SINGLE USE SOLUTION FOR WIRE PULLING

SINGLE USE SOLUTION FOR WIRE PULLING
HOUSTON, TX – RectorSeal introduces a new, low cost single use device for pulling wire. Simple- Easy- Reliable- Durable. RectorSeal® Single-Use Wire Grabber™ is used once, and is then recycled along with the scrap wire. 

This innovative tool is ideal for contractors who do only occasional wire pulls. It is an economical alternative with a low initial cost that will save Electrical Contractors on labor hours and drastically reduce the cost of setting up multiple wire pulls. Set-up time for a 4 wire pull is less than 5 minutes. This allows an Electrical Contractor to pull four times as much wire within a day.

The RectorSeal® Single-Use Wire Grabber™ is available in 18 sizes (8 AWG through 1000 mcm) to be used in sets to accommodate jobs of different sizes. Works on 600 volts through 35 KV wire and rated for both copper and aluminum wire. The lanyards are available in a variety of lengths to make staggering multiple wire pulls effortless especially through and around nineties. The small pulling head reduces friction; therefore there is no need to oversize conduit to accommodate the pulling head. 

Pulls are made by stripping the wire jacket back 3 inches and then, crimping the lug with 2 crimps on the wire using a hydraulic die or dieless crimper, and then start pulling. Strip it, Crimp it, Pull it – it is that easy!      

RectorSeal® Single-Use Wire Grabber™ innovative, labor saving tool for electrical contractors is now available through RectorSeal’s® nationwide distribution network or by calling customer service at 1-800-231-3345. 

Founded in 1937, RectorSeal® Corporation is a leading manufacturer of chemical and specialty products designed for professional tradesmen.

Ratcheting Wire Cutters

Wire Cutting ToolsFor those who work with cables and wire, wire cutters are indispensible tools of the trade. Whether cutting WG8 or 1000 MCM cables, you need tools that are strong enough to do the job but careful enough to make precise cuts. When you are looking for wire cutting tools, whether dedicated or universal, try to get the best quality you can afford. This extends the life of your tool and ensures that you will get the best results.

How do you choose the right tool for your needs. The first thing to take into account when choosing a wire cutting tool is the limitations of the particular cutter. You have to pick one that will cut the maximum gauge of wire you are using.

If you try to cut a 12 gauge wire on a cutter that’s only rated for 18 gauge, you’ll ruin the cutting edge of the tool and wind up with a messy end on your wire. Cutting through cable requires a tool with strong jaws and sharp edges. There are many types of cutters: diagonal cutting pliers “dikes” are small wedge-shape cutters, one side of the blade is flat and the opposite is curved for cutting wire flush with surfaces best for cutting through small individual wire. Wire Cutters slice through individual wires and sheathed electrical cable with a long thin cutting blade. Cable cutters cut through thick electrical cable with 2 C-shaped cutting heads attached to straight, hinged handles. Ratcheting cable cutters reduces the amount of muscle power required to cut through thick cables. Like standard cable cutters, the ratcheting cable cutter consists of cutting heads and hinged handles. The ratcheting cable cutter’s heads, however, remain locked in place following the compression of its handles. With every compression of its handles, the ratcheting cable cutter grips and bites a cable. As such, the ratcheting cable cutter relies not on short, strong bursts of strength but repeated, firm pushes this ratcheting action helps to cut thick cables much better than trying to use strength with a pair of snips.

If you have never used a pair of ratcheting cable cutters, here are some steps to take to use them properly.

The first step to working with a ratcheting cable cutter is to become familiar with it. Look over the tool, see how the ratchet works, become accustomed to the release mechanism, and try it out without any type of cable. This works much like that of a handcuff. The jaw opens up so that you can insert the cable into the cutting area.

Once the cutter is opened, you can then close the ratcheting cutter around the cable. Make sure it locks into position so that when you depress the handles, the ratcheting action will start to work. Keep the cutter at a perpendicular position to the cable. This will help make a cleaner cut and lessen the chance of any type of injury.

Now that the cable is positioned in the cable cutter, you can begin the process of cutting through the cable. Do not be surprised if it does not go through the cable in one slice. The ratcheting action of the cutter is there to help power through larger diameter cables in smaller cuts. The pressure of the ratchet, as the cutter clamps down on the cable, keeps the blade working through the cable.

As you begin to cut through the cable, you will continue to ratchet the cutters until you have a clean cut.

Clean the blade of any remaining residue.

And remember to always wear eye protection when using any wire cutter.

Tools for Electrical Wire Pulling

electrical wireWires are defined as insulated conductors used to carry electricity. Most commercial buildings have wires and cables running through walls and above suspended ceilings to provide basic electricity, telephone service, high-speed data and video connections, and operate building controls and security systems. Electricians need a way to run this wire and cable through walls and conduit.

For residential and light commercial work, most wires can be pulled manually. Power-pulling tools are however, needed for larger wire with long runs and multiple-cable installations. Long runs usually have multiple bends which make it almost impossible to pull manually.

A pulling tool’s basic components are its frame, power source, capstan that pulls rope and wire, and the mechanism that turns the capstan.

These components today are the same as those of the first power puller introduced by Ensley Tools in the 1960s, but improved technology has made today’s pullers more powerful, versatile, easier to use, and safer. The first pullers trend was bigger was better and stronger, but now the market is seeking smaller models. The user wants self-contained equipment, one machine that operates many functions to handle a wide range of jobs.

Light duty pullers are small, self-contained and can be carried by one person. These cover 80% of the pulls found in commercial building projects. When pulling the frame is attached to the conduit attached to the electrical panel box eliminating the need attach it to the floor.  Most have two pulling speeds: fast and slow (for heavy pulls). Large pullers generally need to be bolted to the floor.

Cable-puller capabilities are defined by pulling force, stated in pounds or kilonewtons (kN); pulling speed in feet or meters per minute; and rope strength, defined by average breaking strength.

Lubricants are an important part of the pulling process. Pulling lubricant is very important to reduce friction and minimize damage to the cable jacket. Lubricant decreases pulling time to complete the job.

To match cable puller and accessories to job requirements, contractors consider length of the pull, number of bends in the conduit, cable weight, and the amount of force necessary to complete the pull. It is necessary to know these variables to select the correct pulling rope.

There are many tools on the market with many different functions and accessories. RectorSeal® markets a 4,000 lb. capacity lightweight cable puller called StrongArm™. It is incredibly strong, but is easy to set up and use. Designed for one man operation, it sets up and locks into position in 60 seconds. A swivel head easily switches from underground to overhead pulls. The StrongArm™ has two pulling speeds: 80ft./min. or 20ft./min. and is operated with an easy to use foot pedal. It folds for easy handling and storage.

Safety is an important consideration when evaluating pullers.
