JINPAT Hollow Shaft Slip Rings for Cable Reels in High-Temperature Environments

Current cable reel operating environments face unique challenges: extreme temperatures, fluctuating humidity, and dusty conditions. From towering construction sites in Dubai to massive energy facilities in Abu Dhabi, equipment must operate reliably with uncompromising performance.

JINPAT  dedicated hollow shaft slip rings address these challenges head-on. Their compact design saves valuable space in mobile machinery while providing superior functionality—including an integrated high-frequency channel for critical data transmission. The corrosion-resistant aluminum alloy housing undergoes sandblasting and oxidation treatment, effectively resisting the corrosive effects of dusty environments.

Please refer to the following technical specifications:

• Operating temperature range: -40℃ to +80℃

• Humidity tolerance: Below 88% RH

• Insulation resistance: 1000MΩ for power circuit at 500VDC

• Contact resistance fluctuation: ≤70mΩ at 50rpm

• Speed range: 0~250rpm

Gold-to-gold contacts ensure signal integrity even under harsh conditions. IP51 protection provides necessary dust protection, while precise cable lengths (rotor: 650±10mm, stator: 300±5mm) enable seamless integration into the device.

The conductors are made of precious metals, and the signal circuits feature an all-gold-to-gold design, ensuring reliable data transmission even under varying humidity and temperature conditions. The conductor specifications are AWG16#/AWG20#, with current-carrying capacity meeting stringent industrial requirements.

This hollow shaft slip ring provides uninterrupted power and clear signal transmission when needed. We can also provide customized solutions.
