Cable YJV-VV-4 * 240 + 1 * 120 / 1KV What does it mean?

KvvRP-2x1.5ZC-KVVP-3x1.5vv-3x25 + 1x16ZR-KVVP-7X1.5ZR-KJVP-3X1.5vvP22-3X6 + 2X4ZR-YJV-4X6vv-3X70 + 1X35WZC-F46Y22-1-3X10 + 1X6ZR-YJV- 3X120 + 1X70KvvR-10X1.5ZR-RVVRP-2X1.5KVV-14X1.5ZR-YJV-4X2.5 A total of 14 specifications. I know what the specification means. But do not know the model description of the meaning. There are, for example, the above WZC-F46Y22- (1-3X10 + 1X6) this specification is also some do not understand. Want to understand the 14 examples of what the model specifications to write out what the meaning. Google had cable knowledge I have seen, but still some do not understand, thank you ...................... Question added: The above examples include the model and Specifications, in front of the model, followed by more specifications

Answer:

Before heat shrinkage can be inserted into the cable after the heat shrinkage can be greater than the thickness of the cable outside the coating and pay attention to the voltage level to choose the heat shrink tubing This is the focus you describe too abstract, so can not give a specific answer because heat shrink tubing points a lot model
In the GB-96 "thermal power plant and substation design fire safety regulations" Article 9
Casing is respectively heat shrink on each single cable, the larger diameter of the cable has a corresponding heat shrink tubing, you buy the direct write line specifications models, manufacturers will be based on your cable specifications model to provide you Heat shrink tubing, do not have to write the diameter of the heat shrink tubing!
