From initial requirement through to post-project return or extension, the ERS rental process is designed to remove complexity and accelerate access to deployment-ready systems.
Project type, duration, and configuration needs evaluated
Appropriate ERS configurations identified for the project
Required inventory reserved and confirmed for your project
Customer facility or ERS warehouse — your choice
Inventory dispatched with deployment support coordination
ERS systems installed and transmission restored
Return at project completion or extend rental duration
Hi-Tech offers two flexible inventory storage options — designed around what works best for your utility's operational readiness strategy and project requirements.
ERS inventory can be reserved and positioned at your warehouse or facility to ensure immediate availability whenever deployment is required — eliminating mobilization delays in time-critical scenarios.
Fastest possible deployment access — zero transit lead time from storage to site
Utility-controlled inventory visibility and readiness confirmation
Maximum emergency preparedness — inventory already on your premises
Minimized mobilization time for both planned and emergency deployments
ERS inventory can remain reserved and securely stored within Hi-Tech facilities until deployment is requested — providing access to ready inventory without any storage management responsibility on your end.
No warehouse space, facilities, or storage management required
Reduced inventory management and maintenance responsibilities
Secure, professionally maintained inventory holding at Hi-Tech facilities
Reserved and available for dispatch when your project requires deployment
Hi-Tech ERS rental solutions serve the full range of temporary transmission scenarios — from emergency response to long-horizon planned projects.
Rapid access to reserved ERS inventory following unexpected outages, tower failures, or transmission corridor damage — minimizing time to restoration.
Temporary transmission support deployed rapidly following cyclone, flood, or severe weather events affecting grid infrastructure and requiring bypass solutions.
Rental bypass structures for scheduled maintenance activities — ensuring transmission continuity during planned infrastructure work without permanent ownership.
Temporary ERS support during conductor replacement programmes — rental duration matched to the project timeline without long-term ownership commitment.
Network support structures during planned infrastructure improvement programmes — temporary access for the duration of the upgrade project.
Alternative transmission routing during project execution — rental ERS systems providing bypass capacity exactly when and for as long as required.
Rental and ownership each serve different operational strategies. Understanding where each model adds most value helps utilities make the right decision for their requirements.
Rapid access to deployment-ready inventory helps utilities and contractors respond effectively to both planned and unexpected transmission challenges.
Reserved ERS inventory confirmed and held — at your facility or Hi-Tech warehouse — ready for rapid access.

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.
