Medium Voltage Switchgear Terminations
Medium Voltage screened separable connectors for switchgears. Raychem developed screened separable connectors for switchgears which are compact and space saving, having high degree of reliability and safety. These terminations are designed, developed, and tested upto 36 kV for almost all sizes of cables. Switchgear terminations are either OUTER CONE type (suitable for bushings as per EN 50181 for Type A (250 Amps), B (400 Amps), C (630/800 & 1250 Amps)) or INNER CONE type Size 2 (800 Amps) and Size 3 (1250 Amps). Screened separable connectors conform to IEEE bushings and terminations to CENELEC HD 629.1 and IS 13573-2 standards.
- Outer Cone – Angled prefabricated shielded adapter made of silicone rubber or EPDM, does not require heat during installation
- Integrated stress control Separate termination not required Stress Control – Geometrical, Refractive or Impedance type
- Test point for capacitive voltage measurement
- Mechanical lugs included
- Inner Cone – Shielded inline connection for gas insulated switchgears up to 36 kV
- Plug-in termination having geometrical stress control system is metal-enclosed, hermetically insulated and suitable for submersion or outdoor use
- Voltage detector facility available upon request
- Wedge Connector included
