Hot – Pluggable AMS Connectors
Specific service requirements
Design Concept
Development steps
RIBE UG / 1
AMS
• The idea is to avoid disconnectors by disconnecting
standard connectors.
• Some of the AMS connectors shall be operated under
Hot line working conditions (145kV) = „Hot pluggable“
• Other connectors to be operated without voltage
(275-400kV),
(SubCon developed a wide range of these connector types but they are not in
focus of todays presentation

AMS – Hot pluggable connector till now
• The current designs of
clamps are just combinations
of existing clamps with some
added elements to make the
parts captive
• Current practices of
operating of such connectors
are quite difficult in handling
RIBE UG / 3
All this does not take the reliability of these
contacts into consideration !
• „normal“ connectors are NOT
designed to be dismatled often
• The arc during operation might
damage the contact surfaces
• It is not possible to brush/clean the
contact surfaces of live parts of clamp
• The necessary high bolt torque
settings hardly can be applied by
isolated rods.

The technical requirement for AMS connectors
• Electrical Contact to be designed properly taking the
following into consideration to avoid Hot-spots:
- multiple operation
- low bolt forces (tightening with rods !)
- difficulties in preparation
• Ensure safe and easy handling with rods by:
- bolts with low torque settings from bottom side
- captive components
- centering help
• Controlled Arc behavior by defined arcing point
RIBE UG / 5
• We would like to take this opportunity to share our idea, to
discuss and to optimize the design.
• The straight connector presented today shall be
understand as a typical solution, the central AMS-element
of course can be applied to multiple designs and connector
arrangements according to customer demands
