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:Whether high voltage cables can be built in belt corridors
First of all, it should be noted that the short circuit is caused by the current is too large, short circuit occurs when the short-circuit current will be very large, can not be used to describe how many times, and electrical design to consider the wire cross-sectional area will not be great, Heat, so the conductor will be hot
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:The difference between power cable and overhead cable
. the power cable occupies less. Generally buried in the soil or laying in the room, the channel, the tunnel, the line between the insulation distance is small, no tower, covers an area, basically does not occupy the ground space. The overhead cable is the opposite. . power cable reliability. Affected by climatic conditions and the surrounding environment, transmission performance is stable, high reliability. . the power cable has to ultra-high pressure, large capacity development of more favorable conditions, such as low temperature, superconducting power cables. . the power cable distribution capacitor larger. Overhead cable is the opposite . the power cable maintenance work less overhead cable is the opposite . the power cable electric shock is unlikely. The overhead cable is the opposite
Q:What does the cable ZR-YJV22-4 * 16 mean?
ZR-YJV1KV6mm ^ 2 * 3 for the copper core flame retardant XLPE insulated PVC sheathed power cable, three core, nominal cross-section 6 square millimeters, rated voltage 1kV, model specifications specification: ZR-YJV1KV3X6mm ^ 2.
Q:The difference between the instrument cable and the low voltage power cable
Silicone rubber insulated power cable blistering, stomata is caused by the process problems, silicone rubber insulated cable in the injection should be used when the vacuum casting, raw materials to fully degassed, otherwise there will be blistering and stomata, some small factories because there is no vacuum Injection equipment, coupled with poor degassing process will produce this poor product, to solve this problem is the first workshop to maintain constant temperature and humidity, the purchase of excellent performance of the vacuum injection equipment and vacuum mixing equipment, strict control of process parameters. Silicone rubber power cable for AC rated voltage 0.6 / 1KV and below fixed power transmission line or mobile electrical connection cable, the product has heat radiation, cold, acid and corrosive gases, waterproof and other characteristics, the cable structure is soft, Radiation, high temperature (alpine) environment, electrical performance and stability, anti-aging performance, long life, widely used in metallurgy, power, petrochemical, electronics, automobile manufacturing and other industries
Q:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.
Q:Lighting wire, I do not know is it. The When to use BV1 * 2.5, when to use 2 * 2.5, when to use 3 * 2.5, when to use 4 * 2.5,
It does not look good, but also affect the wallpaper, wallpaper, in full swing, and then from the chain reaction, then it is worthless, it is recommended to use decorative decorations decorated, perhaps alone for more suitable wallpaper pattern or color ... that does not affect the wallpaper Can also play a decorative effect ... Thank you
Q:What kind of material should be selected for the fixing bracket of the cable trunking
General 2.5 square wire load is 2 kilowatts, and rubber sheathed cable, full load can reach 3 kilowatts are no problem (estimated again, it is not safe). The load level of the wire is mainly dependent on the current, but also on the voltage level. Under normal circumstances 50A below 1 square millimeter safe carrying capacity is 6A, 50 ~ 100A current 1 square millimeter of the safe carrying capacity is 5A, 100A current above the general take 1 square millimeter of the safe current is 2.5A; so many large square copper cable You can calculate the current. According to the three-phase alternating current formula: P = 1.732 * U * I * cosφ, cosφ is the power factor, select 0.8; this is the three-phase power calculation formula. Single phase: P = U * I * cosφ, cosφ is the power factor The power factor is 1 for the resistive load and 0.8 for the inductive load.
Q:Wire and cable manufacturing process (to be detailed)?
Hello, copper wire per square safe current-carrying 6A, .05X6A = 3A.X220V = 660W, 3AX380V = 1140W, aluminum core for the same 4A algorithm,
