PROFESSIONAL TEST
HAOKE has advanced devices for heavy-duty connectors' production and test. These devices covered the whole life cycle from material performance to electrical safety, mechanical strength, and environmental adaptability, building a scientific defense line for product quality.
CORE ACCESSORIES
CCSM & CCSF
Our 40A rated male and female pins are precision-engineered through automated die-casting. With a durable 3μm silver plating, they guarantee low contact resistance, stable current delivery, and impeccable signal integrity for demanding communications applications.
Complementary components
On this 3-pin side, the male and female inserts interconnect via mating inserts, ensuring stable power and signal integrity by reliably transmitting both current and voltage. Designed for high-power applications, the manual hydraulic clamp connected insert , secured with the separared crimp pins, and rated up to 40A and 500V.
HF24B-NLA
The HF24B series frame is the one in this series that can accommodate the largest number of cores, capable of simultaneously accommodating six single-pin modules and suitable for all 24B hoods&housings.
in Solar Systems
In solar systems, heavy-duty connectors are vital for linking photovoltaic modules to combiner boxes. They ensure stable power transmission under harsh outdoor conditions, featuring high weather resistance and IP65+ protection. This guarantees reliable connectivity and enhances the overall efficiency of solar installations.
In Wind Energy
Heavy duty connectors, like HAOKE's modular HM series, provide compact, reliable solutions for wind turbine systems. Integrating power and signal transmission in pitch controls and nacelle cabinets, they enable flexible configurations, reduce installation time by 50%, and simplify maintenance-ensuring stable operation even in harsh gust-prone environments.

DC Temperature Rise Test
This test monitors conductor temperature under load to determine safe current capacity. As current increases, resistive heating causes temperature rise, reducing ampacity. The evaluation considers conductor size, ambient conditions, and thermal properties to establish safe operating limits and prevent overheating in electrical systems.
