Comparison between high and low pressure cables

Cables: Types of low- and high-voltage cables. We will talk about them in our article about these two types and the comparison between them. Stay tuned. The difference between high-voltage and low-voltage cables  What is a high-voltage cable? The difference between high voltage cable and low voltage cable:

To transfer electrical energy in systems with voltages higher than 30 kilovolts, it is used by power generation stations to the primary and primary networks. The voltage in these circuits is very high, so it needs a lot of insulation and safety.

High voltage circuits are used to transmit electrical energy in cathode and x-ray lamps. What is weak tension cable? Low Voltage Cables Low voltage power cables are made of solid, solid or stranded copper conductors and flexible copper conductors (bare or tinned).

XLPE, PVC, LSF/LSOH and elastomeric compounds are the main insulation and protection compounds for these types of cables. Utilize wires or steel strips (or aluminum for single-core cables) under the outer jacket, providing additional mechanical protection. Cables can also be supplied for special applications, halogen cell, fire resistant, fire resistant and low smoke emission. 

Comparison between high and low pressure cables

 They are aluminum or copper cables insulated with various polymers and can withstand an electrical voltage ranging from 300 to 3000 volts. 

Low voltage cables are suitable for transmitting electricity in electric motors. Low voltage cables are divided into the following categories based on the type of conductor: 

Low-tension cables are resistant to hydrocarbons and petroleum, are fire-resistant, flame-resistant and produce little smoke when burned. What is the difference between high voltage cable and low voltage cable? Comparison between high and low pressure cables The comparison between high and low pressure cables includes the following:

 Unlike low voltage cable, high voltage cable has inner and outer semiconductor layers. An increase in voltage in a high voltage cable results in an increase in the electric field. 

In high-voltage cables, a layer of semiconductor is placed over the conductor of the wire so that the insulation meets a flat surface. Dangers of high-voltage cables: 

Comparison between high and low pressure cables

People who live near high-pressure lines risk cancer and infertility. In order to protect people’s lives from electromagnetic radiation, power line sway lines 20 kV 5 meters, 63 kV 13 metres, 132 kV 15 meters, 230 kV 17 meters 400 kilometres. The difference between the types of high voltage cables:

 The difference between high-voltage and low-voltage cables : The number of layers, the insulation material, the maximum energy of the current passing through, the type of conductor used, the branches of the conductor, and the cross-section differ for all types of high-voltage cables. 

Specifications of Low Pressure Cable The characteristics of low pressure cables are as follows: Their insulation is PVC or XLPE. These cables can be with the same center conductor or an eccentric conductor. 

The armor of weak tension cables is wire or tape. High voltage cable specifications: High voltage cables of various types have different applications in instruments, ignition systems, alternating current (AC) and direct current (DC) transmission. In all applications, cable insulation must not deteriorate due to high voltage stress, ozone, electrical discharge in the air, or trace.

 The cable system must prevent the voltage from contacting objects or other people and must control the leakage current. Cable connections and terminals must be designed to handle high voltage stress to prevent insulation failure.

High-tension cables The specifications of high-tension cables are as follows: These cables have XLPE insulation. XLPE has a crystalline structure and no impurities. High voltage cable connections:

 Connecting two high-voltage cables together leads to two basic problems. First, the outer conductive layers in both cables must be terminated without creating a field focus, such as cable end construction. 

Second, a field cell area must be created that can safely accommodate separate cable insulation and two-conductor connection. These problems were solved by the NKF in 1965 by introducing a device called the c-cuff cuff. Manual ribbon connections are the old school way of connecting and terminating cables. Making these joints involves taking several types of adhesive tape and creating the appropriate stress relief by hand.

 Some of the tapes involved can be rubber tapes, semiconductor tapes, friction tapes, coated cambric tapes, etc. This communication method is very time consuming. This requires measuring the diameter and length of the built layers. The strips often need to be semi-adhesive and pulled tightly to avoid creating windows or holes in the resulting joints.

 Application of high voltage cable The use of high voltage cables in industry is very wide, including the following: They are used to transfer electricity from power generation stations to the electricity distribution network.

These cables, with appropriate resistance, can pass high currents and will serve different locations as different voltages need to be passed. 

High voltage cable is used to transmit electricity from one city to another. High voltage cables are used in power towers, underground distribution networks and ducts. 

It is also used in factories and companies that require high effort. Features of High Voltage Cable High voltage cables work with special distribution boards. 

These cables allow remote control rooms to test systems. High voltage power cable substations reduce voltage in local areas. 

Insulators for high-voltage cables protect them from pressure and mechanical shocks and protect them from rust and oxidation. Types of high voltage cables Types of high voltage cables Regular high voltage cable Armored high voltage cable Lead and armored high voltage cables Classification of high voltage cables: 

One branch. Two branches. Triple. Four branches. Five branches. 

Types of high voltage cables: 

SF6 gas power cable. Oil power cable. SF6 cable with internal compression and aluminum tube. SF6 cable with internal pressure and steel tube. SF6 cable with external pressure and steel tubes. SF6 capsule gas cable is filled with SF6 gas. High voltage cable application. Transmission on voltage in the basement. 

Optical fiber connection. On large rigs and between cities. 

Industrial Applications: Characteristics of Low Tension Cable Cables can contain different insulating materials, which include: PVC. This insulation is mostly used in low tension cables and has the following features: Non-flammable. cheap. Flexible low-tension cables have a voltage of 1000 volts or less. 

Low pressure cable specification: Low pressure cable conductor is copper or aluminum. 

Low pressure cables have a lead sheath, which is why they can withstand hydrocarbons. 

Types of low tension cables: 

Low pressure is normal. Weak pressure protected. Weak armor pressure. Weak pressure armor. Weak bullets and armored pressure. Weak bullet, shield and armor pressure. Apply weak cable compression. Transmission of electricity through distribution lines. Lighting systems. Power generation plants. Low voltage cables Various components for cables

Low pressure:

Low voltage cable is composed of various parts, including conductor, insulation, insulation shell, conductor shell, and metal structure. 

Each has its own characteristics. Connectors are fixed-mounted cables that do not have any flexibility at all, or mobile and flexible cables. Each of these cables has a different category. For example, moving cables have Classes 5 and 6, with Class 6 being more flexible than Class 5. Low-stress cable coding: 

Meaning of letters used in low voltage cables The construction of low voltage cables is indicated by alphabetical letters, where the first letter indicates the type of conductor (N copper and NS aluminium) and the second letter indicates the insulation type (U plastic and G rubber).
