What is Low Voltage Cable?
A low voltage power supply is 600 volts AC or less. Typically used in factories with automation. Low voltage is split into supply and control for better use. Low-voltage wiring refers to electrical cables and accessories used in applications that require less infrastructure, such as telephones, security wiring, fire alarms, intercoms, and internet. The safety, reliability and speed of business activities are affected by the laying of low voltage cables. Low voltage cable insulation and shielding materials include low voltage XLPE cable, PVC, LSF/LSOH, and elastomer compounds.
The types of low voltage cables are
Alternating Current (AC)
A characteristic of this type of current is that the direction in the conductor changes periodically and the current reverses. AC power is a safe solution for your home and commercial electrical needs.
Direct Current (DC)
This current carries electricity in a straight line. The most common type of battery is the DC.DC, suitable for smaller projects.
Working of a low voltage cables
Electrical equipment with low voltage cable ratings of 50 to 1000 V AC and 75 to 1500 V DC are connected by low voltage (LV) cables. As a result, the electrical load is relieved. Wiring with low voltage cables requires the knowledge and experience of a highly qualified technician to install. of the entire network of common power cables in the building. Low voltage life is safe.
In certain circumstances, the cabling infrastructure must be configured to support lower voltage sizes. Low voltage cables have several advantages, such as their versatility in almost any type of surrounding construction. Some of the most common low voltage applications include:
telephones are required in both multiple telephone systems and computer networks. They are still important in every organization and home office. Cable connections often include configurations based on fiber, Ethernet, or WiFi.
Wi-Fi is available on almost every device in the office these days. Wi-Fi network setup uses low-voltage electrical wiring.
Line demand in commercial buildings is high. Laying low-voltage cables is becoming more and more profitable and cost-effective. Low voltage wire gauges are used for video and audio equipment and are increasingly being used by companies subscribing to cable television.
Types of low voltage cables
- A fiber optic cable that helps connect your computer to the Internet
- Cat5 and Cat6 cables to handle Ethernet connections
- RG-6 cable to handle internet connectivity in addition to cable and satellite TV
What is Medium Voltage or MV Cable?
Medium voltage cables are cables with a nominal voltage between 1000 V and 30 kV. However, the term “medium voltage cable” is not clearly defined. To understand what type of cable you need, you first need to find out where your application is.
Where are Medium Voltage Cables used?
Within the grid, medium voltage cables are used to supply electrical energy to the area. Medium-voltage cables are an integral part of the distribution grid, but they are not used for nationwide power exchange as they maintain voltage levels between the high-voltage distribution grid and household appliances. Large power consumers such as factories, hospitals, large swimming pools, and large radio towers typically have their own medium-voltage cables within their company’s substations. The traction current network is between 15kV and 25kV, so medium voltage lines are also used.
Medium voltage structures are usually configured as follows:
- Aluminum or copper conductors,
- Conductive Shield – Usually made of some kind of semiconducting material.
- Insulating screen. This can be semiconducting or metallic braid or tape.
Construction and Materials The construction of medium voltage cables can be of various sizes and type
The construction is much more complicated than that of low voltage cables.
The difference between medium voltage and low voltage cables lies not only in the type of cable construction, but also in the manufacturing process and the raw materials used.
The insulation method for high voltage cables is very different from that for low voltage cables. That is: The medium voltage insulation process is achieved by using a CCV line instead of a traditional horizontal extruder, as in the case of low voltage cables.
What is High Voltage or HV cables?
High voltage refers to the amount of voltage output above normal standards or thresholds. There are two points about high voltage that describe its nature. It creates sparks in the air and the fact that you can get electrocuted if you get too close. The voltage can affect his two conductors of the system, or one conductor and ground. For example, when it comes to power transmission, voltages above 35,000 volts are considered high voltage. Device design and isolation are essential to its classification.
Voltages above 50 volts are considered dangerous to living organisms, emphasizing the need for more safety and for circuits to meet safety standards. Voltages above 1000 volts are also high voltages. With this in mind, High Voltage or EHV is voltage in the range of 345,000 to 765,000 volts.
High voltage cable features
High Voltage Cables have special properties and work with certain switching and distribution boards. Allows control room switching and remote control or manual testing of individual supply systems.
High Voltage Cable Substation can lower the voltage and distribute it to the area.
The semiconductor layer should be seamless and should be a few microns. Crevices and spaces between layer fusion and insulation are very dangerous.
Industrial cable types are usually high voltage cables. The main reason for this is that higher voltages require less current to power the same number of devices. This means less heat is generated and easier to manage and control. Another reason high-voltage cables are used in industrial applications is that power outages are less likely.
How to identify the type of cable- full guide
Identifying the power cord type can be difficult without the proper knowledge and tools. There are several ways to identify a power cord, but the most common is by looking at the markings on the cord. Markings on the power cord typically include the following information:
- Manufacturer’s name or logo
- Voltage value
- ladder size
- Insulation type
- jacket type
Now that you know the basics of power cord types, it’s time to buy the right one for your project. Power cords are available in a variety of sizes, voltage ratings, and insulation materials. Choose a power cord rated for the required voltage and amperage. When in doubt, always seek professional help.
