Cable lead length
Thread Content
Our company is involved in instrument installation; for the connections of instrument cables, flight wire connectors are generally used (explosion-proof flexible conduit is employed, but if not handled properly, water can easily get into the instruments). Are there any **standard specifications that specify the length of such flight wires? Thank you!
Dig~~~ **Standard regulations – if they even regulate how long your wire should be, then they’ll also regulate how far you can pee. If you have too much urine flow, they’ll cut you up; if you pee in the women’s restroom, you’ll be convicted of a crime and sent to labor camp :P**
It uses explosion-proof glands; what I’m asking about is the length of cable to be left unused.
What is a flying lead connector? Common name or scientific name?
If running wires is unavoidable, a U-shaped bend needs to be formed downward at the entrance.
What is a flying wire? Is it that we’re not professional?
The flying wire is the cable that runs between the conduit and the instrument; the part of this cable that is not enclosed in a flexible tube and is exposed outside is what we call a flying wire. The cable is sealed at the connection point used for the instrument, preventing water from entering the instrument and meeting the explosion-proof requirements.
This cable length specification does not specify a length. Just make sure it is waterproof and explosion-proof. Also, what you commonly call a flying wire might not be the appropriate term. The definition of a flying wire isn’t like that, haha. You can search on Baidu for the meaning of flying wire.
As you said, using flying wires is not allowed; not even one millimeter. You mean that as long as it meets the explosion-proof requirements, it’s good enough? The safety supervision department said it doesn’t meet the standards. Fix it quickly. It’s even possible to force you to stop production.
