## Summary description

The EM Group ZRN2X4 is a heat-shrinkable through joint designed for reliable electrical connection of 4-core power cables with a cross-section of 25-70mm2. This kit provides excellent insulation, mechanical protection, and moisture resistance for cable joints in various industrial and residential electrical installations. It ensures long-term durability and safety for underground or outdoor cable systems.

## Long description

The EM Group ZRN2X4 is a professional heat-shrinkable through joint engineered for the secure and reliable connection of 4-core power cables. Designed to accommodate cable cross-sections ranging from 25mm² to 70mm², this kit provides a robust solution for maintaining electrical continuity in power distribution networks. The assembly utilizes high-quality heat-shrink materials that react to thermal application to form a tight, protective seal around the cable splice, ensuring long-term performance in demanding environments.
Advantages
This through joint offers exceptional electrical insulation properties, effectively preventing short circuits and leakage currents at the connection point. The heat-shrink technology provides superior mechanical protection against physical stress, vibration, and abrasion, which is essential for maintaining the integrity of underground or exposed cable runs. Furthermore, the material is highly resistant to moisture, chemicals, and environmental factors, ensuring that the internal connection remains dry and corrosion-free throughout its service life.
Suitable for
Connecting 4-core power cables in residential electrical systems
Industrial power distribution and infrastructure projects
Underground cable installations
Outdoor electrical networks requiring moisture protection
When it may not be suitable
This product is specifically designed for 4-core cables within the 25-70mm² range and is not compatible with cables outside of these specifications or different core configurations. It should not be used in high-voltage applications exceeding the rated limits of the insulation material.
Key specifications
Cable type: 4-core power cable
Cross-section range: 25mm² to 70mm²
Technology: Heat-shrinkable
Protection: Moisture-resistant and mechanically durable
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 mechanical and electrical bond. Position the heat-shrink components over the joint area, ensuring they are centered correctly. Apply uniform heat using a gas torch or a heat gun, starting from the center and moving outwards to allow air to escape and the adhesive to bond effectively with the cable jacket. Allow the joint to cool completely before applying any mechanical stress.
What to consider before purchase
Verify the exact cross-section of your cables to ensure they fall within the 25-70mm² range
Ensure you have the necessary tools, such as a heat gun or gas torch, for proper installation
Confirm that the cable type is compatible with heat-shrink technology
Usage recommendations
Always follow local electrical safety regulations and manufacturer guidelines during installation. Ensure the cable surface is clean and free of debris before applying the heat-shrink components to guarantee a proper seal.
