The increasing popularity of gas insulated switchgear called for the development of appropriate connection systems to standardised bushings in accordance to EN50181.
Tyco Electronics Energy Division has developed two systems, one is related to the outer cone and the other one to the inner cone system. Later is used in power switch gear and power transformers.
Tyco Electronics Energy Division has several decades of experience in the field of hermetically insulated termination systems for medium voltage applications. Thus the bushings designed for gas insulated switchgear meet the standard EN50181 for connection type size 2 (800 A) and size 3 (1250 A) at operating voltage 12 kV up to 36 (42) kV.
The basic construction of the mating termination follows well known design principles and incorporates a lamellate contact system which ensures reliable current transmission via a cone clamp to the conductor. The interface between silicone body of the termination and the bushing is kept permanently sealed via the pressure of a spring between the insulator and the flange of the termination cover. The termination cover is sealed at the flange area with well known sealing methods and at the cable side with heat-shrinkable tubing against ingress of moisture.Features:
- Separable inline connection for high current, gas insulated switchgears up to 42 kV.
- Termination mates interfaces in accordance to EN50180 and EN50181 for inner cone connections.
- The contact parts are designed for stranded circular aluminium or copper conductors in accordance to IEC-60228.
