Surge Arresters - MV HV Medium Voltage & High Voltage 11kV 33kV 66kV
Protection of MV & HV Electrical Power, Substation, Switchgear & Transformers
Thorne & Derrick distribute the complete range of ABB Medium & High Voltage Surge Arresters (MV-HV) for the protection of MV-HV Electrical Power Systems, typically operating at 11kV/33kV and up to 66kV.
ABB provides a full range of Medium Voltage Surge Arrester, Circuit Protection & Electrical Products including fuses for the utility, industrial and commercial customers with safe, reliable and smart technologies for the distribution of electricity, typically at LV and MV voltages (11kV 33kV up to 132kV).
The extensive ABB MV Products offering includes distribution automation products, circuit protection, switching, limiting, measuring and sensing devices, switchgear, joints and terminations, modular substation packages and related services for MV electrical power systems.
Class 1, Class 2 and Class 3 type surge arresters are available in Metal Oxide or Polymeric material for the protection of MV HV networks and equipment from lightning and switching surge related overvoltages.
A Nexans Brand
Nexans Euromold 11kV 33kV 66kV surge arresters are available for the protection of medium and high voltage electricity distribution systems including transformers, switchgear, cables and separable connectors from high voltage surges – see also 132kV surge arresters for EHV and grid applications requiring protection against lightning and switching overvoltage.
Euromold 800SA Surge Arresters | a surge arrester (11kV 33kV 42kV) specified to protect MV HV cables terminated on Interface C type electrical equipment bushings into substations and connecting medium/high voltage cables.
A Pfisterer Brand
CONNEX surge arresters are used for the protection to metal-enclosed switchgears and transformers equipped with plug-in type bushings according to EN 50180 / 50181. The separable surge arrester is installed on the switchgear/transformer to prevent the intake and effects of unplanned high overvoltages.
The surge arrester limits particularly those overvoltages that are produced by the reflection of traveling waves. When using these surge arresters for switchgears/transformers connected to the transmission line via a cable route, it is necessary to protect the transition between the cable and the transmission line with suitable arresters. The capacity of protection is specially coordinated with the switchgear‘s resistance to surge voltages, considering at the same time the space arrangement and the level of electrical protection.
