Xiaobai Cai: How to create this ingredient list?

Order whatever is needed for the construction. Construction methods and material specifications vary slightly from one factory to another.

KVVP copper core PVC insulated and sheathed stranded shielded control cable, 4*1.5, length 3.5 meters; U-PVC flame-retardant cold-bend electrical conduit with a diameter of 16 mm, also 3.5 meters in length; two 90° elbows are included as accessories (some clients require iron pipes); wiring terminals? Electricians should all have them

Thank you. What other accessories are needed? Things like union fittings, for example

Is the transmitter intrinsically safe or flameproof? If it is intrinsically safe, purchase this model of cable, ZR-ia-KVVRP; for explosion-proof use, choose ZR-KVVRP. The number of cores should correspond to the number of signal terminals. . There is an extra core as a spare. As for the specific connections, our company follows this standard process: instrument – bellows – welded steel pipe – (bellows) – cable tray – bellows – enclosure. So, as long as the threads can be screwed together, that’s sufficient

1 computer shielding cable of type ZR-ia-DJFPVP, 1*2*1.5; galvanized angle steel of size ∠50*50*5 meters; galvanized welded steel pipe with a diameter of DN20 meters; 2 G3/4" wire threading boxes; 1 flexible tube with a G3/4-M20*1.5 (rubber/304) sealed connection, or 1 gland. The material for the wire glands and the flexible tubes used for cables should be determined based on the explosion protection requirements at your site. For ordinary anti-corrosion and dust-proof cast aluminum wire glands, rubber flexible tubes will suffice. Since it’s a temperature transmitter as you mentioned, I think a 2*1.5 cable will work fine; of course, using a KVVP cable is also an option. Angle steel is used to make supports for protective pipes; since the temperature transmitter is located at a height of 1.4 meters above the ground, if there is no structure available for support nearby, the construction team must install a small pillar from the ground level to hold the protective pipe in place. If there are process pipes or steel platforms available, then less angle steel is needed. It depends on the type of connection required at the site control cabinet – if the box comes with internal threaded connections, flexible hoses can be used; otherwise, flanged connections are necessary. In cases where explosion protection is required, armored, explosion-proof sealed flanges should be used. Installation materials such as expansion bolts are considered auxiliary items and are generally purchased by the construction party itself. Above

Here’s some experience for you: be sure to apply for more quotes. Quotations are usually given based on a percentage increase of 20% to 30%, so there’s no need to worry about any interference factors. First, use a 220V power supply for the control box, and for the temperature sensing cables, it’s better to use 2-core cables with shielding. The brackets can be connected directly to the control box; the supplier will definitely help you set it up properly. Just buy the temperature sensors and that’s it

Thank you very much. Is it only the threaded connections that require flexible hoses, while internal threads don’t need them? There are three threaded connections under the control cabinet – are there any other components needed?

If there are flange connections, flexible pipes are not necessary; in explosion-proof environments with high safety requirements, armored explosion-proof flanges should be used. The cables should be equipped with armored covers to protect them from mechanical damage (although this is not strictly necessary). It is up to the construction party to purchase plastic or rubber cable guards for the ends of the protective tubes. If there are three flange connections, consideration should also be given to the way cables enter the box – select appropriate tubes and support materials accordingly. As for the supports under the box, I assume it already comes with supports; if not, determine whether it will be mounted on the wall or on some kind of support, and decide whether to use channel steel or angle steel as supports (similar to those used for insulation boxes)
