Brass Terminal Block: Fully Powered, Worry Free Connection
At the critical stage of power transmission and equipment connection, brass terminal blocks, with their excellent conductivity, stability, and durability, have become the "invisible guardians" to ensure the safe and efficient operation of circuits, truly achieving "full power, worry free connection".
1、 Material advantage: Brass creates a reliable foundation
Brass (copper zinc alloy) has a copper content of 60% -70% as its core, combining the high conductivity of copper with the strengthening properties of zinc. Its conductivity reaches 97% IACS (International Annealed Copper Standard), only slightly lower than pure copper, but its hardness (HB140-180) is significantly improved through zinc alloying, and its deformation resistance is 1.5 times that of pure copper. This "combination of rigidity and flexibility" characteristic enables brass terminals to efficiently transmit current while withstanding the mechanical stress of repeated insertion and removal, avoiding heating or circuit breakage caused by looseness.
2、 Performance Breakthrough: Three Core Advantages
Corrosion resistance and aging resistance
The naturally formed oxide film on the surface of brass can block moisture and chemical erosion. In coastal or high humidity environments, its service life is extended by more than three times compared to aluminum terminals, reducing the risk of poor contact caused by corrosion.
Precision crimping technology
Adopting a hexagonal crimping cavity design, the wire and terminal form an airtight connection through mechanical pressure, with a contact resistance as low as 0.5m Ω or less, which is 80% lower than traditional winding connections and effectively reduces electrical energy loss.
Wide temperature adaptability
It can work stably within the range of -40 ℃ to 150 ℃, and even in the face of extreme temperature differences or overload currents, it can maintain structural integrity and avoid connection failure caused by thermal expansion and contraction.
3、 Application scenario: Full domain coverage
From socket wiring for household circuits to motor connections for industrial equipment; From high-voltage battery packs for new energy vehicles to inverter interfaces for photovoltaic power generation, brass terminals have become the preferred choice across industries due to their versatility. For example, in the installation of smart meters, brass terminals can ensure the stability of data transmission with an error rate of less than 0.1%.
4、 Security Certification: Global Standard Endorsement
The product has passed international certifications such as UL (United States), CE (European Union), CCC (China), etc. It has undergone salt spray testing for 96 hours without rust, and its flame retardant rating meets V-0 standards, providing comprehensive safety protection for power connections.
Brass terminal blocks carry the "big responsibility" with "small parts", and use reliable materials and exquisite craftsmanship to ensure the transmission of every kilowatt hour of electricity.
