11. The outermost strand of the power cable conductor is leftward.
12. In the VV3*70 cable structure, there are 3 insulated cores, and the conductor nominal cross-sectional area is 70mm2.
13. The difference between fire-resistant power cable and ordinary power cable is:
The fire-resistant power cable can continue to operate in a defined state when it is burned under a prescribed fire source and time. Ordinary power cables do not have this capability.
14. Flame-retardant cables can be classified into Class A, Class B, Class C according to their flame retardant ratings.
15. According to the number of insulated cable cores, it can be divided into 2 cores, 3 cores, 3+1 cores, etc. YJV-8.7/10KV3*120 is a 3-core cable.
16.YJV-0.6/1KV2*50 Decomposes this cable type. Cable type: YJV Voltage rating: 0.6/1KV Number of cable cores: 2 Conductors Nominal cross section: 50 mm2 17. The role of the shield of the KVVRP control cable is: : Shield the external magnetic field.
18. The pitch diameter ratio is the ratio of the pitch of the helix formed by a component of a cable to the outside diameter of the helix.
19. In the cable structure, the structure of the insulated wire core is generally round, fan-shaped, and tile-shaped.
20. ISO stands for International Organization for Standardization and IEC stands for International Electrotechnical Commission.
twenty one. According to different needs, the experiment of wire can be divided into type experiment, exemplary experiment and pressure test.
22. Bare wire refers to a wire without a cover.
23. Insulated cores of cables The main cores are generally represented by red, yellow-green, and three colors, while the neutral lines are represented by blue, black, or two-color.
24. The control cable voltage level is generally: 450/750V
The standard used for 25.1KV overhead conductors is: GB12527-90
26. Special cables are cables designed to meet certain specific occasions, such as high-temperature cables, and the common symbol F (F46) stands for the product name: polyfluorinated ethylene propylene 27. As people's environmental awareness is strengthened, The new environmental protection cable comes out, WDZN stands for: Smokeless low-halogen flame-retardant fire-resistant cable 28.YJV23-0.6/1KV, 2 stands for steel tape armored: 3 stands for: polyethylene outer sheath.
29. Wire and cable conductors are commonly used materials: copper and aluminum.
