Tinning

The copper cable 70 Qmm 19x from VDE-Kabel is a fixed installation power and control cable designed for use outdoors, in the ground, indoors, and in cable ducts. It is used for transmitting electrical energy and control signals in industrial, commercial, and municipal installations. The cable consists of bare copper conductors manufactured according to VDE 0295, arranged in a multi-strand, round configuration (RM) with 19 individual strands each 2.1 mm in diameter. This construction ensures high flexibility and mechanical robustness, especially under frequent bending stress. The conductors are tinned in accordance with DIN 48201/1, which improves corrosion resistance and facilitates soldering. The core insulation is made of PVC, providing good electrical insulation and mechanical stability. Core identification follows VDE 0293-308; for this cable type, it is a version without a green-yellow protective conductor (O), suitable for applications where a protective conductor is not required. The outer sheath is made of black PVC, protecting the cable against external influences such as moisture, mechanical stress, and UV radiation.

Applications
This cable is suitable for use in underground installations, outdoor environments, and indoor spaces. It is commonly used in electrical installations, industry, machine and plant supply, and building electrical systems. Installation takes place in the ground, in cable ducts, or in other protected environments. The rated voltage is 0.6/1 kV, making it suitable for most industrial and commercial applications. The test voltage of 4 kV ensures electrical safety and reliability under load.

Functions and Equipment in Detail
The cable has a maximum operating temperature of +70 °C, allowing safe use under normal ambient conditions. During installation, the temperature must not fall below -5 °C; after installation, operation is possible from -30 °C. The bending radius is 12 times the cable diameter, typical for multi-strand conductors, enabling flexible installation. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning the cable does not produce flames or flame propagation beyond the test length during a fire test. This is important for safety in enclosed spaces and cable ducts.

Technology Explained Simply
The tinning of the copper conductors improves corrosion resistance, especially in moist or aggressive environments, and facilitates the soldering process. The multi-strand, round configuration (RM) provides high flexibility, which is advantageous when installing in tight or curved routes. PVC insulation offers sufficient electrical insulation and mechanical strength. The black-colored PVC outer sheath protects the cable against external influences such as moisture, mechanical stress, and UV radiation. Core identification according to VDE 0293-308 enables clear identification of cores, which is important for installation and maintenance.

Compatibility and Accessories
The cable is designed for use in underground installations, cable ducts, and indoor spaces. It is compatible with standard installation techniques and materials for power and control cables. It is used in conjunction with suitable cable lugs, cable ties, and other installation components designed for PVC insulation and copper conductors. It is not specifically designed for any particular brand or product series, but conforms to general standards and norms.

Installation and Mounting
Installation must consider the specified bending radii and temperature limits. The cable must not be excessively bent or stretched to avoid mechanical damage. Underground installation requires sufficient depth and protective measures against mechanical damage. In indoor spaces and cable ducts, proper securing and routing are required to ensure proper function and safety. Electrical connections are made using suitable cable lugs or soldered joints, with the tinning of the conductors enabling secure and durable connections.

Operational Advantages
The cable offers high electrical conductivity due to the use of pure copper and high mechanical strength due to the multi-strand design. PVC insulation and the black-colored outer sheath ensure long service life and high reliability. Flame retardancy according to VDE 0472 Part 804, test method B, enhances safety in enclosed spaces. Tinning of the conductors improves corrosion resistance and simplifies connection techniques. The combination of flexibility, robustness, and safety makes this cable a reliable solution for a wide range of applications.
