Q:PVC pipe on the GV.215-16 (C) What does it mean
TC line laying is the use of wire steel pipe laying. Wire steel pipe is a thin-walled tube, the nominal diameter is the outer diameter of the pipe. SC line laying is the use of ordinary welded steel pipe laying. Ordinary welded steel pipe is thick-walled tube, nominal diameter is tube diameter.
Q:The difference between the instrument cable and the low voltage power cable
Surface brush fireproof paint is the fire-resistant bridge by fire time sub-level two three times as if 30 minutes 45 minutes and 60 minutes fire bridge should be lined with inorganic fire board, but this is very high in the general very little useful
Q:How high voltage armored power cable is grounded
Copper braided wire for cable and shielding lead wire. Stripped of the core of the copper shield with the outer layer of the plastic belt, the shield copper belt polished smooth, with electric iron, solder braided copper braid were welded in the three core copper shield tape. And then use the emery cloth polished armored steel strip welding area, with a soft copper wire and copper shield belt tied with three armored steel, and then use electric iron, solder braided copper braided with armored steel belt. In the sealed ground to fill the braided wire with solder to form a moisture-proof section.
Q:What recycled rubber is suitable for the production of wire and cable?
The power industry mainly includes electricity industry and power plants and other power cables industry is the power industry to do the cable and cable should belong to the power industry but does not belong to the system within the power system only includes the State Grid China Southern Power Grid five nuclear power plants and other large state-owned enterprises
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
3 + 2 and 4 + 1 are the number of cores of a cable, a cable inside is not a line, is insulated with each other 2 or . 3 +. 4 +1 line, 5 lines , Respectively, called 2 core or 3 core, 3 +2 core, 4 +1 core, 5 and other core. 3 + 2 cable 3 is the three phase lines, the diameter of the line as large, 2 is the zero line and the PE line, the diameter of the line as large; 4 + 1 cable 4 is the same as the three lines and the same diameter, 1 is the PE ground wire is a separate diameter; five core is the phase line, zero line and PE line are the same diameter, 2 core and 3 core is also the diameter of the line. In the end with a few cable, the design specifications are provided! A few words are not clear!
Q:Wire and cable manufacturing process (to be detailed)?
Copper core per square of the safe current (continuous use) for the 2.5A, intermittent use of 4A, according to the power count 550W-880W.
Q:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
You can shop on the ground floor of a layer of waterproof carpet (that is, the rural common 'kang seats'), the wire shop in the following, at the desk to stay a outlet hole, and the jack or electrical connection. Carpet can be bought in the hardware building materials store, as the traces of tape, you can go to the big supermarket to buy a special scrub, ask the salesman on the line. Wish you the best at work
Q:Emergency cable T-box and cable distribution box of the information?
The incoming and outgoing wires are electrically connected together The potential is the same, which is suitable for tapping or branch wiring It is common practice to add the number of lines back to the number of times The three-branch cable splitter box, which has three equipotential bonding points on each phase, can be used as a second or two-in-one Cable distribution box contains U, V, W three-phase, three-phase circuit structure is the same, along the row together 2 High-level distribution box High-level distribution box containing switching equipment, both from the ordinary distribution box of the tap, branch, but also from the power supply circuit control, conversion and change the mode of operation The switch fence roughly divides the cable circuit into the inlet and outlet sides, and the potential on both sides can be different The switchgear itself has a larger volume, so the high-level distribution box size is relatively large, the height is generally 14 ~ 18m, the depth of about 09 ~ 10m, the length of the number of switching devices according to the number, M to 24 m The shape of the box is similar to that of an outdoor box transformer, and there are a number of active doors on the shell Some doors are designed for the operation of the switchgear Some doors are provided for the installation or maintenance of the cable connection device The
Q:How long is the service life of the cable?
For corrosive environments, cable trays with suitable corrosion resistant coatings should be used
Q:What is the use of wire and cable per square meter of residential building?
You can use sc. if too long, or bend the best use of the bridge
