This innovative solution supports main cables from 4-16mm² and branch cables from 1.5-10mm² at rated voltage 0.6/1kV. The advanced design eliminates the need to cut main cables, saving 2-3 meters of cable per connection while reducing labor costs and installation time. With flame-retardant, fire-resistant, and waterproof capabilities, our junction box complies with GB/T 14048.7-2016 international safety standards, offering exceptional cost performance for tunnel lighting applications.
What Makes Our Tunnel Lighting Junction Box Different?
Tunnel lighting systems require dependable, long-lasting electrical connections that can resist the extreme conditions underneath. Traditional junction boxes need main wires to be severed, reducing current capacity and increasing failure risk.
And this is where the OUKAMU solution really changes the game. Our proprietary method permits on-site, flexible installation with no pre-measuring or custom work needed. During building you can move branch positions around as much as you want. This makes installation quicker and more flexible to actual situation in the field.
Integrated sealing design for IP68 level protection, ideal for cable wells, direct burial & other tough tunnel situations. This inhibits the intrusion of moisture and electrical leakage for long term steady functioning in underground use.

Installation Steps
Wide Application Scenarios
Our Tunnel Lighting Junction Box serves diverse low-voltage distribution projects across multiple sectors.
Infrastructure Projects
Junction boxes for tunnel construction, metro systems and underground corridors have to endure wetness and limited access for maintenance. Our approach has been successfully used in projects such as Nantong Metro Line 2 and the Hong Kong-Zhuhai-Macao Bridge.
Commercial & Industrial Buildings
Our branch joints give you the ability to flexibly distribute power from industrial floors to commercial complexes without interfering with existing cable systems. Space saving design allows for more efficient routing of wires in packed cable trays and conduits.
Renovation and Improvement Projects
Older installations are often in need of better insulation and waterproofing. Thanks to our integrated junction boxes, upgrades are inexpensive and efficient, as they can be installed in existing systems without substantial cable replacement.
Technical Advantages for Underground Applications
Uncut Main Cable Design
Your main cable stays intact throughout installation. This preserves the original current-carrying capacity and mechanical strength of your electrical system. Fewer connection points mean reduced failure risks and extended cable service life.
Advanced Resin Encapsulation
We use two-part polyurethane resin for complete electrical insulation and mechanical protection. This material provides excellent adhesion to PVC, XLPE, and polymeric cables, creating a waterproof barrier that meets the demanding requirements of tunnel construction.
Flame Retardant and Fire Resistant
Safety is critical in tunnel environments where evacuation can be challenging. Our junction box features genuine high-grade fire-resistant performance, effectively enhancing the fire protection level of your power distribution system.
The sealed enclosure prevents cable cores from exposure, meeting stringent safety regulations for underground installations.
Installation Benefits You'll Appreciate
Time and Cost Savings
Traditional junction installation requires careful pre-measurement, cable cutting, and lengthy preparation. Our system eliminates these steps. You save labor costs, reduce installation time, and minimize material waste.
Flexible Positioning
Adjust branch locations on-site based on actual conditions. This flexibility is invaluable when dealing with unexpected obstacles or design changes during construction.
Maintenance-Free Operation
Once installed, our enclosed design requires no regular maintenance. The integrated seal keeps contaminants out, and the uncut main cable design reduces potential failure points.
Enhanced Safety Standards
The complete encapsulation of cable connections eliminates exposed conductors. This meets strict safety requirements for public infrastructure and reduces electrical hazards in occupied spaces.
