System fit
Check the installation point
Confirm the voltage class, feeder arrangement, equipment interface and switching duty at the actual site.
Application and product scope
Renewable Energy & Storage
Protection, isolation and insulation components for solar, wind and storage collection networks in exposed environments.
Solution at a glance
Start with the network conditions
The right product depends on voltage, fault duty, installation environment and the way maintenance crews will isolate the circuit. These details are confirmed before a model is quoted.
Risk control
Match protection to the duty
Use the available fault current, overvoltage exposure and insulation level to set the protection and arrester requirements.
Project output
Issue a usable product schedule
Turn drawings, standards and site conditions into model numbers, quantities and documents that purchasing can use.
Application Scope
Solar, wind and energy-storage projects connect generation assets to collection feeders, step-up transformers and the utility grid. GRL supports these outdoor interfaces with protection, isolation and insulation components selected for remote sites and repeated thermal, ultraviolet and weather exposure.
Operating Considerations
- Step-up transformers and collection feeders need coordinated protection against faults and surges.
- Remote sites require field-replaceable components and clear isolation for service planning.
- Pollution, wind, salt, altitude, ultraviolet exposure and access conditions influence insulation and fitting selection.
GRL Product Scope
- Drop-out fuse cutouts and fuse links for step-up transformer and collection-feeder protection.
- Surge arresters for lightning-prone outdoor networks and grid-connection points.
- Disconnect switches, composite insulators and fittings for safe isolation and stable installation.
Project Inputs
Share the generation and collection voltage, transformer rating, grounding method, fault level, site altitude, pollution or salt exposure, mounting details and expected quantity. GRL can support a project-specific product schedule.
Expected Outcomes
- Protection packages suited to remote and weather-exposed sites.
- Improved resilience against outdoor overvoltage and insulation stress.
- Clear documentation and repeatable supply for project construction and maintenance.
