The Cellpack SMH5 1.5-6 is a shrink connection sleeve for the electrical connection of plastic cables. It is suitable for cables with insulations made of PVC, PE, and VPE, for example, for types such as N(A)YY, NYM, or TT. The sleeve is particularly used for connecting copper and aluminium conductors with crimp connectors. The shrink connection sleeve is designed for an operating voltage of 1 kV and can be used in various environments, including indoor and outdoor areas, in soil, in water, in installation shafts, and in empty conduits.

Applications

The SMH5 1.5-6 is universally applicable in electrical installation, particularly for connecting cables with cross-sections between 1.5 mm² and 6 mm². It is frequently used in building electrotechnics, machine and plant cabling, as well as in industrial electrical installations. The sleeve is suitable for use in damp, wet, or underground areas, as it provides permanent sealing and mechanical stability. Use in water or soil requires appropriate mechanical and electrical insulation, which is ensured by the shrink technology.

Functions and Equipment in Detail

The shrink connection sleeve is slipped over the conductors to be connected and then activated by applying heat (e.g., with a hot air blower). During this process, the sleeve shrinks and conforms tightly to the conductors, creating a dense, watertight, and mechanically stable connection. The sleeve is designed for connecting five conductors, each with a cross-section of 1.5 to 6 mm². The connection is made using crimp connectors mounted on copper or aluminium conductors. The sleeve ensures permanent electrical insulation and protects the connection from environmental influences such as moisture, dust, or mechanical stress.

Technology Explained Simply

Shrink technology is based on a thermoplastic material that changes shape and shrinks when heated. Before use, the sleeve is slipped over the conductors, which must already be connected with crimp connectors. After applying heat, the sleeve shrinks and forms a tight fit around the conductors, creating a sealed connection. The material technology used ensures high electrical insulation and mechanical strength. The sleeve is designed for an operating voltage of 1 kV, making it suitable for many applications in low-voltage technology. The connection cannot be disassembled after installation, as the material retains its shape after shrinking.

Compatibility and Accessories

The SMH5 1.5-6 is specifically designed for cables with insulations made of PVC, PE, and VPE. It is compatible with cable types such as N(A)YY, NYM, and TT. The sleeve is used with crimp connectors for copper and aluminium conductors. Use requires the availability of crimp connectors and a heating device to activate the shrink connection.

Installation and Mounting

Installation is performed by slipping the sleeve over the conductors already connected with crimp connectors. The sleeve is then heated using a hot air blower or similar device until it shrinks and forms a tight fit. Heat application must be even to ensure uniform shrinkage. After cooling, the connection is permanent and watertight. Installation requires no additional tools other than the heating device. The sleeve is suitable for use in various environments, including in soil, in water, and in installation shafts.

Operational Advantages

The SMH5 1.5-6 provides a reliable, durable, and watertight connection protected from environmental influences. The shrink technology ensures a tight fit that resists mechanical stress and moisture. The connection is electrically safe and designed for an operating voltage of 1 kV. The sleeve is easy to install and requires no additional tools other than a heating device. Its universal usability for various cable types and conductor materials makes it a flexible solution in electrical installation.
