In the world of electrical infrastructure, the cost of failure can be catastrophic. But sometimes, the most unassuming component plays the biggest role in preventing disaster. SubSaver is built to break. When it does, everything else keeps working.
In May and June of 2025, four SubSaver units sustained direct lightning strikes. While their remains were damaged beyond repair, their performance was a powerful testament to their purpose.
Over one million dollars in replacement costs
Damage to ESP motors, pumps, and cables
Costly downtime and lost production days
Full system pull and reinstallation
Long-term disruptions to operation and productivity
These units did exactly what they were designed to do. They absorbed the surge, took the damage, and protected the valuable infrastructure behind them.
Each SubSaver is engineered with precision to serve as a front-line defense against extreme electrical events.
Six-mode protection filled with pliable epoxy
24 metal oxide varistors (MOVs) encased in approximately half an inch of epoxy
MOVs increase resistance to manage and suppress voltage surges
A typical lightning strike delivers 140 kWh in just 30 microseconds
That amount of energy:
Vaporizes #2 copper strand wire
Melts Dow Corning Sylgard flame-retardant epoxy
Causes visible cracks in the epoxy where the varistor absorbed the impact
Produces extreme heat, released through vent holes on the bottom edge
SubSaver absorbs the shock so your system stays operational.
In all four lightning strike cases, the downhole equipment continued functioning after the SubSaver was replaced. These units took the full force of the surge, and nothing else was damaged. That kind of performance speaks for itself.
SubSaver did its job. Operations stayed on track. No expensive repairs. No downtime.
It is a simple concept with powerful results. Designed to fail so your system does not, SubSaver captures dangerous electrical energy before it can destroy high-value assets. If your business relies on continuous uptime and asset protection, SubSaver is the solution that delivers.
SubSaver stops lightning and keeps you producing.
