Transfer elements
Ensures the passage of the trolley between discontinuous sections.
Description
The purpose of the transfer elements is to ensure the trolley crosses over mechanically discontinuous line sections, for instance as
in the case of switches. They can also be used for circuit interruptions (the advantage being that they actually cut the electrical
circuit). However, transfer elements should in no case be used as electrical switches since they are not designed to resist electric
arcing. Two types of transfer elements are offered: short transfer elements with short cones must be used when the facing cones
are very close to each other with a minimum clearance of 10 mm and maximum clearance of 30 mm. Beyond that, use transfer
elements with long cone. Safety: The contact with the protective earth conductor has priority over the other poles. The transfer
element design does not allow access to the live parts, even from the front of the cone, due to the built-in insulators and safety
distances. The transfer elements have a protection index of IP23 taking access to the dangerous parts into consideration, but do not
offer any protection against solid foreign bodies (Ø12.5 ball test according to EN60529). Operator protection against access to the
live brushes on the trolley and against the risk of mechanical blockages when crossing the interval between transfer elements must
be provided by the customer. As the transfer elements are subjected to line expansion efforts, ME1500 fixed hangers must always
be used together with rigid brackets such as ME1760 or ME1780, or welded brackets, for example. Furthermore, fixed hangers allow
the transfer elements to withstand the stress caused by moving trolleys. The use of a special trolley for transfer element and/or of a
special carrier for transfer element may be required, because of the dead length of the transfer elements and their geometry.
Expansion joints can also be necessary beyond a certain distance between 2 transfer elements of the same line sector.

The transfer elements are pre-mounted on line elements. The total length is 1 metre in the standard version, but special lengths are
available on request. A transfer element with the earth on the right is identified by facing the transfer guide, with the opening at the
bottom, when the green-yellow band is located on the right, and inversely for the transfer element with earth on the left. A switch
(or circuit interruption element) will always include a transfer element with the earth on the right and a transfer element with the
earth on the left. Add the references for special lengths using the length of the element, with the transfer element included.
Available in versions without earth conductor, line with black band. Add '- B' after the reference (e.g. ME2525-B ). Caution! The
