The rubber-sheathed cable H05RN-F 2x0.75 50M from VDE-Kabel is a lightweight, flexible connection cable for electrical appliances, particularly suitable for areas with moderate mechanical stress. It is suitable for use in dry, damp, and wet rooms as well as outdoors, for example as a connection cable for garden equipment such as lawnmowers. The cable is oil- and fat-resistant, making it suitable for environments where it may come into contact with lubricants or similar substances.

Applications

The cable is primarily used for connecting electrical appliances that are not subject to continuous high mechanical loads but still require a certain degree of mobility and flexibility. It is intended for outdoor use, including garden equipment, and can be used in rooms with high humidity or temporary dampness. The construction also allows use in areas where the cable may come into contact with fats and oils without damaging the insulation or sheath.

Functions and Equipment in Detail

The cable consists of fine-stranded copper conductors of class 5, which are either bare or tinned. This construction ensures high flexibility and allows frequent bending without mechanical damage. The conductor insulation is made of a rubber compound according to VDE 0207 part 20, providing good electrical insulation and mechanical stability. The conductor identification follows VDE 0293-308, enabling clear identification of individual conductors. The outer sheath is made of a rubber compound according to VDE 0207 part 21 and is black, providing good visibility and resistance to UV radiation and mechanical influences.

Technology Explained Simply

The rated voltage is 300/500 V, meaning the cable is suitable for use in household and small installations typically operated at 230 V. The test voltage of 2000 V indicates the electrical strength of the insulation and ensures safety in case of overvoltage. The maximum operating temperature is +60 °C, with the cable tolerating temperatures from -25 °C to +60 °C during installation and from -40 °C to +60 °C after installation. This makes it suitable for locations with varying climatic conditions. The minimum bending radius is 7.5 times the cable diameter, enabling flexible handling. The flammability behaviour corresponds to test method B according to VDE 0472 part 804 (equivalent to IEC 332-1), ensuring limited flame spread in case of fire. The oil resistance according to VDE 0472 part 803 test method A and the ozone resistance according to VDE 0472 part 805 test method A and A1 test method C ensure a long service life even in aggressive environments.

Compatibility and Accessories

The cable is suitable for use with standard plugs and socket outlets designed for a rated voltage of 300/500 V. It can be connected to devices requiring a connection cable with two conductors (without protective earth conductor). The designation X" in the type designation indicates that no protective earth conductor (gn-ge) is present. For applications requiring a protective earth conductor, a corresponding variant with designation "G should be selected.

Installation and Mounting

The cable can be installed indoors and outdoors. During installation, a minimum bending radius of 7.5 times the cable diameter must be observed to maintain the cable's flexibility and integrity. Installation is possible in dry, damp, or wet rooms as well as outdoors, provided the temperature limits are respected. The cable is not designed for continuous exposure to high temperatures or mechanical stress.

Operational Advantages

The combination of flexible copper stranded conductors, oil- and fat-resistant sheath, and high electrical strength makes the cable a reliable solution for mobile and semi-stationary applications. The black-coloured rubber compound of the outer sheath provides good visibility and resistance to UV radiation, extending the service life outdoors. Compliance with standards VDE 0207, VDE 0293, and VDE 0472 ensures safe and standard-compliant use.
