Product Introduction
In the fuse protection chain of high-voltage direct current photovoltaic systems, Copper Tube Cap Fitting is not only a structural component, but also a key electrical interface that determines the breaking performance and long-term current stability of the fuse. Our precision copper end caps are designed specifically for photovoltaic fuses (PV Fuses) and high current DC circuit breakers. Through material microstructure control and precision stamping forming processes, they solve the three major engineering pain points of contact resistance drift, thermal cycling fatigue, and electrochemical corrosion in high current density scenarios.
Core adaptation engineering scenario
Photovoltaic power station combiner box protection system
Copper Tube Cap Fitting is suitable for fuse components in centralized and distributed photovoltaic power station combiner boxes. As the core conductive connection component, it ensures the reliability of overcurrent protection during the current convergence process of multiple photovoltaic modules.
01
Front end protection of photovoltaic inverters
Copper End Caps are used to connect fuses on the input side of the inverter, withstand high voltage DC shocks, quickly respond to short-circuit faults, and protect the core components of the inverter (such as IGBT modules) from damage.
02
Photovoltaic cascade protection system
Custom Copper Caps are adapted to photovoltaic module cascade fuses, providing precise protection against single string module failures and avoiding the spread of faults that affect the operation of the entire photovoltaic array.
03
New energy storage supporting protection
Copper End Cap can be expanded to adapt to the fuse components of the energy storage system, meeting the overcurrent protection requirements during the charging and discharging process of the energy storage battery, and ensuring the safe and stable operation of the energy storage system.
