FIELD: electrical engineering.
SUBSTANCE: proposed insulating duct has on one end suspension means made for its attachment to bracket used for installing instrument on tray socle; on other end it has casing designed to close bracket-mounted instrument in a spaced relation; this casing has side wall. Novelty is that suspension means are, essentially, canopies provided with fastening means minimum at two different elevations and at least on part of casing perimeter, at least upper section of casing side wall being removable part.
EFFECT: improved design of duct for trays of different type varieties without limiting its useful volume.
