Cable Jointing Resin: Professional Solutions for Low-Voltage Power Distribution
Xi'an OUKAMU Power Technology delivers industrial-grade Cable Jointing Resin systems backed by over 150 national invention patents and 20 years of cable connection expertise. Our ZR-JFZ-70/35 branch joint system supports main cables from 25~70mm² and branch cables from 2.5~35mm² at rated voltage 0.6/1kV. With proven performance across 10,000+ major projects including Hong Kong–Zhuhai–Macao Bridge and multiple metro systems, our resin joint kits eliminate the need to cut main cables, saving 2-3 meters of cable per installation while reducing labor costs by 40% and installation time significantly.
What Makes Our Cable Jointing Resin Different?
The technology of our product is a breakthrough in the area of T-connection systems for low-voltage electrical networks. Unlike standard jointing procedures that need the cables to be cut and pre-measured, OUKAMU’s solution maintains the integrity of the main cable during installation.
The two part polyurethane resin encapsulation provides excellent electrical insulation and mechanical protection. Your installation crew can quickly make on-site adjustments to branch placements for customisation. This versatility is essential for retrofit projects and difficult subsurface locations.
Our system conforms with the international safety standards of GB/T 14048.7-2016. The integrated design is suitable for PVC, XLPE, polyethylene and paper insulated cables, single core and multi-core.
Three Protection Levels for Every Application
Flame Retardant Protection
Our flame retardant solution is well suited for industrial and commercial buildings where normal indoor circumstances will allow for safe operation. The sealed design protects the main cable’s current-carrying capability and complies with fire safety rules for factories, residential buildings and public facilities.
IP68 Grade Waterproof Protection
We have a waterproof version for cable wells and direct burial applications that provides full moisture barrier protection. The complete potting method minimises water infiltration and leakage current, and guarantees steady performance when installed underground. This approach is suitable for underground railway system, tunnel lighting and outdoor distribution network.
Fire Resistant Protection
Our premium fire resistant system provides the highest level of safety for vital infrastructures. The upgraded formula ensures circuit integrity in the case of fire, meeting the rigorous criteria for hospitals, data centers and emergency power systems.

FAQ
Q: How long does the product take to cure?
A: The resin reaches touchable hardness within 24 hours under normal conditions (20-25°C). Full cure for load-bearing applications occurs at 72 hours. In colder environments, curing may extend slightly. The joint can remain workable for 15-20 minutes after mixing, giving your team adequate working time.
Q: Can I use this system on armored SWA cables?
A: Yes, our branch joint kits accommodate 2, 3, 4, and 5-core SWA armored cables from 10mm² through 300mm². The housing design provides ample working room for armored cable preparation. You'll strip armor at the branch point while maintaining main cable armor continuity.
Q: Do I need to cut the main cable for branch connections?
A: No cutting required. Our patented connector design clamps onto the main cable conductor through a controlled penetration method. This preserves main cable integrity and eliminates the risks associated with cable splicing. Your main circuit remains fully rated after branch installation.
Q: What makes resin jointing better than heat-shrink methods?
A: Resin encapsulation provides superior moisture sealing and mechanical protection compared to heat-shrink sleeves. You won't need heat guns or torches on-site, improving safety in confined spaces. The potted joint withstands higher mechanical stress and offers better long-term stability in underground applications.
Q: Is special training needed for installation?
A: Basic electrical qualification is sufficient. Our system eliminates complex splicing and specialized tooling. Standard installation takes 15 minutes per joint after brief familiarization. We provide installation guides and technical support to ensure your team's success.
Q: Can these joints be reused if I need to modify the circuit?
A: Our advanced design allows disassembly for circuit modifications. While the resin itself is single-use, the housing and connectors can accommodate reconfiguration. For temporary installations or pilot projects, this reusability offers significant value.
