The quality and brand awareness of Rittal are good, and the application market is also large, but due to various reasons such as price, delivery time, service, etc., many customer groups do not want to use Rittal products, but choose to go to the manufacturer to order imitation Rittal products. ...

Thermal function: Due to the existence of thermal expansion and contraction, we should also pay attention to the thermal function of industrial control cables, that is, the temperature resistance level of industrial control cables, the heating and heat dissipation characteristics of cables for power transmission at working temperatures, current carrying capacity, short circuit and overload capabilities, the thermal deformation and thermal impulse resistance of the constituent materials.

In electrical switchgear, the external connection of high-current frame circuit breakers (ACBs) is usually achieved by connecting multiple cables per phase in parallel. When the conventional flat copper bar scheme is adopted, it is necessary to cut a number of bolt fastening holes on the standard copper bar to complete the connection of the cable.

China has a long history of winemaking. "Shuo Wen Jie Zi" once said: The ancients Yi Di made wine mash, Yu tasted it and was beautiful, so Yi Di was sparse. Du Kang made rice wine. Counting from the Yu period, liquor has a history of more than five or six thousand years in China, it is not only the inheritance of good taste, but also the long history of the Chinese nation.

One. The nature is different Distribution box: There is a large amount of parameter data in the distribution box. It generally constitutes a low-voltage distribution box. Control cabinet: The control cabinet is to assemble the switch cabinet, measuring instruments, protection devices and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen according to the requirements of electrical wiring.

What are the principles for drawing and reading the schematic diagram of electrical control circuits? Answer: A. The schematic diagram is generally divided into power supply circuit, main circuit, control circuit, signal circuit and lighting circuit. B. In the schematic diagram, the position of the contacts of each electrical appliance is according to the ...

1. GGD AC low-voltage distribution cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, seriality, strong practicability, novel structure and high protection level. It can be used as a replacement product for low-voltage switchgear. Structural features ...

Through continuous big data analysis of 200,000 cabinet air conditioners installed and operated on the market, Rittal found that the main problems in the actual application of air conditioners on the client are as follows: 1. Lack of maintenance, resulting in clogged air conditioner filters, which in turn causes the air conditioner to stop running or ...

With the continuous promotion of the dual carbon policy, the development of new clean energy such as wind power has been making great progress. China and United States are among the world's largest growing countries for wind energy equipment. Wind turbines typically need to operate reliably for more than 20 years to deliver electricity to people. To this end ...

1. Preparation First of all, the user should be notified to organize the cabinet without affecting the normal operation of the user. Then, according to the topology of the network, the existing equipment, the number of users, the user group and other factors, the wiring diagram and equipment inside the cabinet are outlined.

What is a Network Cabinet? The network cabinet is a kind of rectangular cabinet composed of two parts: frame and cover, which can install switches, optical fiber adapters, optical fiber distribution frames and other equipment in a cabinet, with electromagnetic isolation, noise isolation, ventilation and heat dissipation, anti-vibration, anti-corrosion, etc.

Closing faults can be divided into electrical faults and mechanical faults. There are two types of closing methods: manual and electric. Failure to close manually is generally a mechanical failure. Manual can be closed, electric can not close is an electrical fault. 1. Protection action: The protection action has been analyzed in front to trip the switch. ...

With the continuous improvement of people's living standards, more delicacies continue to flock to the market to satisfy the taste buds of foodies. However, is the food that is about to be delivered to your mouth really healthy? How to ensure the food safety and health of the tip of the tongue without foreign substances? People are concerned about the quality and safety of food production, testing, and safety.

Usage code - not marked as power cable, K- (control cable), P- (signal cable); Conductor material code - not marked as copper (can also be marked as CU), L- (aluminum); Inner Sheath Code – Q-(Lead Packed), L- (Aluminum Cladding), H- (Rubber Jacket), V-(Polyvinyl Chloride ...

1. One spare core of the control cable is grounded It has been proved in practice that when a spare core in the control cable is grounded, the amplitude of the interference voltage can be reduced to 25%-50%, and the implementation is simple, and the cost of the cable is increased very little. 2. Serious consequences will occur when electrical interference is generated.

1. It can be installed in places where dangerous gases exist, and it is safe to use the control cabinet in some environments with gas or vapor gas. 2. The shell of the control cabinet is generally made of steel plate welding or cast aluminum alloy die-casting, with high-voltage electrostatic spraying, and the whole is made of flameproof type.
