Is it mandatory to use cable trays for indoor cable routing
Due to their exposure to the open air because of the cable trays, the wires contained within need a very durable outer covering. The regulations dictate that the cables must either be Type TC (also known as Tray Rated) or must be metal-armored (Type MC). This article explains the main requirements and good practices for cable tray systems, including tray types. The primary rulebook used in the safe use of cable trays is NEC Article 392. This is a description of how to select, install, and support these metal or plastic frames, on which electrical wires are installed. Grounding and bonding are mandatory for metallic trays. Tray fill limits must be calculated properly.

What does PD in electrical cable trays represent
In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. This is often due to imperfections in the cable's construction, such as poor workmanship, water treeing, manufacturing defects, or excessive bending. If you don't know you can't work with SLD drawings. You can be a. B manufactures its cable tray in a range of materials with a variety of finishes.
