Discussing the Selection Methods for Cable Trays

When selecting cable ladder types and varieties, if there is a requirement to shield against electrical interference for cable networks or to protect against external influences (such as corrosive liquids, flammable dust, etc.), it is recommended to use (FB) type槽式 composite corrosion-resistant shielded cable ladder (with cover).

In environments with high corrosivity, it is advisable to use Class (F) composite epoxy resin flame-retardant cable bridge supports. The supports and brackets should also be made of the same material to enhance the service life of the bridge supports and accessories. In areas prone to dust accumulation or other concealed environments, as well as outdoor locations, it is recommended to cover the bridge supports with a cover plate.

In addition to the aforementioned situations, tray-style, trough-style, ladder-style, glass flame-retardant cable bridge supports, or steel ordinary type bridge supports can be selected based on on-site environment and technical requirements. In environments prone to dust accumulation or other concealed locations, as well as outdoor settings, it is advisable to cover the bridge supports.
