DIFFERENT SIDES
Interlink
As shown in the figure is the side display of our product. From this angle, you can have a more complete view of the structure of our product. The 4-pin through-hole can provide products with and without marks.
machine side
This crimp connection 4-pin insert is connected to the machine and electrical equipment through the wiring side and tightened with a manual hydraulic clamp. It can achieve the current transmission of 40A and a voltage of 830V.
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.
OUR FACTORY & QUIPMENT
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.
warehouse
This image showcases our company's comprehensive warehousing system. To ensure a stable and reliable supply, the vast majority of our products are supported by strategic inventory plans, typically maintaining over 90% availability. This allows us to consistently support your project timelines and operational continuity.
COMMUNICATION EQUIPMENTS
In communication equipment, heavy-duty connectors integrate power and data transmission into a single, robust plug. They provide reliable performance in harsh outdoor conditions, such as extreme temperatures, rain, and vibration. With modular, hot-swappable pins, these connectors enable quick maintenance and part replacement without system shutdown. This ensures uninterrupted operation for critical infrastructure like 5G base stations and data centers, enhancing efficiency and reducing downtime.

MARINE APPLICATIONS
In marine applications, heavy-duty connectors provide critical, high-reliability interconnections for power, signal, and data transmission. They are vital within propulsion systems, power generation, and deck machinery. Engineered to withstand harsh conditions like high current, extreme vibration, and corrosion, their robust sealing (e.g., IP68/IP69K) ensures operational integrity, safety, and efficiency for vessels.
