Control Cables By Swadeshi Cables: What It Is And Types

 

What are control cables?

Signal-carrying electrical cables are called control cables. They are commonly found in sectors like manufacturing, transportation, automation, and power generation.

They work by transmitting the control signals rather than power, like in power cables. Control cables are highly useful for the effectiveness and safety of machine operation. They carry low-voltage electrical signals that communicate when machines are meant to start, stop, slow down, speed up, or switch modes.

Without them, machines and systems would be unable to respond to instructions appropriately, and there would be problems like delays, and potential hazards.

They are designed to be tough and strong. They contain layers of insulation and protection to them, to avoid any signal loss, electrical noise, and physical damage.

How are they different from power cables?

Despite their similarities in looks, control cables and power cables serve very different purposes. Large volumes of electricity are transported between locations with the help of power cables. They are highly useful in supplying electricity to buildings, machinery, etc. These cables are designed to handle high voltage and current.

Whereas, very low electrical signals are carried by control cables. They aren't used for powering machines. Rather, they help in controlling them by sending instructions or signals. In short, power cables provide energy. Communication through signals is done with the help of control cables.

What is an LT Control Cable and Where Is It Used?

LT means for low tension. Electrical systems that work with low voltage, typically up to 1100 volts, use LT control cables. These types of cables are very easy to use, install, and can easily fit in small spaces.

LT control cables are suitable for short-distance or small control circuits. They are used in both industrial and residential applications. They are available in unarmoured and armoured cables to provide a level of protection which suits your installation needs.

These cables are used in:

Electrical control panels

Industrial machines

Buildings and factories

Power stations

Automobiles

However, there are some precautions one must take, like avoiding the overloading of cable even if voltage is low, and using proper insulation in moist or risky areas.

The Role of Galvanized Steel Round Wires in Cable Protection

In many types of control cables, galvanized steel round wires function as a protective outer layer. In this way, they shield the cable from physical damage, compression, wetness, and even rodents. Thus, they are well suited for outdoor or underground use.

The zinc coating on the steel will not rust and therefore allows the cable to be useful longer.

 

Some things important to know when using galvanised steel round wires are:

The main benefit of galvanized wire is the zinc coating over the steel wire which protects it from rust or corrosion. This is highly useful in harsh or outdoor conditions.

They can withstand heavy loads, wear and tears.

Galvanized wire is a more cost-efficient option as compared to other corrosion-resistant materials.

However, some precautions to take care of are:

Avoid placing these control cables near chemical spills or extremely wet surfaces.

Make sure there is proper grounding when using galvanised steel round wires.

Make sure you do not drop or treat the galvanized wire harshly to prevent scratches or damages.

What Are XLPE Insulated Cables And Its Features

Some important features of XLPE insulated cables: XLPE stands for Cross Linked Polyethylene. It is a type of strong plastic material used to cover the wires inside a cable. Unlike regular plastic, XLPE can handle heat better and does not break or damage easily.

This kind of insulation is used in both control and power cables, especially in places where the environment is hot and humid, or a place where chemicals may be present.

Some important features of XLPE insulated cables:

Works well in high temperatures

Lasts longer without cracking or melting

Resists water, oil, and chemical damage

Here are some precautions you can take while using XLPE insulated cables: Do not bend or pull the cable too tightly during installation as it can damage the wire. Always avoid using it near open flames or welding machines.

Benefits of Flexible Control Cables By Swadeshi Cables

Flexible control cables are created to bend or move without any issue. Flexible cables are perfect for machines that have a lot of constant movements like lifts, moving arms, or automated doors.

These cables are made with many small copper wires that are twisted together. This arrangement makes these cables flexible and easy to move, unlike normal rigid cables that may break if they are bent too much.

At Swadeshi Cables, we make cables that are flexible and easy to install. They are usable even in compact spaces where other regular cables may fail to work or fit.

Here are some key features of them:

Flexible control cables can handle constant movement without failing.

It is simple to use and install them in corners or curves.

The cable is less likely to be damaged over time, hence a safer option.

However, here are some things you should consider while using them. Avoid pulling or stretching the cable more than necessary. Avoid sharp bends and do not exceed the recommended curve limit, as this can overburden the cable.

How to Choose the Right Control Cable for Your Needs

Choosing the right cable can feel difficult at first, especially since they come in many types. However, if you're aware of the application for the cable and the requirement of what it will handle, it will make the choice easier.

1. Understand the voltage to be used.

Cables are manufactured to handle different voltages. For basic control systems, LT (Low Tension) cables would be sufficient in nearly all cases. They will work well in any system under 1100 volts. However, if you are using larger equipment, you should look for cables with a higher rating.

2. How often will the power cable move?

When the cable is going to be moved often like in elevators or gates, use a flexible control cable. They are constructed of finely stranded copper and will be flexible without causing any breakage or damage.

3. Where will the power cable be used?

Consider where the cable will be, inside or outside? Also consider if it is going to be in constant contact with water, dust or chemicals?

In such harsh environments, use cables with a Galvanized Steel protection. In areas where there will be heat or moisture use cables with XLPE insulation for added protection. If used outside or under ground ensure the cable is weather and water resistant.

4. Always check the quality of the cable

Verify that the cable you are purchasing follows the appropriate certifications and standards is important. Cables from companies like Swadeshi Cables are thoroughly tested and adhere to all safety standards. This means that you can trust the cables to provide you with high-quality and safe performance.

You can choose the right cable for your needs with confidence by following these easy steps, which will save you future time, money, and hassle.
