Application Cases

MingYang Smart Energy, one of the world's largest offshore wind turbine manufacturers, required highly reliable communication slip rings for their offshore wind turbine series operating in harsh marine environments.

Hanwell provided custom contactless fiber optic slip rings (FORJ) designed specifically for offshore conditions, with enhanced corrosion resistance and IP65+ protection.

Hanwell supplies approximately 70% of MingYang's communication slip rings. Products have demonstrated stable performance in high-salinity, high-humidity offshore environments with minimal maintenance requirements.

Wind farms across diverse climates and terrains require slip rings that can withstand extreme temperatures, dust, vibration, and long-term continuous operation.

Hanwell's contact-type and contactless slip rings have been deployed across 36,000+ megawatt-class wind turbines, covering major wind farm projects in northern, northwestern, and coastal regions of China.

Proven reliability across diverse operating conditions including extreme cold (-40°C), high temperature (+50°C), sandy environments, and high-altitude installations.

Aging wind turbines face increasing slip ring failures, rising maintenance costs, and difficulty sourcing replacement parts for discontinued models.

Hanwell's upgrading service provides comprehensive assessment, custom-designed replacement slip rings (often upgrading from contact-type to contactless), professional installation, and commissioning.

Extended turbine service life by 5-10 years, reduced maintenance frequency by over 70%, and eliminated unplanned downtime caused by slip ring failures.
