NKT Screened Connectors for Type A & B Interfaces
MV switchgear and transformer connections for 250 A and 400 A
- For interface type A & B
NKT manufactures a wide range of cables and cable accessories and is the leading supplier of medium voltage screened connectors across much of Australasia.
NKT was the first to manufacture silicone rubber cable terminations and now has 50 years’ experience, in applications up to 400 kV.
The range of screened connectors for Type A and Type B interfaces are made from silicone rubber and are quick and easy to assemble. Each connector has an outer conductive layer and an integrated inner conductive layer and field control system. Cable sheath testing can be done without dismantling the connector.
The CSE-A 250 elbow connector (illustrated) is typically used to provide a safe, screened connection up to 250A in 11/22 kV transformers, RMUs and distribution switchgear fitted with Type A bushings with plug-in Ø 7.9 mm according to EN 50180/50181. The CSE-A 250 is widely used in electricity distribution applications in New Zealand.
The CE 24-400 elbow connector and CB 36-400 T-connector provide safe, screened connections up to 400A in MV transformers, RMUs and distribution switchgear fitted with Type B bushings according to EN 50180/50181.
