Q:What is the installation specification for the cable tray bracket?
WDZ low smoke zero halogen flame retardant power cable. WDZN low smoke zero halogen flame retardant power transmission cable. W-halogen-free, D-low smoke, Z-flame retardant, N-refractory, YJ-XLPE insulated, V-PVC sheathed YJV-XLPE insulated PVC sheathed power cable. Model of the principle of omission: wire and cable products, copper is the main use of the conductor material, so the copper code T write, but bare wire and bare conductor products except. Bare wires and bare conductor products, power cables, electromagnetic wire products do not indicate a large class code, electrical equipment, wire and cable and communication cable category is not listed, but set out small class or series code. Item 7 is a special use of special occasions or additional special requirements of the mark, in the "-" after the alphabet letters. Sometimes in order to highlight the item, write this to the front. Such as ZR- (flame retardant), NH- (refractory), WDZ- (low smoke and halogen, enterprise standard), TH- (for hot and humid areas), FY- (anti-termite, enterprise standard).
Q:Is the power cable considered a fixed asset?
According to the total number of meters, such as where to where a total of how many kilometers (meters). Power system fixed assets asset management software - TU Teng fixed asset management software.
Q:The difference between power cable and overhead cable
His answer is correct! There is overhead cable generally use aluminum core conductor! Because light weight Overhead cable under normal circumstances are 6kV below the cable! If the voltage level is high, you need to do special craft production!
Q:How to determine whether the square of the cable is standard
Horizontal laying of the cable within the cable, generally do not need fixed, natural laying can be. Vertical laying section of the cable within the bridge, with the need to match the line card, the use of tied rope (multi-purpose single insulated wire) one by one fixed cable, fixed spacing should meet the requirements. According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
Q:What does ZR-YJV 6mm2 * 3 cable mean?
The initial also said that car 3S brand stores, mainly refers to the front of the three S
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
100-200 door is to call the wiring module, testing and convenient. The The Switch on the use of national prestige WS824 figures. The
Q:Where the computer can be a bare chassis. Which hardware inside the framework
The general process is: program-controlled switches generated by the phone number will generally pass through a card board, and then board through the copper cable to the horizontal module, the horizontal module through the jumper connected to the straight line module; Copper connected to the general distribution frame, which also contains 110 patch panels! This 110 patch panel is very old. Now generally do not have a!
Q:W22 in the cable on behalf of what
Not W, is VVVV22 means the meaning of plastic insulated plastic sheath with armored copper cable. Wire and cable: wire and cable is the transmission of electrical energy, electrical signals and electromagnetic energy conversion to the wire products. Cables are usually made up of cable cores that transmit electrical or electrical signals and protective, insulated sheaths. A cable with only one cable core and a smaller diameter is often referred to as a wire. Also some wires do not have insulated sheaths, called bare wires. The cable in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost).
Q:Wire yellow and green, respectively, that line of fire or zero line
Insulated piercing clamp is mainly composed of reinforced shell, puncture blade, gasket, waterproof grease, high strength bolts, torque nut and cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal Cap sets, to determine the main line branch position, with a socket wrench screw clamp on the torque nut, the process of contact with the blade will pierce the cable insulation, contact with the conductor, the sealing ring ring around the cable puncture position, the shell Grease overflow, when the torque reaches the set value, the nut torque mechanism off, the main line and branch line is connected, and waterproof performance and electrical effects to meet the standard requirements of the parameters. T-shaped terminal is composed of insulation base, wiring frame, fire shield composed of three parts, wiring box by the wire clip, screws, nuts and variable frame and other components, wiring clip and wire contact surface was wrapped in the shape of the dentoid staggered structure, With a large area of ​​spinous process, pressure line reliable features. Through the different shapes of the wire combination of each other, can form a double connection, the lower access to the main line, the upper access to the branch line, the formation of continuous "T" -shaped connection, the product is a protective cover, especially suitable for cable trays and cable And other small places to use, can effectively prevent the suffering of the mouse on the line.
Q:How to identify the quality of the lock of the hotel lock?
If you are using a cable that is suitable for direct burial, you do not need a casing. But in the place into the building, should be casing, in order to protect. General steel pipe can be.
