How to wire the distribution frame is an important issue in the use of the distribution frame. Correctly solving how to wire the distribution frame is an important guarantee for users to use the distribution frame.
To understand how the patch panel is wired, we must first clearly understand the concept of the patch panel. The distribution frame is an important supporting equipment in the management of the integrated wiring system. The distribution frame is mainly used for the fiber fusion splicing of the optical cable terminal, the installation of optical connectors, the adjustment of the optical path, the storage of excess pigtails, and the protection of optical cables. The safe operation and flexible use of communication networks play an important role.
In addition, we have to sort out the wire sequence of the cables to solve the problem of how to wire the patch panel. Under normal circumstances, there are a total of 25 cable sequence, which can be divided into five groups:
The first group: white blue, white orange, white green, white brown, white gray;
The second group: red and blue, red orange, red green, red brown, red gray;
The third group: black blue, black orange, black green, black brown, black gray;
The fourth group: yellow blue, yellow orange, yellow green, yellow brown, yellow gray;
The fifth group: purple blue, purple orange, purple green, purple brown, purple;
After clarifying the wiring sequence, you can wire it up. How to wire the patch panel?
The specific steps of how to wire the patch panel are as follows: According to the number of pairs of large pairs of cables to be connected, wire the patch panel group by group in the order of the ribbon. When wiring the patch panel, first separate the wires according to the color order of the ribbons, such as 1-25 for the white and blue group, 26-50 for the white and orange group, and arrange them in order. Then take out one of the 25 pairs and divide them into five groups in the order of white, red, black, yellow, and purple, starting with the white group, white, blue, white, orange, white, green, white, brown, white, Gray; Next play the red group: red, blue, red, orange, red, green, red, brown, red, gray; play 25 pairs in turn. When wiring, first put the line card on the line position, then use the wiring to press the line into the line position, and finally put the patch panel module on the shelf.
Storage Tank Water Heater
A storage tank water heater is water-heating container that uses a large tank to store hot water until it is needed. This type of water heater is typically powered heating steam or gas, and is used to provide hot water for a variety of uses, including showers, dishwashing, and laundry, or other hot water requests alike. The tank is typically insulated to help maintain the water temperature and reduce energy costs. Storage tank water heaters are a popular choice for many households because they are relatively inexpensive and can provide hot water for multiple uses.
Typical heat exchanger structure is heating spiral coil inside of a steel shell. Water will be heated while passing through inside the coil, and received the energy or heat from hot steam or gas.
The main disadvantage of a storage tank water heater is that they are less energy efficient than tankless water heaters. This is because they continuously heat and reheat the same water, which can waste energy. Additionally, storage tank water heaters require more space than tankless water heaters, as they are larger in size.
In that sense, recent years are seeing storage tank water heat exchanger giving way to other efficient products, such as Shell And Tube Heat Exchanger, Plate And Frame Heat Exchanger, and so on.
