Electric Cable Cutters

Introduction

In the ever-evolving world of electrical work, the tools of the trade are as crucial as the skills of the electrician. Among these tools, electric cable cutters stand out as an indispensable asset. Designed to cut through various types of cables, these tools are engineered to make jobs quicker and easier. This article delves into the importance of electric cable cutters, the different types available, and how to choose the right one for your needs. We also explore their proper usage, maintenance, and the safety measures to consider when handling these tools.

The Importance of Electric Cable Cutters

Cable cutters are a staple in the tool bag of many trade professionals. While all cable cutters are essentially designed for the same task of cutting various cables, the way they are engineered can make certain jobs quicker and easier. This highlights the importance of having the right cable cutter for the job.

Different Types of Electric Cable Cutters

Electric cable cutters are essential tools commonly used in electrical applications. They are typically insulated to prevent electrical shocks. It's crucial not to mistake the plastic or rubber coating on the levers of a non-insulated cable cutter for electrical insulation. Another type is the hydraulic cable cutter, used on various conductors, wire ropes, and even solid bars. They feature a guillotine-style head shear to minimize jams and are primarily used in the power utility and electrical industry for cutting copper or aluminium power cables and overhead conductors.

Manual Cable Cutters

Manual cable cutters, also known as wire pliers or wire cutters, are essential tools for twisting, clamping, and cutting wires, cables, and ropes. They can operate with electricity and cut general metals. The quality of these tools is judged by their appearance and internal structure. A good manual cutter has a beautiful and elegant appearance, with the mouth and blade aligned. Internally, the cutter's shaft should be flexible and the blades moderate. When cutting steel wire, it should be easy, without the jaw blocking or deforming. The intrinsic quality of these cutters lies in their quenching process. Therefore, when buying, check the appearance, ease of use, weight, and the condition of the insulation glue.

Hydraulic Cable Cutters

A hydraulic cable cutter is a powerful tool ideal for cutting through heavy-duty electrical and power cables, typically used in construction and shipbuilding projects. They attach to an external pump, with the most capable models able to cut diameters up to 7.09” (180mm). The external pump not only provides the cutting power but also helps to keep the tool cool during repeated operations. While they are highly effective for large diameter wire ropes, hand-held cutters may be a more suitable choice for smaller diameter cables.

Battery Operated Cable Cutters

Battery-operated cable cutters are a powerful tool, ideal for on-site electrical work. They're designed to cut aluminum and copper cables up to a maximum diameter. This cordless cutter is equipped with a two-stage hydraulic system, ensuring a quick turnaround time. A unique safety feature is its ability to automatically open the shears when the maximum pressing force is reached, preventing overload. This makes it an excellent choice when dealing with thick power cables that often need cutting.

How to Choose the Right Electric Cable Cutter

Choosing the right tool for cutting cables is crucial. Using the wrong tool can damage the insulation, conductor, or even the tool itself, leading to an increased chance of corrosion or loss of conductivity. Cable cutters, especially ratcheting cable cutters, are designed to cut through a wire with as little effort as possible, making tasks like cutting 4/0 AWG an easy task. The ratcheting action ensures consistent and almost effortless cuts. These tools are known for their repeatable accurate cuts, making them an essential tool for modern electricians.

Considerations Based on Cable Type and Size

Choosing the right cable cutter depends on the type of installation and personal preference. Cable cutters come in various shapes, sizes, and capabilities, each designed for specific jobs involving different types of cables such as copper, aluminum, telephone, TV, or coaxial cable. They generally fall into four categories: shear-action handheld types, longer-handled two-handed cutters, ratcheting cable cutters, and power-assisted cutters. Each type has its unique strengths and applications, and no two pairs of cable cutters are alike.

Evaluating Durability and Ease of Use

The durability and ease of use of electric cable cutters are crucial factors to consider. High-quality tools are designed to cut through metal with minimal effort, ensuring consistent and almost effortless cuts. Misusing tools can lead to damage to the tool itself, the insulation, or the conductor, increasing the chance of corrosion or loss of conductivity. Therefore, choosing tools known for their repeatable accurate cuts and designed for specific tasks can enhance the longevity of the tool and the quality of the work.

Safety Features to Look For

Safety is paramount when handling electric cable cutters. The small copper strands can puncture your skin or cut you when you cut copper cable. Always wear safety glasses to protect your eyes from flying pieces. The cutting and crimping tools can be dangerous if not used properly, so always read the documentation that comes with the tool. Remember that copper cable conducts electricity, so always test the cable with a voltage detector before touching it.

Proper Usage and Maintenance of Electric Cable Cutters

When using electric cable cutters, safety should always be your primary concern. Always cut at a right angle to the cable, and never apply too much force. Regularly check your cutters for damage and replace them if they become dull or cracked. Maintaining your cutters will ensure their longevity and efficient performance. Clean your cutters after each use to remove any debris that could dull the blades. Lightly oiling the hinge can help prevent rust and ensure smooth operation. If the cutters become dull, it’s often possible to sharpen them using a fine file or whetstone, but follow the manufacturer’s instructions or consult a professional if you’re unsure.

Safe Handling and Operation

Hydraulic cable cutters, a type of electric cable cutter, operate under high hydraulic pressure, making them a versatile tool. However, this high pressure necessitates careful handling and maintenance. The amplification of relatively little manual power into a greater hydraulic cutting force not only eases the task but also enhances safety and precision. Nevertheless, certain precautions before and during tool use are essential for safe operation.

Routine Maintenance and Care

Proper maintenance of electric cable cutters is crucial for their longevity. After use, especially outdoors, they should be cleaned thoroughly to remove dust and other substances. If stored for a long time, a dry rag can be used for cleaning. In case of glue residue on the cutter, common household items like lotion or face oil can be used to remove it. However, avoid disassembling the tool or knocking it, as it may affect the internal structure. Regular maintenance not only prevents unnecessary trouble but also extends the life of the cable cutter.

Conclusion

In conclusion, electric cable cutters are an essential tool for modern electricians, offering a range of options to suit different tasks and cable types. Choosing the right cutter is crucial, taking into account the cable type and size, the tool's durability, ease of use, and safety features. Proper usage and maintenance of these tools are equally important, ensuring their longevity and efficient performance. Safety should always be a priority when handling these tools, with careful attention to the manufacturer's instructions and guidelines. By understanding these aspects, electricians can ensure they are equipped with the right tools to deliver quality work safely and efficiently.
