How many control cables are there for 1 pump? How many cores are inside? What are their respective functions? Thank you for the advice
It depends on the schematic; are you asking about the cables that go to the site? Generally, one control cable is required; cable 2-61 is commonly used, with 5-core, 7-core, 10-core, 14-core, and 19-core versions available. The design should be based on the requirements of the secondary circuit. For large motors, such as those with a power rating of over 75 kW, traditional designs involve the use of ammeters on-site, which requires an additional current cable ； Cables going to the DCS are all shielded cables; layered shielding is acceptable, as is a combination of layered shielding and overall shielding. In principle, two cores per cable or per pair are used, while three cores are used for applications such as temperature control.
That’s not necessarily the case; it depends on the current circumstances.
Sir, may I ask what exactly are the 5-core, 7-core, 10-core, 14-core, 19-core types, as well as the 3-core temperature control type? Which wires do they refer to? ?
