## Long description

The EM Group Heat-Shrinkable Through Joint ZRN1X4 is a professional-grade solution engineered for the reliable splicing and connection of 4-core power cables. Designed to accommodate cross-sections ranging from 16mm2 to 35mm2, this kit provides a robust method for extending or repairing electrical lines in demanding environments. By utilizing advanced heat-shrink technology, the joint creates a seamless, high-integrity connection that maintains the electrical and mechanical properties of the original cable.
Advantages
This through joint offers exceptional performance due to its high-quality materials that provide superior electrical insulation and mechanical strength. The heat-shrinkable components are specifically formulated to resist environmental stressors, including moisture, chemicals, and UV radiation, ensuring that the connection remains stable over time. Its design facilitates a straightforward installation process that effectively seals the cable against water ingress, making it an ideal choice for maintaining the safety and longevity of electrical distribution networks.
Suitable for
Underground power cable installations
Outdoor electrical distribution networks
Repairing damaged 4-core power cables
Extending cable runs in industrial or residential settings
When it may not be suitable
This product is not intended for use with cables outside the specified cross-section range of 16-35mm2. It is also not suitable for high-voltage applications exceeding the rated capacity of the kit or for specialized cables that require specific shielding or fire-resistant properties not provided by standard heat-shrink materials.
Key specifications
Cable type: 4-core power cables
Cross-section range: 16-35mm2
Technology: Heat-shrinkable
Protection: Moisture-resistant and mechanically robust
How to use
To install the joint, first prepare the cable ends by stripping the insulation according to the provided instructions. Connect the conductors using appropriate connectors, ensuring a secure electrical contact. Position the heat-shrinkable components over the connection area, ensuring they are centered correctly. Apply uniform heat using a gas torch or a suitable heat gun, starting from the center and moving outwards to shrink the material evenly and expel any trapped air. Allow the joint to cool completely before applying any mechanical stress or energizing the cable.
What to consider before purchase
Verify the cross-section of your cable matches the 16-35mm2 range
Ensure the cable is a 4-core type
Confirm you have the necessary tools for heat application
Check local electrical regulations for cable jointing requirements
Usage recommendations
Always ensure the cable surface is clean and free of debris before applying the heat-shrink components to guarantee a proper seal. Use a controlled heat source to prevent overheating or damaging the cable insulation.
