Under different construction conditions, which cable tray is used is also different. Next, Jinan Cable Tray will introduce the selection of cable tray under different construction conditions and the maintenance of this product.
Selection of cable tray under different construction conditions
In the environment of corrosive liquid, flammable dust, etc., or in the cable network that needs to shield electrical interference, or when installing cable bridges outside the protection, the FB type covered trough composite anti-corrosion shield bridge shall be selected.
Class F composite epoxy resin anti-corrosion and flame retardant cable tray shall be used in highly corrosive environment, and its corbel and support shall also be made of the same materials to improve the service life of the tray and accessories. Cover plate can be added in the environment where dust is easy to accumulate and other places that need to be covered or outdoor places.
In the public passage or outdoor crossing road section, the bottom of the bottom rung can be added with a pad or used with a pallet. When the large span crosses the public channel, the bearing capacity of the bridge can be improved according to customer requirements.
According to the needs of the construction site, tray type, trough type, ladder type, glass anti-corrosion flame retardant cable tray or steel ordinary cable tray shall be selected.
Maintenance of cable tray under different construction conditions
Open the cable reel regularly to see whether its internal and external structures are guaranteed. In fact, due to various external factors, the cable tray may become loose and deformed from time to time, which may hinder the work of the wire. At present, auctions can be found as early as possible by checking the old rules, so as to prevent problems in the variable power transmission link and take into account the dangers of people and materials around.
It is precisely because of the climate and other factors that the operating environment of the cable tray, as well as the components at the connection and fixing points, are open. The components of the cable tray are afraid of damage and corrosion, so we should realize this.
Make the dust or other sundries outside the cable tray bright, make the cable tray hard, bright and fresh, and make the surrounding environment of the covered cable tray clear enough to prevent the tray from corrosion, so as to better ensure the appearance of the tray is intact.
