With wildfire threats increasing in frequency and intensity, utility providers are rethinking grid design as a frontline strategy for risk mitigation. In high-risk zones, the focus has shifted from reactive measures to proactive system upgrades—prioritizing components and configurations that directly reduce ignition potential while maintaining grid reliability.
Utilities leading the charge are adopting technologies engineered specifically to address common wildfire ignition sources, such as vegetation contact, conductor clashing, and equipment failure. Among the most effective strategies: covered conductor systems, fire-retardant insulators, and spacer cable configurations that enable tighter phase spacing and enhanced mechanical resilience.
Key Considerations for Utility Wildfire Mitigation:
- Covered Conductors: Designed to prevent arcing and faulting during contact with vegetation or other conductors—critical in areas prone to wind events and heavy foliage. Marmon Utility’s Hendrix™ Covered Conductor System, for example, is helping utilities reduce wildfire risk without the high cost of undergrounding.
- Fire-Retardant Components: Insulators that meet UL 94 V-0 standards offer self-extinguishing properties, helping contain potential ignition events before they spread. Marmon Utility offers a full portfolio of flame-resistant insulators and hardware tested to meet utility-grade reliability under fire conditions.
- System-Level Benefits: Spacer Cable systems reduce sag, increase ampacity, and allow for narrowed right-of-way clearances—preserving vegetation while minimizing the need for extensive tree removal. Over a 50-mile span, that can mean protecting more than 48,000 trees.
- Regulatory Readiness: With wildfire mitigation plans under increasing scrutiny from public utility commissions, these solutions support compliance and long-term grid hardening efforts. Marmon Utility partners with utilities early in the planning phase, offering design support and materials tailored to regulatory frameworks and terrain challenges.
For utilities aiming to balance safety, cost-efficiency, and environmental stewardship, the right parts and system-level engineering choices can make a measurable difference. As wildfire risk becomes a year-round concern, the conversation is no longer if utilities should act—but how quickly they can implement smarter solutions.
