Slip Ring for Mobile Solutions
Penlink Design Slip Ring For Electrification of Excavators & Rotary Tools
Penlink’s compact slip ring designs for electrifying excavators and mobile equipment offer versatile, high-performance power transmission solutions tailored to meet the unique needs of each customer.
While our example slip ring features a mid-voltage rating of 3x250A (1000V), we have the capability to modify our designs to match specific customer requirements, whether for higher or lower voltage and current specifications. Built with durable SS 304 stainless steel, our slip rings can be adapted to provide varying degrees of environmental protection, from IP54 to IP65, ensuring reliability in harsh conditions.
With a compact form factor for easy integration into space-constrained areas, such as the rotor under an excavator’s seating, Penlink is equipped to deliver the precise solution needed for any electrification project.
- Reliable performance in heavy-duty electrical applications, including mid-voltage transmission for machinery operating in harsh conditions.
- Fits into space-limited areas, such as under-seat rotors, without sacrificing performance.
- SS 304 stainless steel housing ensures the slip ring withstands corrosion and harsh environmental conditions, reducing maintenance and downtime.
- Supports continuous 360° rotation with stable transmission of both power and signals, ensuring smooth excavator operation.
