Why do we need heat-resistant cables?
Of course, in some cases, needed. Let’s see if such a cable is needed on ordinary vehicles?
It is known that the normal operating temperature of a running engine is in the range of 80 – 90 ° C, and in some it is maximum – 105 – 110 ° C. These parameters are provided by the cooling system of the internal combustion engine. The coolant is pumped into the channels of the cylinder block, and if this is not enough, then the fan is turned on, which blows air to the radiator and thereby further cools the engine.
Nevertheless, some organizations are trying to give notice of the exceptional qualities of their cables (read, to increase the price) in order to add value, in their price lists they declare the sale of temperature-resistant (heat-resistant) control cables.
For example, the company NITavto LLC announces the sale of: CableCraft cable / heat resistant
Usually the control cable sheath (casing) and the inside (liner) are made of polymers, they do not have a clear melting point – they gradually soften over a wide temperature range.
Let’s see the available data, what temperature conditions of work are announced by well-known manufacturers of cable manufacturers and how this is achieved:
1. For the organization MORSE (Teleflexmorse), now this brand belongs to Kongsbergautomotiv, the data for the standard cable are as follows:
Standard Operating temperature – 40 ° С to + 100 ° С
For heat resistant cables, the data is there:
at temperatures up to a maximum of + 150 ° C
2. To organize CableCraft data for a standard cable, see here:
Operating temperature: from -65°F to +230°F (-53.89 °С to +110°С )
For a heat-resistant cable, the data here: http://www.cablecraft.com/pdfs/Blue_Max.pdf
Material: Nylon Covered Innermember
Operating temperature: from -65°F to +350°F (-53.89 °С to +176.67°С )
Please note: the color of this cable is bright blue (Blue Max cable)
3. For ORSCHELN, see here:
Data for Standard Cable – Standard Push-Pull Control Cable
Cable sheath, core material HEFT 2:
-65 ° F to + 225 ° F (- 53.89 ° С to + 107.22 ° С)
Heat resistant liner withstands:
temperature version at – 65 ° F to + 300 ° F (- 54 ° С to + 148.89 ° С)
But the material of the outer shell of the heat-resistant cable is NYLON
The most common and versatile heat-resistant polymer for technical needs is Teflon, it is also PTFE, polytetrafluoroethylene, which behaves absolutely calmly up to 300 ° С. Fluoroplastic properties here http://www.xumuk.ru/encyklopedia/2/4947.html
Pay attention to the color of such a cable – bright black (gloss black color)
As you can see, the standard cables of all manufacturers withstand the temperature of the working engine of the vehicle.
The company ConSys has the opportunity to offer you just such cables, or heat-resistant, in which the teflon coating of the cable sheath is applied.
