## Summary description

Heat-shrink cable joint Radpol MP-DM1R (ZRM-1) designed for splicing single-core cables with conductor ranges from 4×6 mm² to 4×25 mm². The product provides electrical insulation, mechanical protection and moisture sealing for low-voltage cable connections. Suitable for use in indoor and outdoor installations where a compact, sealed splice is required.

## Long description

Radpol heat-shrink joint MP-DM1R (ZRM-1) is designed for splicing single-core low-voltage cables with conductor combinations from 4×6 mm² to 4×25 mm². The compact sleeve provides electrical insulation, mechanical protection and moisture sealing for indoor and outdoor cable connections. Its heat-shrink design ensures a tight, durable cover over conductors and joints, reducing the risk of corrosion and ensuring stable performance in common installation conditions.
Advantages
The heat-shrink joint delivers reliable insulation and a sealed barrier against moisture and contaminants without bulky fittings. Its shrinkable polymer construction conforms to cable geometry for secure mechanical support and simplified installation. The product is suitable for both indoor and outdoor environments and maintains dielectric integrity across the specified conductor range. The design reduces the need for additional sealing materials and provides a compact, tidy splice.
Suitable for
Splicing single-core low-voltage power cables in building installations
Outdoor cable repairs and connections requiring moisture sealing
Compact, space-constrained junctions in distribution networks
Temporary or permanent joins in service and maintenance work
Key specifications
Conductor compatibility: single-core cable sets from 4×6 mm² up to 4×25 mm²
Function: electrical insulation, mechanical protection and moisture sealing
Construction: heat-shrinkable sleeve providing conformal coverage over joints
Application environment: suitable for indoor and outdoor installations
Design characteristic: compact sealed splice for low-voltage connections
How to use
Prepare cable ends by stripping insulation to the required length and making the electrical connection according to standard splicing practice. Slide the heat-shrink joint over the prepared conductors, ensuring correct alignment and overlap. Apply controlled heat evenly across the sleeve until the material shrinks and conforms tightly around the conductors and joint, forming a sealed barrier. Allow the assembly to cool and check that the sleeve has fully adhered and sealed the splice before restoring service.
Usage recommendations
Use a calibrated heat source suitable for polymer heat-shrink materials and follow local electrical safety standards during preparation and heating. Verify conductor compatibility with the specified range and ensure that mechanical stress relief and strain relief practices are applied where required. For prolonged outdoor exposure, inspect seals periodically and avoid direct flame contact to preserve material integrity.
