Selection of intrinsically safe cables
Thread Content
What are the specifications for intrinsically safe cables, and how to choose them?
Some information on the specifications and models of intrinsically safe cables; I hope it will be helpful to you.
If the insulation is black, it’s called a regular cable; if the insulation is blue, it’s called an intrinsically safe cable. Cable manufacturers don’t provide intrinsically safe cables, so what can be done? Replace the wire with one of copper, right~~~ So, if you have a cable with black insulation, just cover a section of it with blue heat-shrink tubing, or wrap it several times with blue tape – and it will then function as an intrinsically safe cable! That’s what my brother thinks: lol. . . Cables are nothing but intrinsically safe. . . In the years when my brother entered the industry, there was no such thing as an armored cable. . . The instrument has intrinsically safe explosion-proof certification, so there’s no issue with cables. . . . . . . .
For a bundle of cables, it is possible to measure its distributed capacitance and its distributed inductance. . . If something goes wrong, you simply calculate based on the values specified by the manufacturer; but do you really have the confidence to ensure that the total capacitance and inductance of the current circuit meet the intrinsically safe requirements? Bro thinks that measurement is what truly matters. . . Intrinsic safety cable? It’s complete nonsense. . . It’s for those silly kids. . {:3_51:}
Based on the cross-section you require, whether it’s multiple strands of flexible wire or a single core of rigid wire, whether shielding is needed, whether it’s a split-screen or single-screen design, whether armor is required, how many cores there are in one cable, and the color requirements for each branch cable
