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.

WIDELY APPLICATIONS
01
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.
02
wind energy
Heavy-duty connectors are vital in wind energy for their robustness and reliability. They withstand harsh conditions like salt spray, humidity, and vibration in both onshore and offshore turbines. With high IP ratings and corrosion-resistant materials, they ensure stable power and signal transmission. Their modular design allows flexible integration in pitch systems and control cabinets, simplifying installation and maintenance. This reduces downtime and enhances overall operational efficiency in wind power applications.
03
Transportation Railway
In rail transit, heavy-duty connectors deliver an "all-in-one connection solution" for critical systems like traction power and signaling. Designed to withstand extreme temperatures (-40℃ to +125℃), they meet IP68 and EN 61373 standards for harsh environments. Integrated smart monitoring and color-coding enable predictive maintenance and minimize downtime.
