Key Performance Features
Uncut Main Cable Design
Your primary trunk cable is fully untouched during installation. This innovative method retains the complete current carrying capability and the mechanical strength of the entire wire system.
The continuous conductor design eliminates potential points of failure. You benefit from the increased reliability of important power distribution networks in commercial buildings, industrial facilities and subterranean installations.
Advanced Waterproof Protection
OUKAMU Cable Resin Joint systems utilise total encapsulation of the resin technology. Integrated sealing design to prevent water intrusion, moisture penetration and electrical leakage in harsh conditions.
All these applications require the IP68 certified joints to work reliably: cable wells, direct burial or submerged environments. These systems can be successfully applied in basements, tunnels and outdoor substations.
Fire Resistant & Flame Retardant Options
Our specially formulated products give you true fire resistant performance. The polymeric composition maintains insulating qualities even under fire conditions hence improving the overall system safety.
You are enjoying a less risk of fire spread along cable routes. This makes OUKAMU joints the perfect solution for high-rise buildings, public institutions, hospitals and metro stations where fire safety is of the utmost importance.
Benefits of Flexible Installation
No pre-measurement or tailoring necessary. During building, your installation crew places branch connections exactly where you want them to be.
Snap-to-close housing design allows for rapid assembly. Most installations are completed 30-50% faster than traditional jointing methods, lowering project deadlines and labour costs.
Application Scenarios
OUKAMU cable branch joints serve diverse industrial and civil construction projects:
Commercial Buildings: Distribution networks in shopping malls, office towers, and hotels benefit from space-saving design and maintenance-free operation.
Residential Complexes: Multi-story apartment buildings utilize our joints for flexible floor-by-floor power distribution without main cable interruption.
Infrastructure Projects: Metro systems, railway stations, and highway lighting rely on our waterproof and fire-resistant solutions for long-term reliability.
Industrial Facilities: Manufacturing plants, warehouses, and processing centers gain from robust mechanical protection and chemical resistance in harsh environments.
Underground Applications: Direct burial installations and utility vaults depend on our IP68-rated protection against groundwater and soil moisture.
Installation and Material Benefits
You save a lot of cost by using less material. The uncut main cable method saves 2-3 m of pricey conductor for each branch point.
Productivity increases tremendously. Simple installation processes require less specialised training and speedier completion frees your workforce for further tasks.
The design is repeatable for relocation or alteration when construction changes. This flexibility means less waste and the ability to make last-minute design changes without loss of material.
Compact joint dimensions for optimal space. You maximise usable area in cable trays, conduits and in restricted installation locations.
FAQ
Q: What makes OUKAMU product different from soldered connections?
A: Traditional soldering requires cable cutting, tinning, heat application, and insulation wrapping. Our resin joint system eliminates these steps through mechanical connectors and resin encapsulation. You avoid heat-related damage to cable insulation while achieving superior waterproof performance that electrical tape cannot provide.
Q: How quickly does the resin cure in cable joints?
A: OUKAMU two-part polyurethane resin achieves initial cure within 2-4 hours at 21-27°C ambient temperature. Full mechanical strength develops within 24 hours. For faster curing, you can apply gentle heat using infrared lamps or work in warmer environments. Humidity levels affect curing speed—lower humidity accelerates the process.
Q: Are OUKAMU resin joints truly waterproof for underground installation?
A: Yes, absolutely. Our joints achieve IP68 rating through complete resin encapsulation. Properly cured resin exhibits extremely low water absorption (less than 0.1%). The monolithic seal prevents moisture ingress even under continuous submersion. This makes our joints perfect for direct burial, cable wells, and locations with high groundwater tables.
Q: What considerations matter when selecting cable joints for specific projects?
A: Match the joint specifications to your cable type, conductor size, and voltage rating. Consider environmental factors like moisture, temperature extremes, and chemical exposure. Our joints accommodate single-core and multi-core cables from 2-core to 5-core configurations. Evaluate installation accessibility and future maintenance requirements. OUKAMU solutions offer tool-free installation advantages for confined spaces.
Q: Can the branch position be changed after installation?
A: The resin encapsulation creates a permanent connection once cured. However, our design allows initial flexible positioning during installation before resin application. You can adjust branch cable routing and connector placement to match actual site conditions without pre-fabrication constraints. This flexibility eliminates costly rework from measurement errors.
Q: What are effective tips for optimal resin curing performance?
A: Maintain workspace temperature between 21-27°C for best results. Mix resin and hardener according to exact ratios specified in instructions—typically 30-45 seconds of thorough mixing. Apply resin in consistent layers to avoid air bubbles. Ensure cable surfaces are clean and dry before installation. Lower humidity environments produce faster, more reliable curing with enhanced bond strength.
