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.
