As China's leading circuit breaker wire manufacturer, HAIPART designs wires that serve as the "current blood vessels" in trip protection systems - connecting external circuits to internal components. From power input terminals to signal transmission between contacts and coils, our wires ensure stable current conduction that directly impacts breaker response time and safety performance.
Specializing in "Material Excellence + Process Optimization", we provide customized wire solutions for various breaker types and application scenarios.
