Every Hi-Tech ERS configuration is engineered to perform across the complete transmission voltage spectrum—from 33kV distribution networks to 800kV HVDC corridors. Designed for diverse transmission applications, each configuration supports reliable restoration, planned maintenance, temporary bypass, and reconductoring projects while maintaining proven structural performance and engineering reliability.
Key engineering factors that determine the optimal ERS configuration for each transmission project.
Alignment and route angles determine the ideal ERS configuration for each corridor.
Terrain and crossing conditions influence span design and configuration selection.
Conductor loads determine the most suitable structural ERS configuration design.
Longer spans require stronger configurations to control conductor tension and sag.
Circuit requirements define the appropriate ERS configuration for each application.
Wind, ice, and thermal loads influence structural design and configuration choice.
Ground strength and soil conditions determine foundation and tower selection needs.
Site access limitations influence deployment strategy and configuration selection.

Everything you need to know about HiTech ERS solutions, capabilities, and standards.
Hi-Tech ERS towers are available in five configurations: Suspension (for straight routes), Running Angle (for directional changes), Dead-End/Tension (for high-load termination and crossings), Herringbone (twin-mast multi-circuit), and Chainette (portal-style wide corridor). Each is engineered for a specific functional role within a transmission corridor.
A Suspension configuration supports conductors on straight or near-straight transmission sections where conductor loads are balanced transversely. It is the most common ERS configuration used for emergency bypass lines, reconductoring corridors, and temporary restoration routes along straight alignments.
A Running Angle configuration is used where the transmission line changes direction — at deviation angles typically between 2° and 30°. The cross arm and structure are designed to handle the resultant horizontal conductor load created by the change in line direction, making it suitable for route diversions and corridor adjustments.
A Dead-End or Tension configuration is required wherever the full longitudinal conductor tension must be transferred to the structure — at line terminations, river crossings, long spans, section boundaries, and critical restoration anchor points. These structures are significantly more robust than suspension types and are typically guyed for additional stability.
The Herringbone is a twin-mast ERS arrangement where two vertical masts are connected by cross-bracing in a herringbone pattern. This configuration provides significantly increased structural capacity, making it suitable for multi-circuit systems, heavy-duty restoration projects, and complex loading conditions that exceed the capacity of single-mast configurations.
The Chainette is a portal-style ERS structure designed for wider transmission corridors and special crossing requirements. Its wide base and horizontal top beam allow it to span greater widths than conventional mast configurations, making it the configuration of choice for portal structure replacements and wide corridor crossings.
Yes — in fact, most ERS restoration routes use multiple configurations. A typical route will use Dead-End configurations at each terminal, Suspension configurations across straight sections, and Running Angle configurations wherever the route changes direction. Configuration selection is performed section-by-section based on the engineering requirements at each location.
Configuration selection follows a structured engineering evaluation covering route geometry, tower function, conductor loading, span length, circuit arrangement, voltage level, weather loads, foundation conditions, and access constraints. Hi-Tech's engineering team performs this evaluation for each project to ensure the deployed configuration matches the specific requirements of the transmission corridor.
River crossings require Dead-End/Tension configurations on both banks of the crossing. The dead-end structures anchor the long span conductors across the water body, absorbing the full longitudinal tension generated by the extended span. Suspension towers on either side of the dead-ends carry the normal balanced loads on the approach sections.
Yes. All five Hi-Tech ERS configurations — Suspension, Running Angle, Dead-End/Tension, Herringbone, and Chainette — are available for deployment on systems from 33kV through to 800kV, including 400kV EHV and 765kV UHV corridors. Configuration dimensions, structural capacities, and insulator string arrangements are engineered to suit the specific voltage class requirements.
