Power cables are a necessary element of power supply in the oil refining industry. They are used to connect drilling rigs, submersible centrifugal pumps and other high power power tools required for oil production and refining. Without power cables, the normal operation of oil refineries (refineries), which produce various types of fuels, oils and raw materials for petrochemicals, is impossible.
Cable requirements
If required cable for oil refining industry, you should be aware that it must meet a number of requirements. In particular, such cable products must be reliable and durable. It must also be able to withstand harsh operating conditions. These conditions include:
- high ambient temperature and heating of the cable when transmitting high currents;
- exposure to oil, water, acids, alkalis and other aggressive chemicals;
- li>
- hydraulic static pressure when the cable lies at great depths;
- mechanical damage during laying, installation or operation of the cable.
To ensure protection against these factors, force the cables are specially designed. In addition, materials with special properties are used for their manufacture.
Features of a power cable
Power cables for the oil refining industry consist of several layers. A mandatory layer is galvanized steel armor. It serves to protect the cable from mechanical damage and increases its strength. A cushion made of rubberized fabric is also needed. It is used to compensate for temperature deformations of the cable and prevent damage to the insulation.
The polyethylene sheath is also an obligatory component. It is necessary to protect the cable from moisture and chemicals. Finally, polyethylene insulation is needed to protect conductive conductors.
Depending on the rated voltage, number of conductors, conductor cross-section and other parameters, power cables may have different markings.
Power cables are an important part of the oil refining industry. They provide connection and power to various equipment for oil production and refining. This cable product has a special design that allows it to work in difficult conditions. Without power cables, the normal operation of oil refineries, which produce valuable products for the modern economy, is impossible.
