Are HVC capacitors suitable for smart grid FTU (Feeder Terminal Unit) applications?

Absolutely — HVC's N4700 dielectric high voltage ceramic capacitors are specifically engineered for smart grid Feeder Terminal Unit (FTU) and Distribution Terminal Unit (DTU) voltage sensing and energy storage applications.

Smart grid FTU/DTU environments present unique challenges that HVC's product portfolio directly addresses:

Smart Grid Requirement

HVC Solution

Technical Rationale

|----------------------|--------------|--------------------|

Long-term reliability under continuous operation	N4700 Class 1 dielectric	Zero aging effect, stable capacitance over 20+ years
Wide ambient temperature range	-55°C ~ +125°C operating range	Covers outdoor cabinet deployments from Arctic to tropical zones
High insulation resistance for precision sensing	≥200,000 MΩ typical	Ensures accurate voltage division ratio in sensor circuits
Low dissipation factor for efficiency	DF ≤0.2% @ 1kHz	Minimizes self-heating in compact enclosure designs
Partial discharge immunity	CIV >50% rated AC voltage	Prevents corona-induced degradation in humid environments

HVC supplies major Chinese State Grid contractors and international smart meter manufacturers with customized FTU-grade capacitors featuring enhanced creepage distances and conformal coating options.
