Our model ZR-JFZ-240/70 supports main cables from 95~240mm² and branch cables from 6~70mm², rated at 0.6/1kV. These joints eliminate the need to cut main cables, saving 2-3 meters of cable per installation while maintaining full load capacity. Successfully deployed in over 10,000 projects including Hong Kong-Zhuhai-Macao Bridge and multiple metro systems, our solutions deliver IP68 waterproof protection, flame retardant performance, and fire-resistant capabilities. Advanced resin encapsulation technology ensures reliable operation in underground burial, cable wells, and complex infrastructure environments.
What Are Cast Resin Joints For Armoured Cables?
Cast resin joints are a particular type of connection method for the low voltage power distribution networks with armoured wires. These couplings utilise two-part polyurethane or epoxy resin castings to effect waterproof, insulated, connections between the main wires and branch circuits.
Our resin couplings allow branches to be joined without having to cut the main conductor as is the case with traditional jointing methods. It keeps the original current-carrying capacity and mechanical strength of the cable, and considerably reduces the time of installation and material waste.
The resin casting method offers for complete encapsulation of all electrical connections. This creates a long-lasting barrier to moisture, dust and environmental pollutants that provides long term reliability in tough applications.
Key Features and Technical Advantages
Flexible Onsite Installation
Our branch joints can be installed wherever you choose – no need to pre-measure or customise. The branch location can be flexibly adjusted during installation, making installation speedier and more adaptive to real-world settings.
This flexibility is essential when dealing with existing infrastructure or during development when alterations are required. You save a lot of time compared to traditional methods, which require perfect measurements and pre-made parts.
Waterproof Protection
We have the built-in sealing design on the joints with IP68 protection certified. The complete resin encapsulation guarantees no water infiltration even in continuous immersion, which makes them excellent for underground direct burial, cable wells and flood prone areas.
Its waterproof characteristics allows for safe operation in tunnels, basements and outdoor installations where exposure to moisture is inevitable. Your electrical system is protected for the life of the service.
Flame Retardant and Fire Resistant Options
OUKAMU also offers specialised fire-resistant versions that exceed higher safety standards. These couplings provide electrical integrity during fire exposure and also buy essential time for emergency reaction and evacuation.
Flame retardant qualities meet the specifications of GB/T 14048.7-2016 and international safety standards. You may be confident your installation complies with the rigorous fire safety requirements for commercial and public buildings.
Cost Effective Solution
By avoiding the need to cut main wires you save 2-3 meters of pricey armoured cable at each connection point. Less technical skill and time are needed for streamlined installation procedures, so labour expenses are substantially reduced.
Maintenance free design which reduces long term operational costs. After installation these joints do not require frequent inspection or service, thus minimising the total cost of ownership over the life of the system.
