSC2B service continuity classification
-Complete range of fuctional units and accessories-Large selection of state-of-the-art protection relays, intergrated on removable circuit-breakers or separately mounted for protection, control and measurement fuctions.
The UniSec range is fully designed and type tested according to the IEC standard no.62271-200, and has a high internal arc withstand ability rating.
Senekis through a license agreement with ABB Technology LTD Zurich Switzerland holds the license to manufacture, sell and use the marks of Air-Insulated Medium Voltage switchgear typt UniSec,using drawings and components of ABB.
The switchgear comply with IEC62271-1 and IEC/EN 62271-200 standards and are covered by the relevant type tests performed.
Senekis guaranties the safety, performance and quality of the licensed products and submits all products in a series of routine verification tests according to the European Standard IEC/EN-62271-200.
DocumentationWe manufacture and deliver our Medium Voltage products with integrated electrical diagrams, and we issue routine verification test reports which are handed with our products.
