Core Product Advantages
Easy Installation and High Construction Efficiency
The modular design philosophy reduces your installation complexity significantly. You won't need specialized tools or extensive training. The intuitive assembly process cuts on-site installation time by up to 40% compared to traditional splice methods. This translates directly into lower labor costs and faster project completion.
Conductors connect within precision-engineered terminal slots. This design ensures consistent, reliable electrical joints every time. Your installation teams can work confidently, knowing the connection quality meets demanding specifications.
Excellent Sealing Performance
The dual-layer protection system sets this product apart. Gel-filled insulation forms the first barrier, conforming perfectly to cable surfaces and conductor interfaces. The outer resin encapsulation then creates an impermeable shell.
This combination achieves genuine IP68 protection. Your connections remain secure even when submerged in water at 1.5 meters depth for extended periods. Moisture ingress, the primary cause of splice box failure, becomes virtually impossible.
Suitable for Harsh Environments
Outdoor installations present unique challenges. UV radiation degrades many materials over time. High humidity accelerates corrosion. Temperature extremes stress components.
The OKJX-150 addresses these concerns through material selection and design. The high-strength engineering enclosure resists UV damage, maintaining structural integrity through years of sunlight exposure. Corrosion resistance ensures performance in coastal areas and industrial environments. The operating temperature range from -25°C to +40°C accommodates most climate conditions worldwide.
Low Operation and Maintenance Costs
Your long-term costs matter as much as initial investment. This splice box minimizes lifetime expenses through several features.
The sealed design eliminates routine inspection requirements. You won't need to open connections for cleaning or apply protective compounds. The stable electrical performance means fewer service calls and reduced downtime.
When network expansion becomes necessary, the flexible design accommodates modifications. You can add branch connections without replacing the entire system. This adaptability protects your infrastructure investment as requirements evolve.
Technical Features in Detail
High-Strength Engineering Material
The enclosure utilizes advanced thermoplastic compounds engineered for electrical applications. These materials provide excellent mechanical strength, withstanding installation stresses and ground pressure in buried applications. Impact resistance prevents damage during handling and protects against accidental strikes during nearby excavation work.
Resin-Encapsulated Splice Box The insulating properties of the enclosure material complement the internal protection systems. You benefit from multiple layers of electrical isolation, reducing risks in fault conditions.
Compatibility with Various Cable Sizes
Infrastructure projects rarely involve uniform cable specifications. Distribution networks branch to different load areas using various conductor sizes. The OKJX-150 accommodates this reality.
The terminal system accepts main cables from 50mm² to 150mm² cross-sections. Branch connections adapt to your specific requirements. This flexibility means you can standardize on one splice box model for diverse applications, simplifying inventory management and reducing procurement complexity.
Application Environments
This connector solution excels in demanding installation scenarios:
Underground Wells: The compact footprint fits standard junction boxes. IP68 sealing protects against water accumulation and humidity.
Direct Burial: The robust enclosure withstands soil pressure and resists chemical exposure from ground conditions. No additional protective enclosures are necessary.
Municipal Infrastructure: Urban power distribution networks benefit from the concealed installation capability and long service life. Reduced maintenance requirements minimize traffic disruption.
Highway and Railway Projects: Vibration resistance and environmental protection make this solution ideal for transportation infrastructure requiring reliable power distribution.

FAQ
Q: How does the OKJX-150 achieve IP68 protection rating?
A：The IP68 rating results from our dual-layer protection approach. Gel-filled insulation creates the primary moisture barrier, conforming to irregular cable surfaces and eliminating air gaps. The outer resin encapsulation then forms a rigid, impermeable shell. Together, these layers prevent water ingress even under continuous submersion conditions. Testing per IEC 60529 standards validates this protection level.
Q: What is the expected service life in direct burial applications?
A：Under normal operating conditions, you can expect 25+ years of maintenance-free service. The enclosure materials resist UV degradation, chemical exposure from soil conditions, and mechanical stress. Thermal aging tests and accelerated environmental exposure studies confirm long-term stability. Unlike metal junction boxes, corrosion doesn't compromise enclosure integrity over time.
Q: Can this splice box accommodate mixed cable types and sizes?
A：Yes, the terminal system handles main cables from 50mm² to 150mm² conductor cross-sections. Branch connections can vary in size according to your distribution requirements. This flexibility allows single-product standardization across projects with diverse specifications, simplifying procurement and inventory management while maintaining performance.
Q: What tools are required for installation?
A：The modular design minimizes tool requirements. Basic cable preparation tools (cutters, strippers) and standard hand tools suffice for most installations. You won't need specialized crimping equipment, heat application systems, or torque-calibrated wrenches. This simplicity reduces training requirements and allows field teams to work efficiently.
Q: How does resin encapsulation compare to heat shrink methods?
A：Resin encapsulation provides superior mechanical protection and moisture barrier properties. Heat shrink systems depend on proper application technique and can fail if air pockets remain or heating proves insufficient. Resin encapsulation eliminates installation variability, ensuring consistent protection regardless of installer experience. The rigid enclosure also provides better physical protection against impact and ground pressure.
Q: Is the product suitable for high-altitude installations?
A：The OKJX-150 operates reliably in altitudes up to 4000 meters. For installations above 1000 meters, consider environmental factors per IEC standards, but the sealed design and insulation system accommodate reduced air density conditions. The enclosure maintains mechanical strength and electrical performance across elevation ranges.
Q: What maintenance procedures should we plan?
A：The sealed design eliminates routine maintenance requirements. Annual visual inspections verify physical condition and connection integrity. Thermal imaging can detect load imbalances or connection degradation, though the stable terminal design minimizes these concerns. Unlike oil-filled or open-junction systems, you won't need periodic cleaning, seal replacement, or compound reapplication.
