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: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:Cable zc_y v22 what does it mean
No problem with the copper, the home is no problem as if you take a twisted pair as a telephone line KVV with BV material, the process is not much difference in the production...
Q:Why does the sparrow stand on the wire without electric shock?
12 meters below the road should be used to protect the tube, the use of rigid PVC pipe protection of course, but not necessarily have to wear armored cable
Q:20 tons of double beam traffic acceptance standards and content which
Change the data line ah, often with non-original battery will be filled with bad
Q:What does the cable ZR-YJV22-4 * 16 mean?
Copper core XLPE insulated PVC sheathed flame retardant power cable, three core, nominal cross section 6 square millimeters, rated voltage 0.6 / 1kV, model specification specification: ZR-YJV0.6 / 1KV3X6mm ^ 2.
Q:What is the cable for the YJV33 cable?
If there is a mutation in the target fragment, all the dideoxy-terminated fragments that are larger than a certain size corresponding to the mutant position have no wild-type system, and the rate of detection of mutations is improved for each occurrence of multiple changes in the mobility The ddF method overcomes the difficulty of SSCP analysis due to the effect of DNA length on SSCP, and produces a specific single stranded DNA by a dideoxycyclic acid to show that the DNA fragments with suitable length indicate SSCP changes
Q:Wire and cable manufacturing process (to be detailed)?
Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
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.
Q:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
. 1.8.7 / 10kV U value of 10KV, which can withstand the maximum voltage of 12KV8.7 / 15kV U value of 15KV, which can withstand the maximum voltage of 17.5KV2.8.7 / 10kV is 10KV system in the first Class II cable (fault time can be greater than 1 minute) 8.7 / 15kV is the first type of cable in the 15KV system (failure time is not more than 1 minute) 3.U0 / UU0 - conductor and insulation shield between the voltage U - the The voltage between the conductors is two, the cable is usually a few or several groups of wires [at least two] stranded from the rope similar to the cable, each group of wires insulated from each other, and often around a central twist The entire outer package has a highly insulated cover. Multiple in the air or in the ground, underwater, for telecommunications or power transmission.
