Q:The living room to the bedroom cable does not work
Low voltage and wire aging has nothing to do with the cross-section of the wire, the cross-section is small, then the resistance of the wire is large, the pressure drop is large, the user's voltage will be reduced, but also with the wire and wire connection resistance, contact resistance Large, but also cause the user to drop the voltage, low voltage and the aging of the wire has an indirect relationship, the wire aging, that there is a certain history, and in recent years, rising living standards, household appliances also increased, with the time Increased, the power has increased, relative to the wire is concerned, is overwhelmed, so the line is often the place where the line voltage is very low
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:How to connect the power cable pre-branch connector
Pre-branch cable should be fully cooled before the plate can be installed, otherwise it will cause the connection flat, affecting the appearance of packaging should pay attention to branch and trunk The end of the seal, to prevent the core of the water
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
The size of the jumper varies with the specifications of the bridge, which is uncertain; the so-called repetitive ground is at least two that is the beginning and end of the end, if the length is enough, the need for intermediate isolation to do the appropriate length of the ground. Stressed that a certain attention to the ground is connected to the power grid on the ground, not directly into the ground.
Q:Power cable ZRYJV-4x70 + 1x35 What does it mean?
2 cable in a variety of environments in the laying of the layout, spacing should meet the design requirements
Q:The telephone line, TV line, cable, power lines are worn to a wire tube, what will happen?
This is the wiring of the cable wiring formulas: the next five is 10 square below the current per square 5A current wiring, one hundred and twenty is more than 100 square per square 2A, 25335 three circles, meaning 10 (Excluding) or more, 25 square feet per square 3A wiring, 35 square (inclusive) or more, 100 square (excluding) the following per square 4A line, that is, 25 square feet, 35 square feet per square by 3A or 4A wiring 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:Engineering materials inspection, all types of cable wires should be issued a test report?
That is to tell you the code, then you will not do now you have to do the password
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
3 + 2 and 4 + 1 are the number of cores of a cable, a cable inside is not a line, is insulated with each other 2 or . 3 +. 4 +1 line, 5 lines , Respectively, called 2 core or 3 core, 3 +2 core, 4 +1 core, 5 and other core. 3 + 2 cable 3 is the three phase lines, the diameter of the line as large, 2 is the zero line and the PE line, the diameter of the line as large; 4 + 1 cable 4 is the same as the three lines and the same diameter, 1 is the PE ground wire is a separate diameter; five core is the phase line, zero line and PE line are the same diameter, 2 core and 3 core is also the diameter of the line. In the end with a few cable, the design specifications are provided! A few words are not clear!
Q:The difference between power cable and overhead cable
Insulation structure is not the same, the number of core is not the same. Power cable generally 3-4 phase, overhead cable general core. Power lines can be divided into overhead lines and cable lines. Overhead lines with less investment, easy construction and maintenance, easy maintenance and repair advantages, the disadvantage is the natural conditions (wind, snow, ice, lightning, etc.) have a greater threat to operational safety. In order to save the country's construction funds, the general use of overhead lines is appropriate. However, when the conditions are subject to restrictions (such as overhead lines laid in difficult or special requirements), the use of cable lines. Cable and overhead lines compared to poor heat dissipation, it should be considered in the short-circuit conditions of thermal stability. Therefore, in addition to high-voltage cable cross-section in accordance with the economic current density, allowing voltage loss, long-term allowable current selection, but also according to short-circuit thermal stability conditions for verification.
