Frequently Asked Questions

We provide comprehensive interconnect solutions for the entire renewable energy ecosystem, including Utility-Scale Solar (PV) arrays, Wind Turbine nacelles, Battery Energy Storage Systems (BESS), and EV charging infrastructure.

Renewable energy installations face extreme elements. We engineer our harnesses using specialized materials like XLPE and UV-resistant TPE, ensuring robust protection against UV radiation, ozone, hydrolysis, and extreme temperature fluctuations (-40°C to +125°C), backed by IP67/IP68 sealing.

Yes, high-power transmission is our specialty. We process heavy-gauge cables and utilize advanced terminations (including ultrasonic welding and custom heavy-duty lugs) to ensure safe, low-resistance connections for 1500V DC energy storage systems.
