Why Choose OUKAMU Insulating Cable Connectors?
Electrical distribution projects require connectivity solutions that balance performance, safety and ease of installation. The conventional methods of cable jointing need the primary conductors to be severed, which reduces their load capacity and increases the risk of failure.
The integrated branch connector technology of OUKAMU presents a new design solution to the above difficulties. Our method keeps the integrity of the main wire and enables safe branch connections wherever. Such a technique preserves the original cable carrying capacity and mechanical strength in the whole distribution network.
The patented piercing connection design removes the need to strip insulation. Installation teams can make connections quickly and easily, without the need for preparing specific cables, greatly decreasing labour costs and project schedules.
All of our connectors are fully encapsulated in high quality resin materials for IP68 level protection against moisture, dust and environmental contamination. Complete sealing makes them excellent for cable wells, direct burial and rugged underground locations.

Key Features and Benefits
Uncut Main Cable Design
Reliability of your distribution system hinges on preserving conductor continuity. Our Insulating Cable Connector maintains the integrity of the main cable without cutting or interrupting the flow of power. This design avoids the loss of current-carrying capability associated with typical ways of splices.
The uncut method also removes possible weak places where cable breakdowns are likely to happen. Minimise conductor cuts to minimise long-term maintenance and maximise overall system life.
Flexible Installation On Site
Conditions in the field are seldom as originally specified. OUKAMU connections let you to place branches anywhere without pre-measuring or custom manufacturing. Installers can alter the branch points to match the real site conditions when installing.
This versatility is helpful in renovation and retrofit projects. Teams may utilise existing distribution lines with little planning or downtime, minimising interruption to occupied facilities.
Improved Waterproof Protection
Most failures of underground cable are caused by moisture intrusion. Our resin encapsulated design gives you full waterproof sealing with an IP68 rating. The integrated housing ensures that there is no intrusion of water even if submerged continuously.
This level of protection allows our connections to be used in direct burial applications, cable wells and in flood-prone installations. Your distribution system is working reliably regardless of how much moisture is in the surroundings.
Excellent Flame Retardant Performance
“Fire regulations are getting tighter in all corners of the construction industry. UL94V0 flame retardant standards. OUKAMU connections will not allow fire to travel throughout the cable path. Fire-resistant variants offer additional protection for key circuits that must stay in service throughout the fire.
This enhanced flame resistance makes our products excellent for tunnels, high rise structures, hospitals and public infrastructure where fire safety is important.
