The need of Electric devices and tools for different types of wire is undeniable. All electrical engineers have heard the term "high voltage industrial cable". But what is a medium voltage transmission cable? Where is it used and what special functions does it have? Read on for answers! What is medium range voltage cable (MV Cable)? In electrical engineering, medium voltage cables are considered cables with rated voltages between 1000V and 30KV. The term "intermediate voltage cable" is not clearly defined. To understand what type of cable is required, we must first look at the location of the application. Where are medium voltage cables used? In the power grid, medium voltage cables are used to supply electrical energy to an area. Although they are an integral part of the grid, medium voltage cables are not used in national electricity exchanges because they maintain the voltage level between the high voltage grid and house installations. 
Larger consumers of electricity, such as industrial companies, hospitals, large swimming pools and major radio towers, often have their own medium voltage cables within the company's own substations. Since the traction network is between 15kV and 25kV, there is also a medium voltage line in use. Large systems such as cranes or transport systems also require medium voltage cables for power supply due to increased energy requirements. For these large systems, the voltage must be increased so that lower currents can be carried within the same cable, which means that the nominal conductor cross-section can be reduced. However, these types of applications require energy to be transmitted through moving parts as opposed to permanently installed power grids. Therefore, flexible cables and carriers that can transmit over long distances are essential, as medium voltage cables in these applications must be designed to handle permanent movement. There are many types of wires and cables, each designed and manufactured for a specific application, there is an important difference between wire and cable. is the number of sheaths used in it, since a wire has only one sheath, while a cable consists of two or more sheaths, the cable is designed according to the needs and existing conditions. For example, for cables used underground, the core and PVC jacket are used. A cable is a set of two or more wires, each protected by an outer layer, and the set of wires is protected by a final thick outer layer called insulation. Cables can be made flexible in terms of performance for easy installation and use anywhere. Some cables are dry and are only used for routes that do not require any flexibility. 
Now that you are a little familiar with the true power of high voltage cables in the cable definition, it is easy to describe their structure and function. High voltage cables are always used for special purposes, such as power transmission in power plants and substations, and have no ordinary or private use at all. Below are the special characteristics of this type of cable.
- High voltage cables have special properties for working with special boards or boards.
- These cables can be controlled remotely or manually from the control room.
- The smallest seams or gaps between different conductors and insulation in this cable can be very dangerous.
Depending on the voltage of the high-voltage cable, additional layers may be considered to cover this cable's insulation and control the electric field of its conductors. These cables are used for voltages of 36 kV and above. In terms of what a cable is, another type of power cable is a medium voltage cable. Such cables are usually used in mobile power plant equipment, mine installation, industrial environment, power supply, transportation system power supply and other occasions. This voltage concept is added to the electrical system as the voltage level increases. Probably the biggest difference between low and medium voltage cables is their construction. Most medium voltage cables provide some level of protection against potential stress build-up anywhere on the cable. So when we talk about the types of cables, we need to understand the differences between different cables. These cables carry voltages up to 1000 volts. 
This cable is used in industrial electrical installations, including public industry and infrastructure. Like the other examples, this cable consists of an aluminum or copper conductor, a conductor shield and an insulating shield. When we say what a cable is and what type it is, low voltage cables are also considered as one of the application categories in the electrical industry. A low-voltage cable is a cable that covers up to 750 volts. Low voltage cables are used for a variety of purposes including switchboards, industrial installations, reinforcement cables for installations at risk of mechanical attack and mobile service installations. In low-voltage cables, we can mention the following points. Armored cables: Armored cables are used for hazardous installations and protection against rodents and environmental damage. Rubber cables: These cables are used in various installations, especially as welding cables. Halogen-free cables: Halogen-free cables are very safe to release corrosive gases due to fire and are mostly used in public places. Fire-resistant cables: This series of cables is specially designed for fire and the heat generated by it, and in this case has a high resistance. Control cables: Low-voltage control cables are cables that send signals to fixed and mobile devices for control. Instrument Cables: These cables are used to transmit signals without interference in industrial equipment and facilities. Solar cable: This type of cable is resistant to sunlight and heat. Special cables: These cables are produced for special applications such as cleaning systems, lighting systems, aquariums and fountains. Aluminum cables: These cables are used to transmit electricity inside, outside and even underground. 
Medium voltage wire for electric tools
The voltage has a significant pressure and effect on the wire and it ultimately pressures the electric tools. Medium voltage electric tools are basically the equipment we use in the house. Cables are divided into different categories according to material. A cable consists of different components, each with its own material. These components include electrical conductors or conductors, insulators, some auxiliary elements found in special purpose cables, and outer sheaths. Types of cable conductors A conductor is the conductive part of a cable that carries current through it. Cable conductors are always made of two alloys, copper or aluminum, with copper being the most widely used, although aluminum is cheaper. Cable conductors come in two forms: single-conductor or single-conductor and multi-conductor cables. Cable insulation type In this part of the topic of what is a cable article, it is time to examine the types of cable insulation. The cable insulation can be made of thermoplastic material. 
Some of the most common materials include PVC, polyethylene and polyurethane. Thermal insulators are another type of electrical insulator, the most common of which are natural rubber, ethylene propylene, ethyl vinyl acetate, cross-linked polyethylene, silicone, and neoprene. Various auxiliary elements The auxiliary element of the cable can be used in two different ways, either in the form of armor or as signal protection. The armored cable has a mechanical screen that protects the cable against possible shocks. There are other types of cables that prevent signal interference from entering and exiting the cable. Type of outer sheath The outer sheath is basically the primary insulation of the cable that is visible to the naked eye. This part of the cable includes all the parts we mentioned earlier. Outer jackets are made from a variety of materials, including PVC, thermoplastic polyolefins, and chlorinated polymers. Cable type based on wire type and wire count As previously mentioned, a cable, in contrast to a single wire, consists of one or more wires. They also have internal and external insulation. The wires used in cables are produced in a variety of ways. Spray, semi-spray and wire. This part of the cable is basically the conductor of the cable that carries the current. If the wire quality is not up to standard, it may not transmit power or data properly. The cable has a certain number of wires, and the higher the voltage of the cable, the smaller the number of wires. For example, high-voltage cables have 1 to 3 wires, while low-voltage cables consist of 1 to 5 wires. 
single strand cable A single strand cable is like a single strand wire; the difference is that this cable is used instead of a wire in an environment where the risk of physical damage is high. Multi-conductor cable is very efficient, and since it has different strands, it can be used for several projects. The environment in which this cable is used should have less physical and mechanical stress. cable In front of the wire or cable is a wire type. This product is called dry cable because of its efficiency. The reason for this name is the inflexibility of this cable, since its wires are made of only one wire. Wire and cable is an industrial wire and cable that is widely used in industrial engineering. This cable consists of several wires and has little flexibility, but it currently transmits very high power. ground wire Ground cables are one of the types of cables that belong to both building cables and industrial applications. Due to the high protection of these cables, they can be used in different environments, such as wet, high humidity, dry or inside concrete. Of course, to take care of these cables, they should not be used directly in compacted concrete or basements. Shielded cable Armored and shielded cables are cables with an extra layer of protection inside. Armored cables, also known as shielded cables, use an extra layer on the inside so that they are not damaged by physical damage. Depending on the cable application, the material of this layer is aluminium, steel or galvanized. In addition, shielded cables have shields that protect data and noise. This cable is used to transfer information in systems and networks. control cable Among the types of wires and cables used in industry are command cables, which are used to transmit analog and digital information. In addition, the instrument cable is also an industrial wire and cable used in industry for data transmission and measurement and control. Semi-dispersed cable As can be seen from the name of this cable, it is between the two types of cables and wires, and has some flexibility. When they have to use a cable with some flexibility, of course they use a cable that is equipped with a cable switch. 
Medium voltage cable for electric tools
The electric tools with medium voltage cables are basically used for home-based houses. The materials used in the cables are very important to carry the voltage in. Perhaps more important than the amount of tension and the material used is the use of the cable itself. Which cable is rated for which use is a key point. Before we introduce cables by application, we need to explain that cables are divided into two categories. Examples of power transmission, we detail them and cables for data transmission in this article. Below we will describe each of these cables individually. Coax cable A coaxial cable is a cable used to transmit video, audio and image information. Simply put, coaxial cables carry electrical signals in color TV sets. These cables are of course also used in computer networks, instrumentation equipment, CCTV systems and remote control systems. We can mention the following from some coaxial cables.
- Hardwired coaxial cable
- coaxial triaxial cable
- Hardwired coaxial cable
- Radiating coaxial cable
cable This type of cable also acts as a modem or internet cable to carry certain information and data from source to destination. These cables are used to store information between networks, routers and computers. Network cables come in two forms, shielded and unshielded. Among these cables there are the following types.
- CAT5 network cable
- CAT5e network cable
- CAT6 network cable
- CAT6A network cable
- CAT7 network cable
- CAT8 network cable
telephone line Telephone cables belong to the category of telecommunication cables responsible for the transmission of audio data. These cables are used both in the air and on the ground, each with its own advantages. Telephone lines consist of 2 to 200 pairs designed to reduce noise and branching. The telephone line will contain the following elements.
- Anti-noise telephone line
- Mahada telephone line
- Fiber optic telephone line
- telephone line with jangjie wire
- self-supporting cable
A self-supporting cable is a cable designed to be installed on utility poles. This type of cable is made of aluminum conductors and polyethylene insulation in the form of cross-links or networks. These cables are used to supply and distribute electricity in airlines. These cables are produced in various forms, including the following.
- Weak pressure with aluminum rod and steel bevel
- Steel Core Aluminum Courier
- Weak pressure with zero and messenger aluminum alloy
