High-temperature resistant wire and cable is a cable that can normally transmit signals or electrical energy at high temperatures. Long-term continuous operating temperature of 125 degrees, 135 degrees, 150 degrees, 180 degrees, 200 degrees, 250 degrees and more than 250 degrees is called high-temperature-resistant wire and cable, currently in common use are irradiated cross-linked polyolefin, silicone rubber, fluorine resin, polyamideimide, mica, magnesium oxide and other wires and cables. Heat-resistant wire and cable and high-temperature wire and cable need to meet two needs. This is a wire and cable ambient temperature is high, the cable in the long term at high temperatures can be normal transmission of signals or electrical energy, the other is the power transmission cable, mainly to increase the interception capacity as the main purpose.
High temperature resistant cable features
Excellent corrosion resistance, oil resistance, resistance to strong acids, strong alkalis, etc.; excellent electrical insulation properties, high temperature resistance, high frequency loss is small, does not absorb moisture, insulation resistance; excellent flame retardant, aging resistance, long service life.
There are two main categories of high temperature resistant cables
1, fluorine plastic wire and cable is: polyperfluoroethylene propylene (FEP, commonly known as F46), polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene copolymer (ETFE, commonly known as F40), polyvinylidene fluoride (PVDF). Fluorine plastic cables are mainly: high-temperature communication cables, high-temperature pilot line and installation line, high-temperature compensation wire and industrial high-temperature power and control signal cables, radiation-resistant cables for atomic reactors and rolling stock wires.
2, silicone rubber insulated wire and cable: silicone rubber has a better heat resistance. Wire and cable commonly used silicone rubber for methyl vinyl silicone rubber, the operating temperature scale is -60 ℃ ~ 180 ℃. Silicone rubber has a better zigzag function and low-temperature function, not easy to damage and cracking, these functions are generally high-temperature cables do not have, so the silicone rubber cable has a wide range of applications, has been a highlight of the high-temperature cable. Silicone rubber cable in high temperature mobile cable, soft, motor lead wires, low-temperature environment of high temperature operation places.
High-temperature resistant cable models
1, polyethersulfone insulated cable
Excellent heat resistance, physical and mechanical, electrical insulation, extrusion molding, at high temperatures, to maintain stable performance and other advantages, the heat distortion temperature of 200-220 degrees, the continuous use of the temperature of 180-200 degrees, ul temperature index of 180 degrees. Resistant to 150-160 degrees hot water or steam, not subject to acid, alkali erosion. Modulus of elasticity at 100-200 degrees almost unchanged, small coefficient of linear expansion, small temperature dependence, non-toxic, recognized by the U.S. DA, self-extinguishing, without adding any flame retardant.
2、Polyetheretherketone insulated cable
Polyether ether ketone belongs to the super heat-resistant thermoplastic resin, long-term continuous use temperature of 250 degrees, ul temperature index of 250 degrees. peek is a flexible resin, creep resistance, self-extinguishing, and do not add any flame retardant can meet the requirements.
3、Heat-resistant silicone rubber insulated silicone rubber sheathed cable
Applicable to household appliances, lighting fixtures, combustion equipment and other high-temperature environment. Divided into tin-plated copper-core silicone rubber insulated high-temperature flexible cable, tin-plated copper-core silicone rubber insulated braided shielded high-temperature flexible cable, tin-plated copper-core silicone rubber insulated high-voltage line, tin-plated copper-core silicone rubber insulated medium-sized rubber sheathed flexible cables, tin-plated copper-core silicone rubber insulated heavy-duty rubber sheathed flexible cables.
