Power connector arcing prevention in high-voltage switchgear represents a critical challenge that JVT CONNECTORS Factory has been solving since 2002. Our specialized manufacturing capabilities address the most demanding electrical safety requirements through innovative connector designs that eliminate dangerous arcing events in utility, industrial, and infrastructure applications.
Understanding the Arcing Prevention Challenge
Electrical arcing in high-voltage switchgear occurs when current jumps across air gaps between conductors, creating plasma channels exceeding 20,000°C. This phenomenon poses severe risks including equipment damage, fire hazards, and personnel injury. Our engineering team has identified the primary factors contributing to arcing failures and developed targeted solutions to address each challenge.
Root Causes of Switchgear Arcing
- Contact Surface Contamination: Dust, moisture, and chemical deposits create conductive paths that reduce breakdown voltage and initiate arcing events
- Mechanical Wear: Repeated connection cycles create rough surfaces with stress concentrations that promote arc formation
- Thermal Cycling: Expansion and contraction cycles loosen connections, increasing resistance and generating destructive heat
- Environmental Degradation: Humidity, salt spray, and chemical exposure accelerate connector deterioration and reduce arcing prevention capabilities
