Rittal cables – type descriptions for power cables

1. When the electrical cabinet is used, the shell should be reliably grounded, and the electrical parts should be comprehensively inspected to eliminate the phenomenon of leakage and open circuit that may be caused by long-distance transportation, and check whether the voltage is consistent with the working voltage. 2. The electric cabinet is a non-explosion-proof oven, so it is flammable, explosive, volatile and corrosive.

Product Introduction Product name: Rittal Rittal Product Type: Rittal Non Woven Filter Mats Product Model: 3172.105 Spare filter mats for top-mounted fans, filter fans or thermoelectric coolers to protect control cabinet components from dirt, ash ...

1. Core: The core is the conductive part of the power cable, which is used to transmit electric energy and is the main part of the power cable. 2. Insulation layer: The insulation layer is to electrically isolate the core from the ground and the cores of different phases to ensure the transmission of electric energy.

The power cable is used to transmit and distribute large-scale electrical energy in the main line of the power system, and the control cable directly transmits the electric energy from the distribution point of the power system to the power connection line of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6/1KV and above, and the control cables are mainly 4 ...

1. It should have good technical performance. The structure of the cabinet should be designed according to the electrical and mechanical properties of the equipment and the requirements of the use environment, so as to ensure that the structure of the cabinet has good stiffness and strength, as well as good electromagnetic isolation, grounding, noise isolation, ...

What are the precautions for using current transformers? Answer: 1. The secondary side shall not be open when working; 2. One end of the secondary side must be grounded; 3. The polarity of the terminal should be paid attention to when connecting. What are the precautions for using voltage transformers? A:1. When working, its secondary side shall not be short-circuited ...

1. The weight of the cable in the industrial control cable drag chain should be evenly distributed, so as to avoid accidents caused by uneven weight during operation, and the principle of distributing the cable is that the heavier one is located on both sides and the lighter one is located in the middle. All industrial control cables must be securely fastened to one end of the energy chain, so that ...

1. Site selection. The location of the low-voltage distribution room should be close to the load center, set up in a place with less dust, less corrosive medium, dry and slight vibration, and should appropriately leave room for development; Second, the layout of power distribution equipment. The layout of the distribution equipment in the low-voltage distribution room must follow the principle of safety, safety, and safety.

Wire surface marking - according to the national standard, the wire surface should have the manufacturer name, product model and rated voltage continuous marking. This is conducive to finding the manufacturer in time when problems occur during the use of wires, and consumers must pay attention to this when purchasing wires. At the same time consume ...

What is the role of a DC system in a substation? Answer: The DC system provides reliable DC power supply for control signals, relay protection, automatic devices and accident lighting in the substation, and also provides reliable operating power for operation. The reliability of the DC system has a significant impact on the ...

1. In principle, the power cord and network cable of the cabinet should be sorted out separately; 2. The placement of the equipment should be appropriate, avoid squeezing each other, avoid being too high or too low, and avoid being too close to each other; 3. If there are too many devices in the cabinet, the equipment should be numbered; 4. For each line ...

1. Buried laying The laying method of laying the cable immediately underground is called buried laying. The buried cable must be armored cable and anti-corrosion coating protection cable, and the bare cable cannot be buried. Generally, the depth of the cable trench shall not exceed 0.9m, and the buried laying shall be paved ...

1. Determine the size of the server, such as depth size, height size (how many U), and whether it is a 19-inch rack-mounted installation. 2. Choose a cabinet according to the installation space: If the server is a 19-inch rack-mounted installation, then a standard cabinet can be used. Root...

Alarm code: A01 System message: Open the cabinet door The cause of the Rittal air conditioner: the opening and closing of the door is not in the correct position Diagnostic method: Check the changing position of the door and, if necessary, the connection status Alarm code: A02 System message: The temperature in the cabinet is too high ...

1. It occupies a small area. Generally, it is buried in the soil or laid indoors, ditches, tunnels, with a small insulation distance between lines, no towers, less land occupation, and basically no land on the surface. 2. High reliability. It is less affected by climatic conditions and surrounding environment, and the transmission performance is stable and the reliability is high. ...

1. The impact of lightning The armor components of the control cable are all metal conductors, and if the power line is short-circuited or lightning hits the metal parts, a strong current will be generated to destroy the optical cable line equipment, and even casualties will occur in serious cases. 2. Optical cable ...
