MacLean Power Systems is the only provider offering a complete, fire-retardant H-Frame Crossarm solution that simplifies both procurement and installation. The UVMAXX ™ H-Frame Crossarm and its components come in a single, customizable kit—eliminating the complexity of sourcing multiple parts.

Nova Pole manufactures complete single or multi-circuit H-frame transmission structure assemblies, or can provide only the poles, crossarms, or crossbraces as required. Direct-embedded and anchor bolt foundation options are available.

Whether a single pole, multi-pole, H-frame, A-frame, 3-pole or custom structure, Sabre works with clients to design and manufacture specialty structures. All of our poles are manufactured with an emphasis on quality and ease of installation.

Program borrowers with a basis for procuring adequate single pole and H-frame steel transmission line structures. Use of this specification should help eliminate ambiguities that might arise in the evaluation process of competitively bid steel pole procurements. Borrowers or their engineering representatives will need to complete and add to this

We've compiled a list of things to consider when deciding on using direct embedded versus drilled pier foundation for steel transmission poles.

Cost per mile can be related to pole height and class of poles as shown in Figure 2. To keep the cost down, the line design should be based on one tangent structure type and one or two pole classes for the majority of the line. For H-frame structures, the engineer should consider double

– Tip/Base Joint connection method for things like A-Frames or push poles. – Location of pole relative to PLS-POLE origin – Inclination for things like modeling rake.

Grid Structures can supply anything from one light duty steel pole to miles of massive, engineered structures and everything in between. Available finishes are galvanized, weathering steel, and even painted. Additionally, we can provide sub-grade corrosion protection on embedded poles.

PUPI single sided H-frame systems have been extensively tested and shown to exceed RUS strength requirements for TH-10 V4 construction by 21%. 1 Optimized PUPI’s optimized H-Frame designs can reduce assembly weight by over 50% and dramatically increase ease of installation.

Jul 14, 2020 · If you need to assess an existing pole you probably can’t accurately determine if the bracing is effective. A conservative approach is to consider the poles as unbraced. The images above show output from a simple finite element analysis, modelling the poles as beams with a load applied at the tip.
