OUTDOOR INSULATED HANDHOLE SERVING FOR THE PASSAGE OF CABLES

摘要

Novelty: an outdoor insulated handhole serving for the passage of cables is disclosed. Constitution: two uniformly-constructed units (monoblock construction), the internal and the external one: the internal unit has the form of a cube or another shape and is made of polyvinyl, cast iron, steel or stainless steel; the external unit has no floor and its sides are perforated to allow the removal of possible waters so that the internal unit hosting the cables and closing at the top with a flat cap extending from its main body can be protected. The cone-like floor ends in a hole blocked with a similarly-threaded conical plug bearing a recess enabling the easy removal of the conical floor and the prompt emptying of water in case of washing. The absence of elastic packings or metal screws between the main body and the caps reduces the total cost of the invented handhole.
