1. Look at the packaging, the wires of the national standard are often better, neat, and have a sense of quality when you hold them. 2. To open the package and take a look at the wires inside, the wire requirements of the national standard wire 1.5——-6 square are required to be skin thickness (insulation thickness) is 0.7mm, and too thick is non-standard.

Power system The wire and cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper power cables, which are basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables, branch cables (replacing part of the busbars), ...

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 ...

1. When the cables cross each other, the high-voltage cable should be below the low-voltage cable. If one of the cables is protected by a pipe or separated by a partition within 1m before and after the intersection, the minimum allowable distance is 0.25m. 2. When the cable is close to or crosses the thermal pipeline, if there are thermal insulation measures, the flat ...

1. TPE material has soft touch, high elasticity, mild texture, adjustable surface gloss and fog brightness, low smoke and halogen-free, phosphorus-free, excellent oil resistance, weather resistance, aging resistance, flex resistance, ozone resistance and chemical resistance. 2. The old TPE material can be simply recycled and recycled.

1. External force damage. Judging from the operation analysis in recent years, especially in Haipu East, which is developing rapidly, a considerable number of cable failures are caused by mechanical damage. For example, the cable laying and installation is not standardized, which is easy to cause mechanical damage; Engage in civil engineering on directly buried cables ...

The operating voltage of the cable Generally speaking, there is a certain relationship between the operating voltage of the cable and the rated voltage. If some cable lines are not in use, they must be connected to the power grid to ensure that the cable lines are not exposed to moisture. When the neutral point is not grounded ...

Classified by voltage level According to the voltage level, it can be divided into medium and low voltage power cables (35 thousand volts and below), high-voltage cables (above 110 thousand volts), ultra-high voltage cables (275-800 thousand volts) and ultra-high voltage cables (1000 thousand volts and above). In addition, it can also be divided into AC ...

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. 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.

Reliable supply wherever you are Tesvolt's large-scale industrial battery storage systems are based on standard products made by Rittal and guarantee a continuous power supply on the top of a mountain, by the sea or in the desert. The mountain peaks rise high above the crystal clear ...

The power of the 10 billion market 　　With the help of continuous favorable policies, China's new energy vehicles have maintained rapid growth this year. According to data from the China Association of Automobile Manufacturers, the production and sales of new energy vehicles reached a new high in October, with a year-on-year increase of 87.6% and 81.7% to 762,000 and 714,000 units, respectively.

1. The cabinet is generally made of cold-rolled steel plate or alloy to store the computer and related control equipment, which can provide protection for the storage equipment, shield electromagnetic interference, arrange the equipment in an orderly and neat manner, and facilitate the maintenance of the equipment in the future. Cabinets are generally divided into server cabinets, network machines, etc.

The model of the power cable 1. Use the capitalization of the first letter of Hanyu Pinyin to indicate the type of insulation, conductor material, inner sheath material and structural characteristics. For example, Z is used to represent paper (zhi); L stands for Aluminum (LV); Q is for lead (qian); F stands for fen; ZR stands for Flame Retardant (zura...

Short-circuit fault: There are two-phase short circuits and three-phase short circuits, which are mostly caused by hidden dangers left in the manufacturing process. Grounding fault: one or more cores of the cable break down to the ground, and the insulation resistance is lower than 10kΩ is called low-resistance grounding, and higher than 10kΩ is called high-resistance grounding. Mainly due to cable corrosion, lead ...

Sincere service, strength and responsibility In 2022, which was full of changes, Rittal and its partners Hengxin Software and Yokogawa Automation (part of the Yokogawa Group) withstood the challenges brought about by the pandemic and moved forward hand in hand. In the cooperation project, Rittal worked with the customer to overcome difficulties and complete the project delivery in a timely manner, ...

External damage: In the process of storage, transportation, laying and operation of cables, they may suffer external damage, especially the directly buried cables that have been run, and are prone to damage in the ground construction of other projects. Such accidents often account for 50% of cable accidents. In order to avoid such accidents, in addition to strengthening the cable ...

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 ...
