Heavy-duty slip rings for port crane equipment（14*400A+5*100A）

Features

Robust Enclosure Structure

The enclosure is constructed from SPCC steel plate with a yellow industrial paint finish, providing excellent mechanical strength and basic corrosion resistance while enhancing equipment visibility and safety.
Wide Temperature Operating Capability

Operating temperature range of -40°C to +40°C, ensuring stable performance in low-temperature and harsh climatic conditions. Suitable for outdoor and port equipment applications.
High-Reliability Contact System

Utilizes a proprietary copper-graphite + precious metal composite contact material, balancing high current-carrying capacity with stable signal transmission. This effectively reduces wear and extends service life.
Protection Rating Design

When installed vertically with the stator facing upward, the protection rating achieves IP56, offering excellent dust resistance and protection against powerful water jets. This makes it suitable for harsh industrial environments.
