Rubber cable
Rubber cables for device connection
Rubber cable is a common term for device cables because they generally have a rubbery sheath. Such wires are, as the name suggests, used to connect electrical devices.
The properties of a rubber cable can vary greatly. For example, rubber cables differ in terms of properties such as low flammability, resistance to oil and grease, and resistance to acids, UV radiation and high and low temperatures.
Popular standard types of rubber-sheathed cables
Several particularly robust cable types with a rubber sheath are offered under the designation of rubber-sheathed cables. They include the rubber-sheathed cables H05RN-F (300/500 V) and H07RN-F (450/500 V). The H07RN-F wire, in particular, is completely water-tight and suitable for installation underground. This sheathed cable is resistant to oil, grease and direct UV radiation and withstands moderate mechanical stress. Such cables are used for setting up construction sites, on factory premises and for the connection of heavy motors, equipment and machines.
The H05RN-F rubber cable is also suitable for use outdoors, but is intended for lower mechanical stress. It can, for example, be used for the connection of gardening tools.
Rubber-sheathed cables for construction and industry
The H07BQ-F rubber-sheathed cable is a wire with a PUR sheath that is also referred to as an armoured cable. It is characterised by extreme resistance to mechanical stress. Therefore, it is popular for use as a construction cable. The rubber cable is resistant to seawater, oil, ozone and UV as well as very low and high temperatures. It is also highly abrasion-resistant and incision-resistant. Therefore, this cable is resistant to all the stresses to which a cable is normally exposed.
The H05BQ-F cable resembles the H07BQ-F, but is used to connect electrical equipment and machines at lower voltages.
Heavy rubber-sheathed cables NSSHÖU and NSGAFÖU
The cables NSGAFÖU and NSSHÖU also rank in high performance classes. The NSSHÖU is a wire for nominal voltages up to 1.8/3 kV. It is mostly used for short-circuit- and earth-leakage-proof installation and for switchgears and distributors up to 1000 V. Machines and equipment in industry, on construction sites and in mining are also connected to such wires.
The NSGAFÖU can also be used up to the region of 1.8/3 kV. This is a flame-retardant wite that is often used in buses and rail vehicles as well as in dry rooms. This cable too is regarded as short-circuit- and earth-leakage-proof in switchgears and distributors up to 1000 V. These examples demonstrate that suitable rubber cables are also available to meet very high demands.
