What is a High Pressure Cable?
High-voltage cables that can pass currents of more than 30 kilowatts are called high-voltage cable or power cable (HV: high-voltage cable). In general, these cables are used to transmit electrical energy at high voltage. These cables include a conductor and an insulator. This means that these cables have a complete insulation system, which consists of semi-conical layers and a metal shield.
Use of high pressure cable
The structure of power cables is different according to their application. In addition to transmitting electricity at high voltages, this type of cables has other uses, including the following: High voltage transmission in the basement Connecting optical fiber On large and intercity rigs Industrial applications
What is a poor pressure cable?
Low voltage (LV) low voltage cables have a voltage range of less than 3 kV. This category of cables can be divided into different categories according to the type of materials used in the insulation and their coating, such as PVC insulated low pressure cables, XLPE insulated low pressure cables and also fireproof low pressure cables. show
What is the electricity?
Surge arrester is a device that is used in electrical networks to protect equipment against damage caused by sudden overvoltages such as lightning and lightning. Lightning arrester shows a very high resistance to the level of electrical insulation against normal voltages and shows little resistance against instantaneous voltages and discharges electric waves to the ground. Surge arresters provide the best protection compared to other protective devices and provide the greatest amount of transient wave removal. Surge arresters are placed in parallel with the device under protection or between the phase and the ground. The energy of the overvoltage wave is transferred to the ground by the arrester.
