Complying with Code: Using the Strand Tensionmeter

The Strand Tensionmeter (70046), also known as the Strand Dynamometer, is a powerful tool used to measure the tension of existing strand between telephone poles. The tool is furnished with an analog thermometer, temperature compensation charts, detailed instructions for use, and a hard shell plastic carrying case cushioned with foam rubber for protection.

The Strand Tensionmeter is a precision instrument which can quickly measure tensions of 1/4 inches (6.6M), 5/16 in. (6M), 3/8 in. (10M), or 7/16 in. (16m) strand. It can be used on strands with up to 10,000 lbs of tension. One of the main features is that it’s a completely mechanical system — so you don’t have to worry about replacing dead batteries.

The Strand Tensionmeter helps assure that you are always in complicance with the National Electric Safety Code’s Uniform System of Clearances even considering the temperatures affecting the strand on hot or cold days. Wes Wolfert of Wolfert Consulting, LLC, (Former Bell/Verizon Construction Staff) states “It is considered essential for Communication System Owners to meet the recognized industry standards (Section 4.4 of Telcordia SR – 1421) by maintaining steel strand support members that support load and clearance with the same regard given to pole class design section per ANSI 05.1. In order to meet the tension standards, tensioning is only verified with the use of an approved tensioning tool such as the GMP Strand Tensionmeter (70046).”

The Strand Tensionmeter needs to be recalibrated on a regular basis, which we handle here at the factory. So contact our customer service team for information on our calibration services.

The Cable Pusher: Pushing Through the Trenches

89760 cable pusher

The sturdy Cable Pusher (89760) is ideal for installing electrical cables in trenches or underground work. The Cable Pusher provides often needed mid-assisting support between the Cable Reel and the Winch. It is hydraulically driven and typically powered by a Power Pack (supplied separately) with an output of 4

gallons/minute and 1500 psi (max). The Power Pack (32799) features an integrated oil cooler, which is particularly important when working for long periods of time or in high temperature environments. The direction and speed of the Cable Pusher is controlled by a Control Valve with Hoses (89761) featuring a spring-centered valve.

Best in its Class: The Cable Pony Winch

The GMP Cable Pony is a hydraulic winch that often is regarded as the best winch produced by GMP. This universal winch is ideally suited to ADSS installations, but can be used in general aerial stringing work, conductor recovery and underground cable handling as well. In our ADSS installation blog, we discussed the use of the cable pony in ADSS installation. When installing ADSS cable, your team needs a winch that they can trust will provide optimal service throughout the job. Today, we’re taking a closer look at why the cable pony is one of the best winches on the market. Continue reading Best in its Class: The Cable Pony Winch

Microduct Overriding: Part 3

Microduct overriding has become an increasingly popular method to install new cable in an overly saturated area that may not allow for new ducts to be installed. While the process is not new, it’s incredibly important that your team uses the best possible equipment to get the job done right, avoiding any hiccups that could occur during installation.

Sheaves, Shackles, and Jamb Skids: Equipment Needed for Underground Cable Installation

When pulling cable underground, an assortment of highly specific tools are needed in order to properly and efficiently feed cable into an existing duct. Below the manhole, a combination of sheaves, shackles, and jam skids are needed to effectively get the job done. In this blog, we’ll be explaining the necessary tools for underground cable placement, and providing a few examples of how they fit together.
