650A High Current Liquid Slip Ring with 316L Stainless Steel Housing
This 650A high-current liquid slip ring is engineered for ultra-large-scale current transmission applications. Featuring a 316L medical-grade stainless steel housing and silver-plated copper conductive pillars, it delivers extremely low resistivity and superior corrosion resistance. The single-channel design supports 500A standard current capacity with 650A peak capacity, operating at up to 400V and maximum speeds of 200rpm. Ideal for heavy industrial applications requiring continuous rotational transmission of ultra-high current, including electroplating, electrolysis, high-power welding, and rotary testing benches.
Key Features
500A-650A High Current Capacity: Single channel supports 500A continuous current with 650A peak capacity for ultra-high power equipment
316L Stainless Steel Grade Housing: Exceptional corrosion resistance against harsh industrial environments including electroplating solutions, salt spray, and acid/alkali gases
Silver-Plated Copper Conductive Pillars: Significantly reduced contact resistance minimizes heat generation and maximizes power transmission efficiency
High-Speed High-Current Compatibility: Stable performance carrying hundreds of amperes at 200rpm for dynamic high-power operations

Frequently Asked Questions
Q1: What is the temperature rise of the slip ring under a 500A current? Does it require additional cooling?
Under rated 500A conditions at 25℃ ambient temperature and 200rpm speed, the surface temperature rise is typically controlled within 40K (surface temperature ≤65℃). Forced cooling is generally not required, but installation in well-ventilated locations is recommended. For extended operation near 650A peak current, contact us to assess heat dissipation solutions.
Q2: What are the advantages of 316L stainless steel compared to ordinary carbon steel or aluminum alloy?
316L contains molybdenum, providing superior resistance to pitting corrosion and chloride ion corrosion compared to 304 stainless steel. Its non-magnetic properties prevent eddy current heating under high current, making it ideal for highly corrosive environments such as electroplating and chemical processing.
Q3: Does the product support multi-channel or higher current customization?
Yes, we provide 2-channel, 3-channel, and multi-channel high-current slip rings with single-channel currents expandable to 1000A or higher. Please provide your specific parameters (current, voltage, number of channels, speed, environment) for customized solutions.
