Voltage is known as electric potential difference or electric pressure and refers to the difference in electric potential between two points. Vital tasks are not possible without voltage. Below are the voltage classifications.

High-voltage electricity

High-voltage electricity is ordinary in transmission from the power plant. Power is transferred at this level to increase efficiency. 

Lower current is coupled with higher voltage transmission to allow thinner and lighter cables. Using thinner and lighter cables helps reduce building towers and power lines costs. Higher voltages are around 115,000 to 230,000 volts AC.

Ultra-high voltages range from 345,000 to 765,000 volts AC. Electricity is transmitted at more than 450,000 volts of alternating current in the United States. High-voltage transmission is done through quality switching and distribution boards. In addition, control rooms should have additional switching capability. Very high voltages range from 765,000 to 1,100,000 volts AC. China is developing a 1,100,000 V alternating current system.

Application of high-voltage electricity

Many devices and equipment in various industries (for example, medical industries) require high-voltage power sources.

Old sources were made in very high dimensions and weight, and their repairs and equipment were time-consuming.

But today, with the progress of power electronics, the dimensions of these sources have become very small, and on the other hand, the quality of the voltage provided by the high voltage power supply is much more favourable than in the past; in a way that has made the use of related equipment much more effortless.

High voltage power supply is used in research, ozone and plasma production, oil, gas and petrochemicals, pharmaceuticals, cosmetics and hygiene, food and agriculture industries, environment, medicine and treatment, textile and fibre industries, and gas and solid state lasers.

One of the most critical applications of this device is ozone production and water and air purification.

This type of power supply also covers primary and other areas, which we briefly mention below:

• Semiconductor manufacturing equipment

• Plasma and vacuum equipment

• Medical Equipment

• Setting up the X-ray lamp

• Electrostatic induction

• Ion filters to remove harmful gases

• Dielectric resistance tests

• Ion and electron accelerators

• Electron gun

• Beam detectors

• Electrostatic paint

Safety measures

Since high voltage can be dangerous, proper safety precautions are essential when working with it. Low and high voltage refers to the intensity at which electricity is sent through wires. The low voltage causes less damage, while the high voltage is more dangerous. While low voltage is generally safe, you should still take some safety precautions when using it. For example, when working with soft voltage power lines, it is imperative to ensure that they are not exposed to damage. Working with high-voltage power lines is more dangerous. Therefore, you should be more careful when working with them. In addition to ensuring that they are not exposed to harm, it is essential to wear protective clothing and avoid contact with them.

Low-voltage electricity

Low voltage is divided into the power supply and control for better use. A low-voltage power source is equal to or less than 600 V AC. It is usually used in factories that use automation.

Low-voltage electricity applications 

While high-voltage power is suitable for transmission lines and factories that use a lot of electricity, most electrical devices in homes and offices run on low-voltage power. The use of low-voltage direct current has a lot to offer. For example, using low-voltage electrical devices reduces costs and increases safety. A low-voltage power supply also improves energy efficiency. Most renewable energy sources, including solar, hydro, and wind, provide low DC power.

Combination of low and high voltage power for increased performance

However, some devices use a combination of low-voltage and high-voltage power to increase performance. Although, demand is shifting towards low-voltage systems, especially in lighting. The introduction of light-emitting diodes is an excellent example of this change. Pathway lighting that uses accent lighting is also an example of changing demand. Low-voltage electrical systems have also become popular because they generate less heat than high-voltage electrical systems. Reducing heat allows us to save energy by reducing the need for cooling.

Installing low-voltage electrical wiring is also less complicated than high-voltage wiring. Any skilled electrician, like the experts on the KCS Group, can install low-voltage wiring. Low-voltage wiring is much safer to install than high-voltage wiring. Low voltage lighting also conserves backup batteries as they run on low power. In addition, some light-emitting diodes have emergency backup drivers.

Electric cable and industrial cable

Power cables are used for industrial power cabling and for the transmission of electric power and consist of three main components: one or more solid or stranded copper or aluminum conductors, insulation and an outer sheath that holds everything together. Depending on the intended application, they are available in various shapes, sizes, and materials.

How to choose the right type of cable

When selecting power cable for use in industrial power cabling, there are two main factors to consider: 

1. Current capacity, which is determined by the cross-sectional area of ​​the core on the cable 
2. The operating environment 

This material determines the outer sheath and insulation, and you must pay attention to the usage conditions of the cable.

What type of cable is used in industrial settings?

All kinds of cables are used in industrial settings for networking, power transmission and communication. Coaxial, data, and instrumentation cables are some of your most typical designs. These low-voltage cables are usually rated for 2000 volts or less power distribution. 

Low-voltage wires are typically made with copper or aluminum conductors as single or multi-conductor strands, bundles or knotted strips. These cables provide transient DC or AC power to generators and motors in machinery such as conveyors, power tools, robotics, and other large machines. They are also available in flat structures from moulded materials. Their construction usually includes protection, hard coating, insulation, and filler materials to withstand mechanical loads, high speeds and accelerations, and harsh indoor and outdoor environments.
