What are Pulling Irons?
Pulling irons are specialized tools designed to assist in the installation of electrical and telecommunications cables. They are used to grip and pull cables through conduits, manholes, and ducts, ensuring that the cables are safely and securely installed. The design of pulling irons allows for a firm grip on cables, minimizing the risk of damage during the installation process.
Types of Pulling Irons
Pulling Iron (Hytrel)
Hytrel pulling irons are made from a flexible material that is ideal for lightweight and delicate cables. Their flexibility allows for easy maneuverability in tight spaces, making them suitable for telecommunications applications where cables must be pulled through intricate paths.
Pulling Iron (Polypropylene)
Polypropylene pulling irons are known for their durability and resistance to various environmental factors. They are perfect for fiber optic cables, providing a secure grip without applying excessive force, which could damage sensitive cables.
Pulling Iron (Steel)
Steel pulling irons are designed for heavy-duty applications. Their robust construction makes them ideal for pulling larger electrical cables in industrial settings. They are built to withstand significant stress and strain during the installation process.
Pulling-In Iron
Pulling-in irons are specifically designed for underground vaults where cables need to be pulled to a dead-end. They are typically shorter and more robust to handle the unique demands of underground installations.
Strand Pulling Iron
Strand pulling irons are used primarily for overhead cable installations. These tools are designed to handle the weight of multiple cables strung along poles, ensuring that the installation process remains efficient and safe.
Selecting the Right Pulling Iron
When it comes to selecting the right pulling iron, consider the following factors:
-
Type of Cable: Different cables require different pulling irons. For example, lightweight fiber optic cables may need a Hytrel pulling iron, while heavy-duty electrical cables would need a steel option.
-
Length: The length of the pulling iron can impact its effectiveness. Longer irons can reach deeper into conduits, whereas shorter ones are easier to handle in tight spaces.
-
Material: The material of the pulling iron affects its durability and flexibility. Choose a material that suits the specific needs of your application.
-
Application Environment: Consider the environment where the pulling iron will be used. For outdoor or harsh conditions, materials that resist weathering and corrosion are ideal.
-
Manufacturer Reliability: Opt for pulling irons from reputable manufacturers like those found on www.inwesco.com, www.hubbell.com, or meadowburke.com. These brands ensure high-quality products that meet industry standards.
