Question:
I’m thinking of using separable connectors for a termination, what are the pro’s and con’s of using these deadbreak connectors over traditional Heatshrink or Coldshrink terminations?
Answer:
Separable connectors, also know as screened elbows or tee connectors, offer an alternative method of terminating cable.
As with any method of cable termination there are positives and negative, as listed below:
Advantages:
– The connector is fully screened making it unaffected by adverse environmental conditions.
– The two Faraday cages featured within the connector eliminate the need for separately installed stress control and taping of components.
– Tee connectors can ‘piggybacked’, allowing more than one cable to be attached to a single bushing.
– Each unit is factory tested for partial discharge and power frequency withstand (dependant on manufacturer).
– Can be installed both indoor and outdoor environments.
– Connectors can be utilised to joint cables together, using the appropriate mating part.
Drawbacks:
– The equipment and connector must have the correct bushing interface, unlike with heat shrink and cold shrink terminations.
– Separable connectors are best suited for single core cables (Although three-core cables can be modified to suit).
– Tends to be more expensive than the equivalent cold and heat shrink terminations.
