What model is the corrosion-resistant cable tray NB/T42037?

NB/T42037 is a standard for anti-corrosion cable trays, which specifies the models, requirements, inspection rules, markings, packaging, transportation, and storage of metal cable trays used for power system installation. This standard applies to cable trays used indoors and outdoors, as well as to cable trays used in newly constructed and renovated industrial and civil buildings, public facilities, transportation facilities, and other places. The models of this standard include trough type cable trays, tray type cable trays, step type cable trays, and other types to meet the needs of different locations and cable types.

The design of anti-corrosion cable trays should consider factors such as the number, diameter, bending radius, and weight of cables, and should also have good anti-corrosion performance to adapt to different environments and corrosive media. According to the standard requirements, manufacturers of anti-corrosion cable trays should purchase, process, inspect, and test raw materials in accordance with the standard requirements to ensure that the quality and safety performance of the products meet the requirements. At the same time, the bridge should be regularly inspected and maintained during use to ensure its normal operation and safety. In addition to the above standard requirements, anti-corrosion cable trays also need to comply with relevant electrical safety regulations, such as having grounding protection devices, good electrical insulation performance, etc. In addition, environmental protection requirements should also be considered, such as environmental protection measures during the production process and product recyclability. In short, choosing anti-corrosion cable trays that meet the standards can ensure their safety and reliability, extend their service life, and reduce maintenance costs. At the same time, it also meets the requirements of environmental protection and sustainable development.
