Cable Waterproof Joint

Cable Waterproof Joint – IP68 Waterproof Branch Connection System

Xi'an OUKAMU Power Technology Co., Ltd. presents the T-GJFZ-16/10 Cable Waterproof Joint, engineered with over 20 years of specialized expertise in branch cable connection technology. This innovative solution features IP68-rated waterproof protection with gel-filled insulation and dual safety mechanisms. Designed for main cables 4~16mm² and branch cables 1.5~10mm², the system eliminates the need to cut main cables or pre-measure installation lengths. Successfully deployed across 10,000+ infrastructure projects including the Hong Kong–Zhuhai–Macao Bridge and multiple metro systems, OUKAMU's patented technology (150+ national invention patents) delivers cost-effective, maintenance-free performance for underground burial and concealed installations.

What Makes Our Cable Waterproof Joint Different?

OUKAMU's product stands apart through its uncut main cable design. You can install branches anywhere along your power distribution line without disrupting the main conductor's integrity.

Traditional jointing methods require cutting main cables, which reduces current-carrying capacity and introduces potential failure points. Our patented T-connection technology preserves full mechanical strength and electrical performance.

The gel-filled encapsulation process creates complete insulation and waterproof protection. This integrated sealing design prevents water ingress and electrical leakage, ensuring safe operation in cable wells, direct burial applications, and harsh underground environments.

Parameters

Key Features and Benefits

100% Waterproof Protection

Our gel-filled insulation technique offers outstanding moisture barrier performance. The integrated housing design is IP68 rated, designed for long-term submersion and direct burial installations.

You don't have to worry about water damage or loss of insulation. The encapsulation design provides complete protection of all conductors against the environment.

Flexible On-Site Installation

During construction the installation site can be easily modified. No need to pre-measure or customise before coming to site.

This flexibility greatly decreases labour costs and project schedules. Your installation team will be able to adjust branch locations to match what is actually out in the field rather than fixed measurements.

Cable Performance Continues

Not cutting the main cable also gives you its original current capacity. The entire cable service life is extended while retaining mechanical strength.

Fewer connection points mean reduced risk of hotspots or resistance issues. Your power distribution system runs at intended efficiency levels.

Economical Solution

Reduced material costs versus conventional junction box approaches. Less installation time translates into immediate labour savings.

Maintenance-free design means no repeated inspection and repair costs. The return on the investment is better during the lifespan of the system.

Application Scenarios

OUKAMU waterproof branch joints serve diverse low-voltage distribution applications across multiple industries.

Infrastructure Projects: Metro systems, railway stations, highway lighting, and tunnel construction benefit from reliable underground connections that withstand moisture and mechanical stress.

Commercial Buildings: Shopping centers, office complexes, and hotels require flexible branch connections for evolving electrical layouts without disrupting main power feeds.

Industrial Facilities: Manufacturing plants, warehouses, and processing facilities need robust connections that maintain uptime in challenging environments with temperature variations and humidity.

Residential Developments: Multi-story buildings and housing complexes use these joints for efficient vertical and horizontal power distribution with minimal space requirements.

Installation Process

The installation process does not require special equipment or substantial training.

First, determine where you want the branch to be located along the main cable run. Remove the insulation from the branch cable cores in accordance with specifications.

Connect the branch conductors to the main cable with the integrated connector system. Proper wire routing is possible with this design without sharp bends or stress spots.

Fill the housing with the two part gel resin ensuring that all connections are totally enclosed. Seal the housing tight and allow adequate cure time following manufacturer specifications.

The entire treatment takes less than 30 minutes each joint. Your installation crew can deal with several connections effectively within one work shift.

Quality and Reliability

OUKAMU maintains rigorous quality control throughout manufacturing. Each component undergoes testing for electrical performance, mechanical strength, and environmental resistance.

Our products comply with international low-voltage electrical standards. The gel resin formulation provides excellent adhesion to PVC, XLPE, and polyethylene insulation materials.

With successful application in major infrastructure projects across China, our Cable Waterproof Joint systems have proven their durability under real-world conditions. Thousands of installations continue operating without failure after years of service.

The company's 150+ national invention patents demonstrate continuous innovation in cable connection technology. This intellectual property portfolio ensures you receive cutting-edge solutions backed by protected designs.

FAQ

Q: Can I use these joints with different cable types?

A: Yes, OUKAMU waterproof joints are compatible with polymeric cables including PVC and XLPE insulation. They work with both stranded and solid conductors in single-core and multi-core configurations.

Q: What if I need to make multiple branches from one main cable?

A: You can install multiple branch joints along the same main cable run. Each joint operates independently while maintaining the main cable's continuous conductor path.

Q: How long does the gel resin take to cure?

A: Typical curing time ranges from 30 minutes to 2 hours depending on ambient temperature. Full mechanical strength develops within 24 hours. You can energize the circuit after initial curing completes.

Q: Do these joints require periodic maintenance?

A: No, the sealed design is maintenance-free. Once properly installed, the encapsulated connections remain protected throughout their service life without need for inspection or resealing.

Q: What makes this different from heat shrink joints?

A: Unlike heat shrink solutions requiring special tools and careful heating procedures, gel-filled joints install with simple mixing and pouring. The resin self-levels around all connections for complete coverage without voids.

Q: Can I install these joints in direct burial applications?

A: Absolutely. The IP68 rating certifies suitability for continuous submersion and direct soil burial. The housing resists corrosion and mechanical damage from surrounding materials.
