Substations

Thermal Performance That Doesn’t Derate Under Pressure

• Substations are isolated, operate in dense areas, are sealed, and run hotter, pushing traditional capacitors past their limits. High heat and fast switching cause drift, derating, and frequent failures that raise maintenance costs and threaten reliability.
• NanoPlex LDF films deliver full-rated capacitance up to 135°C with no derating, shrinkage, or performance loss. With self-healing properties, they resist micro-faults and ensure long-term stability in the harshest substation environments.
• With NanoPlex capacitor films, utilities can build smaller, cooler, and more reliable capacitor banks without active cooling. The result is greater reliability, lower operating costs, and substations ready to handle rising demand and thermal pressure. 

Scale Performance Where Space is Limited

• Distribution substation and underground substations operate in dense areas. Traditional capacitors can’t scale performance in these environments, requiring more units to meet demand, which drives up cost, complexity, and installation time.
• NanoPlex HDC films scale where traditional designs stop, delivering up to 4x more energy density in the same footprint. This enables higher performance without adding size, weight, or extra components.
• Engineers can gain more power and advanced filtering in the same space, streamlining installation and cutting infrastructure costs. The result is a reliable, high-density solution that keeps substations efficient under space constraints.

• Substations face rising harmonic distortion from inverter-based renewables, storage systems, and industrial loads. These harmonics create electrical noise that overheats equipment, degrades power quality, and threatens the reliability of sensitive downstream electronics. Traditional capacitors struggle to filter these high-frequency distortions.
• NanoPlex capacitor films are engineered with ultra-low impedance and high-frequency response, allowing them to suppress harmonics across a wide spectrum. By keeping total harmonic distortion (THD) below 5%, they stabilize voltage, reduce noise, and improve power factor in hybrid power correction systems.
• Utilities and OEMs can deliver high electrical quality, cleaner, more reliable power from substations, protect critical infrastructure, and extend equipment life. With controlled harmonics, substations operate more efficiently, reduce maintenance costs, and maintain compliance with increasingly strict power quality standards.

• Long HVDC cable runs and shifting loads introduce voltage ripple that traditional capacitors struggle to smooth out. This instability weakens grid performance, increases heating losses, and puts sensitive equipment at risk across renewable and cross-border networks.
• NanoPlex capacitor films feature ultra-low ESR (Equivalent Series Resistance), meaning they waste less energy in heat, run cooler, and respond faster to high-frequency switching. With rapid frequency response, they reduce voltage ripple, maintaining efficiency under heavy ripple and load swings.
• Utilities and operators can maintain tighter voltage control over long distances, protect critical equipment, and deliver higher power quality. The result is more reliable HVDC transmission, better integration of renewable energy, and reduced maintenance costs.

Withstanding the Elements Surrounding Substations

• NanoPlex LDF capacitor films are hermetically sealed and chemically resistant, preventing moisture ingress and corrosion. Their design ensures stable operation even in the harshest substation environments.
• Capacitor banks remain in service up to 5x longer with fewer failures, reducing maintenance cycles, minimizing downtime, and lowering replacement costs. Utilities gain more reliable, lower-maintenance substations that remain resilient in demanding deployments.

Secure Substations with a Stable Domestic Supply

• NanoPlex capacitor films are engineered and manufactured in the U.S., using materials sourced exclusively from allied nations. A domestic supply provides a secure and resilient supply chain.
• Over 70% of capacitor film is imported, leaving utilities and OEMs exposed to geopolitical risk, long lead times, and unpredictable costs. Traditional capacitors built on these imports create uncertainty for critical substation projects.
• Manufacturers and utilities can have confidence in a reliable, North American supply of capacitor film that meets Buy American standards, cuts delivery risk, and supports cost control for long-term grid modernization.
