Ormazabal are leading manufacturers of Medium Voltage Switchgear & Electrical Distribution Products – this includes:
The following post shows the range of Euromold Connectors which are suitable for and manufacturer approved for use with Ormazabal medium/high voltage equipment bushings according to IEC 50181. BS EN 50181:2010 is the industry standard for plug-in type bushings above 1kV up to 52kV and from 250A to 2,50kA for MV-HV switchgear and transformers.
EN 50181 IEC Bushing Types
Ormazabal recommends the use of Euromold connectors for the termination of MV-HV cables as they have been tested in the Ormazabal CGMCOSMOS system cubicles.
CGMCOSMOS is part of the Ormazabal Medium Voltage Switchgear Secondary Distribution range – a fully gas-insulated modular and compact (RMU) system up to 24kV.
3 different types of EN 50181 (IEC) bushing types that are manufactured in epoxy resin and conform to the dielectric and partial tests.
• Plug-in Bushing up to 250 A
• Plug-in Bushing up to 400 A
• Screw-in Bushing up to 630 A
MV-HV bushings are located in the cable compartment or can also be placed on the side of the cubicles for direct supply to the main busbar via plug-in or screw-in connectors rated current greater than 400A or short-circuit current equal to or higher than 16kA.
250A plug-in cable connectors (straight or elbow type for rear exit of cable) in outputs to transformer (cable compartment) for fuse protection functions and shielded connectors for circuit-breaker protection functions.
