High Temperature Cable
High temperature cable is a cable whose conductor material is multi-stranded soft copper conductor. "High temperature cable is a kind of special cable, high temperature resistant cable is mainly used for AC rated voltage 450/750V and below electrical instrumentation connection line and automatic control system transmission line.
It is called high-temperature cable because of its high-temperature-resistant property..." Heat-resistant and high-temperature wire and cable are generally determined by two needs. The first is a wire cable with a high ambient temperature, the cable is able to transmit signals or electrical energy normally under high temperature for a long period of time; the other is a power transmission cable, mainly to increase the interception capacity as the main purpose. High-temperature cable is a special cable, because it has the characteristics of high temperature resistance, so it is called high-temperature cable.

Development
General wire and cable are insulated and sheathed with plastic and rubber, which are conventional engineering materials with abundant sources to meet mass production and relatively low cost. But for some special industries such as petrochemical, iron and steel, aerospace, shipbuilding, military, pharmaceutical, food, plastic machinery, boilers and other heat and high-temperature related industries, need to be able to withstand a certain higher temperature of the wire and cable, ordinary wire and cable can not be used, need to be able to withstand high temperatures in order to ensure that the safe operation of its power and signal wire and cable.
With the rapid development of China's economy, the special industry demand for high-temperature cable has shown a high rate of growth step off, heat-resistant and high-temperature cables at a rate of 20% per annum, high-temperature cables as an important part of the special cables, has a strong vitality, demand exceeds supply, China imports about two billion yuan per year from abroad for domestic construction.
Conductor material: multi-strand soft copper conductor;
Insulation material: fluoroplastic insulation, temperature range -60-260 degrees;
Filling material: glass fibre;

Fire prevention measures
Adopt flame retardant cables. Adopt fireproof cable tray. Adopt fireproof coating. Install fireproof partition walls and fireproof baffles at cable tunnels and mezzanine exits. Exhaust cable should avoid oil pipeline, explosion-proof door, otherwise it should take local pipe penetration or heat insulation fire prevention measures.
1.AC rated voltage: U0/U 450/750KV.
2. Maximum working temperature: polyperfluoroethylene propylene (F46) insulation does not exceed 200℃, soluble polytetrafluoroethylene (PFA) insulation does not exceed 260℃.
3. Minimum ambient temperature: PVC sheath: fixed laying -40℃, non-fixed laying -15℃, fluorine plastic and silicone rubber sheath: fixed laying -60℃, non-fixed laying -20℃.
4. Cable installation and laying temperature should not be less than 0 ℃ (fluorine plastic, silicone rubber and composite sheath cable not less than -25 ℃).
5. Allowable bending radius of the cable: non-armoured cable is at least 6 times the outer diameter of the cable, copper tape shielded or steel tape armoured cable is at least 12 times the outer diameter of the cable, fluorine plastic insulation and sheathed cable is at least 8 times the outer diameter of the cable.
Precautions
In the process of transport loading and unloading, should not make the cable and cable disc damage, it is strictly prohibited to push the cable disc directly from the car, the cable should not be placed on the flat transport, flat storage. Before transporting or moving the cable disc, it is necessary to ensure that the cable disc is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed and should not be damaged, and the pressure oil tank should be firm, and the pressure indication should meet the requirements.
Main performance
The most significant performance of high temperature resistant cables is, first of all, high temperature resistance. The insulation, winding, filling and sheath of high temperature cables generally use fluoroplastics, silicone rubber, glass fibre, mica and other materials with strong high and low temperature resistance, which not only has strong high temperature resistance, but also has a certain ability to resist low temperature.
When the operating environment of the cable is relatively harsh, the performance of ordinary cables will be greatly reduced or destroyed, affecting the normal use of the cable, high-temperature cable insulation and high-temperature resistance, to ensure that the cable in the high-temperature operating environment of the cable performance is not destroyed, to ensure that high-temperature cable normal use.
High-temperature resistant cables are used in the field of electronics industry: temperature compensation wire, low-temperature resistant wire, high-temperature heating wire, aging-resistant wire, flame-retardant wire and so on;
High-temperature resistant cable in the field of household appliances industry for: air conditioning, microwave ovens, electronic sterilisation cabinets, electric rice burgers, electronic hot water bottles, electric heaters, electric ovens, electric frying pans, lamps and lanterns lighting and other internal wiring;
High-temperature resistant cable in the enterprise high-temperature environment can be used for: boiler room, rolling mills, fax machines, printers, photocopiers, scanners and other machines of the internal connecting lines, instrumentation motor wiring, electronics, gas equipment and other high-temperature environment.
High-temperature resistant cables are also widely used in petrochemical, steel, aerospace, shipbuilding, military, pharmaceutical, food, plastic machinery, boilers and other heat and high-temperature related industry sectors.
Ordinary cable in use for a period of time, easy to become aging by the environmental impact, so that the performance parameters of the cable have a different degree of reduction, but high-temperature cable because of its advanced manufacturing process, making its anti-aging ability is very strong, can be used for a long time and will not be aging, on the whole, to enhance the service life of the cable.
Characteristic use
High-temperature cable refers to cables that can operate normally in high-temperature environments, usually refers to cables that can safely and stably transmit power signals and data signals at high temperatures above 200℃ or even above 600℃. High temperature cables usually have the following characteristics:
1. high temperature resistance: high temperature cable materials must be able to maintain electrical properties and mechanical properties in high temperature environments, and have good heat resistance, flame resistance and oxidation resistance.
2. Anti-corrosion and corrosion resistance: high temperature environment not only to withstand high temperatures, but also corrosion, oxidation and other conditions, so high temperature cable must have a strong corrosion and corrosion resistance.
3. low energy consumption: high-temperature cables should have low resistance, reactance and capacitance, etc., in order to ensure that the energy consumption under high voltage is small, safe and reliable.
4. anti-interference: in the high temperature environment, it is easy to electromagnetic interference, so high temperature cable must have good anti-interference performance to ensure the stability of signal transmission.
High-temperature cables have a wide range of applications, especially in high-temperature melting, power transmission, aerospace, nuclear energy and other important fields. In addition, with the rapid development of new energy vehicles and intelligent manufacturing, high temperature cables will also emerge more application scenarios.
Usage Model
Widely used in aerospace, rolling stock, energy, iron and steel, non-ferrous metal smelting, oil mining, electrical machinery and other fields. Long-term continuous operating temperature of 125 degrees, 135 degrees, 150 degrees, 180 degrees, 200 degrees, 250 degrees and 250 degrees above the high-temperature-resistant cables, currently in common use are irradiated joint polyolefin stems, silicone rubber, fluorine resin, polyimide, mica, magnesium oxide and other cable.
Maximum resistance
Before talking about high temperature cables, it is necessary to understand what the operating temperature of ordinary wires and cables is. Usually, the common insulation materials for ordinary cables are polyethylene, polypropylene and polyvinyl chloride, etc., and cables made of such materials are generally able to operate at 70C~90C for a long time.
The insulation layer of high temperature resistant wire is used PA Teflon, it is because this material has a very good high temperature resistance, so it makes its production of wire can be in 180 ° C and above the environment of long-term operation. If you want to talk about the maximum number of degrees of high temperature wire can withstand, it is 200C. However, at 200C high temperature, even high temperature wire can not run for a long time, can only run for a shorter period of time, otherwise it is also prone to failure.
