Load Break Elbows
A load break elbow when used with a hot stick can be connected or disconnected at high voltage under load, but can only be used with up to a 250kcmil cable. At 100% insulation level, a 250kcmil is good for 345A in underground duct, so you would be de-rating your system by using a 200A elbow with a 250kcmil cable, but they are still widely used due to the flexibility given to the high voltage distribution system at the equipment. Think about it…if you had a critical application where power disruptions were extremely costly and maintenance was required on up-stream equipment in, let’s say a non critical area, this product would be great. You could disconnect the load without disturbing the critical portions, perform the maintenance and then reconnect it. Just make sure to take safety precautions, making and breaking electrical connections under load is very dangerous. The load break elbow is typically not used in man-holes, because it does not allow expansion like the dead break elbow. The construction of the load break elbow does not allow it to be connected to other elbows, but the dead break does.
Dead Break Elbows
A dead break or “hammerhead” elbow can only be disconnected when not under load, this is because you need to actually unscrew a pin to detach it. It would be pretty tough to unscrew the pin with a hot stick and the arc from the disconnected load, if under load, would be pretty substantial. A dead break elbow allows an increased current rating (up to 600A) and can be used on basically all cable types. At 100% insulation level a 750kcmil cable is rated 610A in underground duct. When would you use a 750kcmil? In most non-utility cases you would design or install sets of 500kcmil or smaller if you needed more than one 500kcmil could handle. Even from a 1200A breaker, two sets of 500kcmil per phase would be sufficient for distribution (about 1000A), if the load was even that high. Most of the time you set the relays down to the actual load in order to limit the copper used. A dead break when used in man-holes for splicing cables allows the flexibility of connecting more than two cables together as well as future expansion if required. Say another building was added that needed power, you could just connect that building to the existing array of dead break elbows. This also works great when temporary power is needed for construction or even if the circus is in town and they need medium voltage (it happens!). They can pick up power from the man-hole with the dead break elbows or from a piece of equipment with dead break elbows. I’ve heard that ships are now starting to use medium voltage shore power, I wonder what kind of connections they use.
