Medium Voltage Cable Terminations

Termination, medium voltage cables, distribution networks, Electrical,

Terminating medium voltage cables in electrical distribution networks is critical in order to provide safety for operations personnel, and to provide the expected reliability of the electrical distribution network. Terminations for medium voltage applications come in two general types.

Live-front terminations:

  • Simplest of connections, but with tradeoffs
  • Live conductor is exposed and could create lower safety for the public and for operations personnel.
  • Susceptible to environmental influences, such as animal ingress, that results in less than optimal reliability for the distribution network.

Dead-front style terminations:

  • Live conductor is completely encased within an insulation material.
  • The exterior of the termination is fully shielded and operates at electrical ground potential.
  • This ground-potential operating environment provides for operational safety as well as makes the terminations resistant to failures from environmental conditions.


Common Dead-front termination types:


200A dead-front terminations (Load break elbows):


  • Designed for live-break/live-make operation. Not that many qualified operators use this feature, as it would generally require an energized work permit.
  • Little know safety feature: Designed so that if the elbow is plugged into a fault (over-current event), by mistake (no one would ever do that on purpose), the termination will be forced out of the apparatus bushing and quench the arc. This protects the operator from potential arc-flash injury.
  • Capacitive test point that allows the operator to check for the presence of voltage prior to interacting with the termination (load break elbow).


600A dead-front terminations (Dead-break T-bodies):

  • Designed for de-energized operation only.Dead-break T-bodies, terminations, electrical terminations
  • Higher continuous current operation dictates a better connection and these are therefore a bolted connection.
  • Terminations can be stacked on the apparatus bushing, allow for cable splicing or adding protective equipment, such as surge arresters, to the apparatus.
