Precision manufacturing, reliable performance of terminal blocks
As the core hub of electrical connections, the quality of terminal blocks directly determines the stability and safety of the circuit system. Relying on a full process precision manufacturing system and strict quality control standards, the terminal blocks we create have become the preferred components in high-end fields such as industrial automation, new energy, and rail transportation with micrometer level accuracy and all-weather reliability.
Precision manufacturing runs through the entire production chain, building a solid foundation of quality from the source. Using high-purity T2 electrolytic copper as the substrate, with a conductivity of 98% IACS, it significantly reduces the risk of resistance and temperature rise compared to recycled copper. Combined with nickel plating, silver plating or tin plating surface treatment processes, it has wear resistance, oxidation resistance and low contact resistance characteristics. Through high-precision CNC machining, high-speed continuous stamping, and precision injection molding technology, the thread accuracy reaches 6H level or above. The insulation base is made of UL94 V-0 flame-retardant plastic to ensure consistency between electrical clearance and dimensional tolerances.
Multiple rigorous tests endow the product with excellent reliability and comprehensive adaptability to complex working conditions. In terms of electrical performance, contact resistance, power frequency withstand voltage, and temperature rise tests are conducted to ensure that the temperature rise does not exceed the standard limit and the insulation resistance remains stable and meets the standard; The mechanical performance has been tested through torque, pulling, and 500 cycles of insertion and extraction life. The screws are tightened without slipping, and the wires are firmly clamped without falling off. At the same time, it has undergone salt spray, high and low temperature alternating, and vibration tests, and can still operate stably in humid, corrosive, and strong vibration environments, complying with international and domestic standards such as IEC 60947-7 and GB/T 14048.7.
From signal distribution in industrial control cabinets to power transmission in photovoltaic inverters, from strong electrical connections in rail transit to precise wiring in medical devices, our terminal blocks are designed with structural optimization to adapt to diverse scenarios. With batch stability guaranteed by the ISO9001/IATF16949 certification system, we provide safe, efficient, and long-term maintenance free connection solutions for circuit systems in various industries.
