Two ranges of high voltage cable couplers are offered:  3 inch for 3,3 to 6,600 Volt and 4 inch for 6,6 and 15,000 Volt applications.  The 4 inch couplers can be offered in single key and double key configurations to allow, for example, 6,6 kV and 11,0 kV cables to be used in the same pit without the possibility of incorrect couplings occurring.  All couplers are of the quick-release type which facilitates coupling and uncoupling by one man.  The couplers can be padlocked for safety reasons.

One in one out, one in two out and one in three out Janus boxes can be supplied with the same features of quick connect, single or double key and padlocking.

Quick thread couplers can be supplied for the unconverted.

Low voltage flame proof couplers for underground use can also be supplied.
