Aerial insulation ABC cable Detailed Product Description Single core aerial cable(overhead cable) conductor: cooper or aluminium insulation:XLPE, PE, PVC Application Overhead insulated cable may be installed in the streets with dense trees close to the buildings, site of urban construction and lead to transformer. Using this cable, it is unnecessary to prune the branches, so that reduce the across and parallel distance of the cable. It is convenient to install and high mobility. It can reduce accidents of electric shock and power failure causing by circuit troubles. To guarantee supplying of electric power for industry, Single core aerial cable (overhead cable) could make sure residents safety. It is especially suitable for an old city, which has densely buildings, densely population and narrow streets. Our overhead insulated cables have formed a system, such as single core, two-core, three-core and four-core. There are conductors of aluminum, copper or aluminum conductors steel-reinforced.

Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
In the air defense regulations, the pipelines of the air defense zone need to be treated with the protective wing ring. The bridge frame is designed according to the cable laid in the bridge. The cable size and quantity determine the size and quantity of the casing. Increase the standby, air defense requirements casing with hot galvanized treatment, both sides of the exposed wall shall not be less than 100 mm, wing ring production can refer to rigid waterproof casing or flexible waterproof casing (explosion-proof). The general construction plans will have a clear sign, or should be presented to the Design Institute in the trial.
Q:The computer host is always start to stop, resulting in the last can not start. What is going on?
GB-2002 provides: metal cable bridge and its bracket and the introduction or extraction of metal cable ducts must be ground (PE) or zero (PEN) is reliable, and must meet the following requirements:
Q:Power cable inspection, how many meters should be sampled?
installation quota: cable ZR-YJV-4 * 70 + 1 * 35 is a five-core cable, you can refer to sets of "copper power cable laying cable (section mm2 below) 120? Cable "quota, and the fixed sub-sub-multiplied by the coefficient 1
Q:What are the requirements for the spacing between the strong and weak wires?
DIY notebook, I recommend you look at the Jingdong Mall, where there are genuine hardware and equipment, that is just the same as the same to buy back, you have to go home to assemble it! Such as CPU, graphics cards, hard drives, processors, heat sinks, monitors and the like can be bought
Q:Brief description of the difference between cable and cable.
Will not interfere with the middle there is no strong electricity! Cable no problem, may be the cable signal as before, you can use a waterproof tape wrapped up ah, do not exposed ah! If the wall with 220V power, then it is easy to string into the TV, the consequences ...
Q:Choose the configuration of good or bad computer graphics card memory processor, etc., how to choose a different manufacturers
Calculation method: the amount of engineering calculation formula: L = (pipe length calculation + wire reserved length) × with the number of cross-section wire. Note: plastic pipe should not be flattened, cracks, no debris in the tube, cut the mouth should be flat, the nozzle should be shaved plastic wire pipe connection using glue bonding, plastic pipe bonding must be tightly tight, and in the pipeline plug on the plastic pipe plug, to prevent the paddle, plug tube concrete floor, wall and brick structure of the various switches, socket bottom box , The lamp junction box and the pipe connection must be connected with the wiring, is strictly prohibited plastic pipe directly into the junction box dark in the concrete junction box requirements with wet cement paper or plastic foam filled with internal, not allowed to use The cement paper packs its outside. Embedded in the floor, the shear wall of the plastic pipe, the junction box should be fixed firmly to prevent the shift
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
The 4.0 square wire refers to the air conditioning power cord single copper core cross-sectional area of 4 square millimeters.
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: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:What is the difference between the control cable and the compensation cable?
. you want to achieve remote switch, right? In fact, from the host side of the original fixed switch button that cut the two lines, and then then you need to extend the extension cable you can, the super simple; . Internet cafes router, through the exchange (or hub) , Can achieve port expansion capabilities, you can access a lot of computers, but the Internet speed is limited by the router exit speed, that is the maximum speed will not exceed the router exit speed, and broadband providers will be on the server side of the uplink and downlink speed (That is, to provide customers with the speed) restrictions.
