1. What are Cable Rollers?

 &#;  Cable rollers are mechanical devices that are mostly used in the construction and mining industry. Cable rollers are used to smoothen the process of installing and handling cables in a work environment. Cable rollers are used to hold the cable from the ground so that workers and pulley systems can pull them without affecting their performance.

• 2. What are man hole cable rollers and how do they work?

• &#;  Manhole cable rollers are a type of rollers that are used on the edge of holes to aid in rolling cables down a hole. Usually, they are mostly used in mining and underground construction works. They are purposely placed at the mouth of a hole in order to reduce drag that is created when pulling a cable into a duct or manholes.

•   &#;  Manhole cable rollers are shaped in a curving manner with three rollers to aid in reducing friction and traction that may occur when the cable is being pulled. Manhole cable rollers are made of different sizes and can carry different rollers of different sizes. It depends with the type and size of cable you are using.

• 3. What is a straight cable roller and where is it mostly used?

• &#;  A straight cable roller is the kind of a cable roller that is used for laying cables on trenches. Straight cable rollers are very important when it comes to laying cables. They can also be used over other cables and roll cables perfectly fine. Their main purpose is to bridge cables on trenches.

    &#;  A straight cable roller will help reduce kinks that may be formed during pulling of cables over trenches. It does not matter the difference in elevation of any side of the trench. They are made of robust materials to withstand loads of up to 300kg.

• 4. Are There any other types of straight cable rollers? Where are they commonly used?

•  &#;  Currently, we have three types of straight cable rollers. Each of these straight cable rollers has its own application but they all do the same thing

•   &#;  List type cable roller &#; List type cable rollers are used to bridge only one single cable on a trench. They resemble a single pulley system. They have many applications and can also be used to bridge a cable between any two points in a work station. They can also be used in large buildings to aid in pulling cables for installation.

•   &#;  Cable roller pulley block &#; The pulley block is a system of cable rollers that are attached together to aid in bridging two or more cables. Usually, the pulley block is made up of two to four pairs of rollers. They serve the same purpose as list type cable rollers only that they hold more cables.

    &#;  Cable roller pully block is mostly used to differentiate a set of cables from many cables. When there are many cables going over a trench, its most important to differentiate them because pulling them all together can be quite challenging and cause stress on cables and affect their performance. It's important to isolate each and every set of cables. It will also be easier to know which cables to pull, and it will also require less effort to pull them.

    &#;  Ground cable roller &#; A ground cable roller is mostly used to hold single cables to the ground. The cables can efficiently be pulled within the ground with much ease without causing any harm to them.

5. What is a triple corner roller and how is it used?

  &#;  Just as the name suggests, a triple corner roller is a type of a cable roller that is used to safely guide cables around corners and bends without causing kinks to the cable. With a triple corner roller, cables can easily be pulled without using much effort.

  &#;  The good thing about triple corner rollers is that they can be linked together with pins to extend enough to cover a corner or bend. These cable rollers can easily hold a weight of upto 300 kilograms without breaking.

6. How does a triple roller manhole pulley work?

  &#;  A triple roller manhole pulley is used to guide cables into a manhole. This type of a cable roller is well constructed to guide cables in manholes that are a bit deeper. The triple rollers are there to help a cable or a rope find its natural path into the manhole without steering off course.

7. What is a cable laying roller?

  &#;  A cable laying roller is simply a single roller that is held by an aluminum stand. The cable roller is mostly used to guide cables into a building or a work area. They are usually the last set of rollers that are used to aid the cable to reach its final end. They can easily be modified to fit in construction areas as well as other industrial uses.

8. What is a bell mouth cable roller and how does it work?

  &#;  A bell mouth cable roller is a very important cable roller, especially in situations where cables have to go through a duct. It has been specifically designed to protect the cable going through a duct as well as the duct itself.

  &#;  A split lock roller guide is specifically fitted onto a bell-like shaped conduit that can easily be attached to any conduit that a cable is supposed to go through. When a cable is being pulled through, it will smoothly pass on the roller and not touch the duct.

9. Why Should I buy cable rollers for my projects?

  &#;  Cables are very expensive to buy and it would be better to protect them. With cable rollers, you will easily pull your cables from to your desired points without using much effort.

  &#;  When electrical cables are moved carelessly within your working site, they can easily turn to be inductive or capacitive given on the number of bends and kinks the cable have. The inductive and capacitive properties can cause short circuits or provide an uneven electrical output that could easily damage your expensive electrical machines.

  &#;  Cable rollers save you a lot of time when you want to move a cable from one point to another. The rolling property makes it easier to pull cables across any surface.

10. What are the materials used to make the cable rollers?

  &#;  Our cables rollers are made of steel that has a galvanized finish or powder coating that makes them last long and endure the environment of a working site.

   &#;  Our cable rollers are made with maintenance free ball bearings.

   &#;  The rollers are made out of two materials: nylon material or aluminum alloy material. We are more than happy to customize the rollers as per your requirements.

Frequently (Not) Asked Questions About Aluminum Cables

Aluminum electrical cables are a popular wiring choice. But do you really know all about it? Here are answers to the questions you didn't know you needed to ask.

When did people start to use aluminum wiring for their homes?

Since electricity was discovered at the end of the 19th century, copper has been the go-to choice for electrical wiring. But in the s, aluminum wiring became an affordable alternative and won the competition over copper.

How are aluminum cables made?

Aluminum can be found in the earth, usually in the form of a silicate or oxide. Most often, it is sourced from bauxite, a mineral, that is further mined and refined. Refining bauxite starts with the Bayer process, followed by applying heat and pressure to it and then combining it with sodium hydroxide. Lastly, the mineral is smelted, which creates 99.8% pure aluminum. For aluminum wiring, the received pure aluminum is molded for sale to manufacturers, who then draw it to create thin, long and flexible wires.

How do I choose between aluminum and copper wiring?

The choice depends on several factors. For example, aluminum wires are more affordable, lighter and provide higher impedance. They are also bigger than copper cables with the same ampacity. At the same time, aluminum cables are less elastic and conductive.

Do I need a connector for aluminum conductors?

Yes, you need connectors labeled with "AL," which stands for aluminum. These come in a variety of types, so look into the product range to get the right one. 

What maximum length of an aluminum cable can I get?

Aluminum can be as long as you need it, just make sure to get the correct measurements.

How safe is aluminum wiring for the home?

Aluminum wire is completely safe for use in houses if it is installed properly. 

How to make aluminum wires last?

Since aluminum cables are prone to mechanical damage, make sure to avoid bending your wiring during installation. It's best to prevent any rubbing, too. Another crucial thing to keep in mind is that instructions for installation and usage need to be followed strictly &#; installing your wire in an unsuitable environment can lead to overheating and hence, faults.

How to identify aluminum wiring?

Aluminum wires are quite easy to identify &#; they are the color of aluminum and marked with "AL" on the jacket, which stands for "aluminum." If you know that a house you're at was built between and (in the US), the wiring used in it is most likely aluminum. In houses built later, you can also find "CO/ALR" marks, which stand for "copper/aluminum revised" and imply that it is an aluminum wire with a binding terminal.
