Precautions for purchasing stainless steel cable tray Posted by : admin / Posted on : Aug 27， 2021

1. When the natural environment of the daily task is affected by sunlight, oil, adhesive liquid, flammable smoke, etc., or requires shielding of cables and wires that interfere with signals and other natural environment regulations, stainless steel cables with perforated metal trays should be used Bridge.

2. Stainless steel cable trays can be used in the area with fire safety regulations. The cable tray supports and trays can be equipped with fire-resistant or flame-retardant panels, nets and other materials to form a closed or semi-closed structure. The surface of cable trays and seismic supports are painted with fireproof and safety coatings and other countermeasures. The fire protection function of all personnel shall meet the requirements of relevant regulations or limits. In sites with high fire safety regulations for engineering projects, it is not suitable to use aluminum alloy profiles and stainless steel cable trays.

3. In the design of construction projects, the layout of stainless steel cable trays should be comprehensively compared based on economic development book value, technical feasibility analysis, operational safety factors and other factors to clarify the ** plan. It also needs to fully meet the requirements of engineering construction equipment, Regulations for maintenance testing and cable laying.

4. In places where smoke and dust are stored at will, the stainless steel cable tray should use the rear cover; in the public safe passage or outdoor over the distance

5. The height-to-width ratio of the stainless steel cable tray when laying horizontally above the sky is generally not less than 2.5m. When laying vertically, the unit below 1.8m above the sky should be covered with metal materials for maintenance, but laying in public houses of electrical equipment Beyond time. The stainless steel cable tray is laid horizontally on the machine equipment compartment or the upper troll road and is less than 2.5m, and the maintenance grounding device should be used as a countermeasure.

6. Stainless steel cable roller, wire troughs and seismic supports are used in adhesive natural environments. They should be made of corrosion-resistant rigid materials, or corrosion-resistant treatments. The corrosion-resistant treatment methods should meet the requirements of the natural environment and durability of the project. Regulation. For sites with high anti-corrosion function requirements or clean and tidy locations, aluminum alloy profiles and stainless steel cable trays should be used.
