Slip ring for marine applications

industrialbrassPTFE

Short Description
This high-current slip ring features a 130mm outer diameter, IP65-rated protection, and four independent 200A power channels, purpose-built for heavy-duty construction machinery. It provides reliable continuous power transmission in harsh outdoor conditions, with strong vibration and shock resistance and extended service life for excavators, cranes and other rotating equipment.

Product Description
Our 130mm OD high-current slip ring from Ingiant is a rotary electrical connector engineered for the demands of construction and heavy industry. With four dedicated 200A power channels and IP65 dust/waterproof sealing, it maintains uninterrupted power transfer between stationary and rotating components in excavators, mobile cranes, aerial work platforms and rotary drilling rigs. Designed to resist vibration, shock and extreme weather, the unit minimizes downtime and maintenance in tough jobsite environments.

Core Design & Performance Features

• 4×200A high-current power channels — four fully independent 200A channels support high-power three-phase transmission plus auxiliary circuits; parallel-stranded copper conductors reduce resistance and heat for stable continuous operation.
• IP65 harsh-environment protection — sealed housing prevents dust and water ingress, suitable for outdoor construction sites with rain, mud and vibration; reduces internal contamination and maintenance needs.
• 130mm compact robust structure — 130mm outer diameter balances compact installation with high current capacity, ideal for turrets and rotating joints with limited space; reinforced metal housing for shock and vibration resistance.
• Premium materials & reliability — precious metal alloy contacts for low contact resistance and long wear life; PTFE insulation for high temperature (-40°C to +120°C) and chemical resistance; tin-plated copper conductors for conductivity and corrosion resistance; color-coded wires for simplified installation.

Application Scenarios

• Construction machines: excavators, mobile cranes, aerial work platforms, concrete pumps, rotary drilling rigs
• Heavy industrial equipment: port cranes, mining machinery, tunnel boring machines
• Offshore & marine: offshore cranes, shipboard rotating systems
• Other heavy-duty rotating systems: wind turbine pitch systems, industrial rotating tables
