Q:What is the heat of the cross-linked cable?
Video cable refers to the transmission of video signals (VIDEO) cable, can be used as a monitoring system for signal transmission
Q:The computer host is always start to stop, resulting in the last can not start. What is going on?
Do not worry, no problem, the power cord can withstand the general high temperature, not recommended to use extension cord, the more joints more easily lead to some inexplicable problems.
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:Power Cable Check Well b-type covers show what?
Indicating the carrying capacity of the covers, according to "People's Republic of China town construction industry standards" to understand that: steel fiber reinforced concrete inspection covers are divided into A, B, C, D four
Q:What is the wiring principle in the home improvement circuit?
Section 4 "Downhole Cable" Article 466 No cable should be laid in the total return airway and the dedicated return airway
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Sub-strong electric power cable control cable transmission cable and so on
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
Is the size of the power cord size, that is, the thickness of the power line diameter, 4 square power cord diameter is 2.2 mm thick, the safety current between about 25-32A, that is, can withstand electrical power at 5500 watts or .000 watts Depends on the laying of the power cord, that is, the laying of dark lines or laying the line, the size of the safe current is not the same. Generally more than 2 air-conditioning use 2.5 square copper wire, 2 or more air conditioning should use 4 square copper wire.
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:Calculation method of wire and cable outer diameter
Usually check the table, in the cable samples or manual check.
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.
