Q:How to identify the quality of the lock of the hotel lock?
Ming assembly line tube card 1 meter a, turn from the wall 10 a square, far away, the tube will fall down.
Q:How to effectively reduce the cost of car wiring harness?
5mm, that is 100: 76 followed by the proportion of push The height of the isosceles triangle at the time of the bend of the 200 high bridge is also suitable for the adjustment of the 90 ° bend; the use of the tool is cut off and the bending of the bridge is 90 ° Bridge elbow As for the length of the bridge to limit the restructuring of the elbow, as long as the use of junior high school learned by the simple mathematical knowledge of the calculation, any length distance can be controlled The use of mathematical methods simple calculation, a variety of angles, the length of the elbow can be made zuo
Q:Copper core power cable models which several kinds
They have two kinds of total use, one is the transmission current, one is the transmission signal
Q:What is the radiation of the laser scanning scanner?
Semi-conductive shield The semi-conductive shield is usually disposed on the outer surface of the conductive core and the outer surface of the insulating layer, referred to as the inner semiconducting shield and the outer semiconducting shield, respectively The semiconducting shield is made of a semi-conductive material with a low resistivity and a low thickness Internal semiconducting shielding layer is to uniform the outer surface of the electric field, to avoid the conductor surface is not smooth and the core stranded by the air gap caused by the conductor and insulation occurred partial discharge The outer semiconducting shield is in good contact with the outer surface of the insulating layer and is electrically connected with the metal sheath to avoid partial discharge of the metal sheath due to defects such as cable insulation surface cracks For non-metallic jacket in the low-voltage power cable, in addition to the semi-conductive shielding layer, but also to increase the metal shield Metal shield is usually made of copper or copper wire wrapped around the main play the role of shielding the electric field
Q:Brief description of the difference between cable and cable.
Optical fiber (optical fiber) is designed to meet the optical, mechanical or environmental performance specifications, it is used in the jacketed jacket in one or more optical fiber as a transmission medium and can be used alone or in groups of communication cable Component. Fiber optic cable is mainly composed of optical fiber (such as the hair of the glass) and plastic protective casing and plastic skin, the cable without gold, silver, copper and aluminum and other metals, generally no recovery value. Fiber optic cable is a certain number of optical fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer cover, used to achieve optical signal transmission of a communication line. That is, a fiber formed by a certain process by an optical fiber (optical transmission carrier). The basic structure of the cable is generally composed of cable core, reinforced steel wire, filler and jacket and other parts, and also need to have waterproof layer, buffer layer, insulated metal wire and other components. A cable is usually a rope of similar rope made of several or several sets of wires (at least two in each group), each of which is insulated from each other and often twisted around a center with a height Insulated cover. Cable with internal power, external insulation characteristics. Category cables are power cables, control cables, compensating cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum cables and so on. They are composed of single or multi-strand wire and insulation layer, used to connect the circuit, electrical appliances and so on.
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:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
Color line, HDMI cable, S-terminal line of the three transmission video signal (HDMI can also transmit audio signal); coaxial line is the transmission of audio signals
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)?
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:3 (WDZBN-YJV-4x240 + 1x120) cable how to interpret
3 halogen-free low-burn A-class flame-retardant cross-linked insulated PVC sheathed 4 main core per core 24 square millimeters, 1 ground 120 square millimeters cable.
