The quality of the wire tube is too bad! Depends on the degree of flat, if not affect the use of no relationship, such as the impact of threading or over the water will use the hammer to cut after the re-open.

Q:On the cable cross-sectional area, I would like to ask 3 * 10 +2 * 6 under the cable casing, casing to thick, the best formula

No problem, 1440 * . off point shadow effects no problem. Wow can only be used to 2 core, so if you can, try oc

Q:Cable YJV-3 * 70 + 2 * 35 general wear large SC tube? Ask you.

Cable (cable transfer box) into the end refers to: outdoor cable into the room, the cable jacket to peel a certain length, so that the fiber casing and reinforced core exposed, the following operations: 1. The metal core and ODF frame . the fiber casing with a plastic tape in the ODF frame lashing neatly, each casing corresponds to a melt disk; 3. will be a set of fiber sets And then the pigtail and fiber in the melt tray disk neatly; 4. The cable tag fixed on the cable above the optical cable to identify; 5. The fiber will be the core of the fiber The corresponding open route is filled with the data label on the ODF shelf to maintain the search.

Q:Home improvement is the PVC pipe is a good pipe or galvanized steel pipe? why?

Control, generally can be connected to three two-core control loop or two three-core control loop, there is a spare. Control cable from 2 to 10 core has, depending on the need, usually from the same control unit out of the control line are as much as possible in a cable, easy to maintain. Orthogonal twisted conductor core or cable insulated wire core, stranded structure are starting from the center of a lower layer, each additional layer, an increase of 6 core, that is, 1 +6 +12 +18 +24 +30 Each of which is adjacent to each other and has a difference of 6 cores. Practice has proved that in the outer layer of each layer plus 6 core after the total number of cores can be formed around the outer circle of the outer layer of each core connected to the outer circle, this can be used to explain the principle of geometry.
