Cable tray application

Which products are widely used in petrochemical, metallurgy, electric power, the school of communication, high-rise building, etc

The selection of cable tray and recommendations:

1. Can independently set up within the building bridge, can also be attached at the various buildings and on the pipe gallery

2. The installation outside the building, if it is in near the sea or belong to the corrosion area, which must have the anti-corrosion material, moisture resistance, good adhesion, impact resistance properties of high strength characteristics.

Q: MR-150 * 75 What does it mean? Is the bridge of the electrical?: Electric fire mainly includes the following four aspects: First, the leakage of electricity The so-called leakage, that is, a line of a place for some reason (natural or man-made reasons, such as wind and rain, wet, high temperature, , Corrosion, etc

Q: Cable tray specifications are generally how to choose: Cable bridge selection design . to determine the environmental conditions Environmental conditions are generally three: corrosive environment, the normal environment, special environment. . according to the majority of cable, in the room can be along the column, beam, floor walk, as far as possible in the process along the pipeline to go. . calculate the load calculation in the cable bridge to the cross section of the unit length of the cable weight q and the total load GG total = n1q1 + n2q2 ... ... nnqn where: q1 q2 q3 ... ... qn for each cable unit weight (kg / M) n1 · n2 · n3 ... nn is the same number of cables G total <G (the allowable load of the cable to the reference load curve chart) . select the bridge according to the cable load and bridge installation of the environment to the bridge Load curve as the basis, to determine the type of bridge and specifications and column spacing, the length of the arm, the bridge level, the length of the column and so on. . according to the cable to the installation and installation of the environment to determine the fixed way of the bridge; hanging, vertical, (these two forms can be used unilateral fixed or bilateral fixed), wall side and so on. . a variety of cables in the cable bridge on the level of arrangement and inter-layer distance. Cable bridge level arrangement is: weak control cable in the top, then the general control cable, low-voltage power cables, high-voltage power cables in order: the following table: This arrangement is conducive to shielding interference ventilation, heat and so on.

Q: When the electrical installation of the cable bridge when the copper grounding wire: The simplest way is 20 to 30% larger than the outside diameter of the conduit / copper nose

Q: Bridge of the jumper no less than the number of square meters, and repeat the ground not less than the number of points: Electric lighting works like this, the power into the line to the main switch (which includes the meter). This section of the line requires a separate trunking, and then by the total switch branch several switch circuit, which several inside the loop; lighting circuit room 1 loop is a trunking. The room 2 loop is a trunking, the room 3 loop is a trunking, etc., the socket circuit . . they can share the same trunking wiring. for reference only.

Q: What is the meaning of the separation within the cable tray?: Wire generally refers to the outdoor overhead lines, there are high pressure, high pressure, low pressure of the points, but also by insulation, or conductor material points, of course, the second part of the indoor line, such as BV line, there are general The rod will be used on the ground BV line, as well as the ignition point on the high pressure cited off the line, high-voltage jumpers and so on this part of the wire, the general outdoor overhead line on the set of overhead line fixed, by cross-sectional area, Part of the line with the general sleeve cabinet wiring or BV line laying power cable with high and low voltage and control, signal, etc

Q: Electrical engineering bridge; two sets of cable bridge in the same height parallel laying, during which the net distance should be at least the number of centimeters. Thank you hurry: Please refer to GB electrical installation installation cable construction and acceptance specifications 5.3 cable duct laying 5.3.1 in the following locations, the cable should have a certain mechanical strength of the protective tube or the installation of protective cover: 1 cable into the buildings, tunnels, Through the floor and the walls. 2 from the channel lead to the poles, equipment, wall surface or house pedestrians easy to close, from the ground height of 2m below a section. 3 may have a gear that has been above the cable section; 4 other places that may be subject to mechanical damage. 5.3.2 There should be no water inside the pipeline and no clogging. When wearing the cable, do not damage the protective layer, can be used non-corrosive lubricant (powder). 5.3.3 cable laying in the laying of cables, should be clear, remove debris. 5.3.4 The number of cables in the pipe should meet the design requirements; AC single-core cable shall not penetrate the steel pipe alone. 5.3 Laying of cables in cable ducts 5.3.1 In the following locations, the cable shall have a protective tube of mechanical strength or a protective cover: 1 cable into the building, tunnel, through the floor and the wall. 2 from the channel lead to the poles, equipment, wall surface or house pedestrians easy to close, from the ground height of 2m below a section. 3 may have a gear that has been above the cable section; 4 other places that may be subject to mechanical damage. 5.3.2 There should be no water inside the pipeline and no clogging. When wearing the cable, do not damage the protective layer, can be used non-corrosive lubricant (powder). 5.3.3 cable laying in the laying of cables, should be clear, remove debris. 5.3.4 The number of cables in the pipe should meet the design requirements; AC single-core cable shall not penetrate the steel pipe alone.

Q: What is the main use of fireproof bridge?: Trunking is the wiring in the new house when the wiring harness together, and then embedded in a special trunking, and fixed strong, buried in the wall. This will avoid the wire exposed, resulting in electric shock. Trunk line of the Notes are as follows: 1. Wire in the slot there is a certain margin, no joints. The same circuit of the phase line and the zero line, laying in the same metal pipe slot; 3. The same power supply of different circuits without anti-interference requirements of the circuit can be Laying in the same trunking, laying in the same trunking with anti-interference requirements of the circuit with the partition isolation, or shielded wire and shield the one end of the jacket.

Q: What is the safety distance between the bridge and the bridge?: Because the strong current generated by the electromagnetic field will interfere with the weak line.

Q: How the bridge slot is connected to the ladder: Changhong TV picture-in-picture function in the remote control has a picture-in-picture dedicated button area, this area a total of eight buttons, picture in the picture to cancel the key in the CH- on the right, in the picture in the state and then click the button Is to cancel the picture in the picture.
