Success Stories & Case Studies
Large Middle Eastern PV Energy Developer
Connector damage rate dropped from 8% annually for original imported products to below 1.2%, downtime caused by connection failures reduced by 70%, and cumulative savings in maintenance and generation losses exceeded 80,000 USD.
Customized for the extreme desert environment of the Middle East, the housings passed 1,000-hour UV aging tests, and seals use high-temperature fluororubber, maintaining stable sealing under 70°C surface heat and strong wind-sand erosion. Combined with silver-plated terminals to keep contact resistance at extremely low levels, this effectively ensured the long-term generation efficiency and revenue of desert power plants.
Coastal Open-Air EV Charging Station Project in Europe
Connector-related electrical failure rate plummeted from 18% annually to 2.6%, annual maintenance cost per station dropped from over 500 RMB to below 80 RMB, and new station installation efficiency increased by 35%.
Tailored for Europe’s coastal high-salt fog, strong sea wind, and high-frequency vibration conditions, the connectors use 304 stainless steel and a dual-seal anti-loosening structure, passing 1,000-hour salt spray tests and IEC 60068-2-6 vibration tests. This completely solved the industry pain point of traditional IP67 connectors failing due to water ingress within 6 months, becoming the designated standard for the operator’s European coastal stations.
