Multicore flexible cables are a kind of sheathed wire, its full name is copper core PVC insulated PVC sheathed flexible cable. Generally used for flexible cables for fixed installation.
Are multicore flexible cables oil-resistant? The use environment of multicore flexible cables are generally good, and there is no oil pollution, so ordinary multicore flexible cables are not oil resistant.
If this cable is installed in an oily environment, you can choose oil-resistant unshielded flexible cable or oil-resistant sheathed flexible cable.They are also PVC insulated, but this kind of PVC has oil-resistant properties.
1.Oil-resistant unshielded flexible cables are a weak signal measuring cable, suitable for special working environments such as static electricity and fuel tanks. It has anti-static, oil-resistant, anti-stretch, and anti-bending characteristics. The small bending radius of the cable Zui is not less than 5 times the cable diameter. The cable can withstand a maximum tensile force of 200kg, and the number of winding, bending, and unwinding of the cable is more than 3000 times.
2. Oil-resistant unshielded flexible cables are suitable for industrial and mining enterprises such as metallurgy, petroleum, chemical industry, and power plants. They are used as connecting wires for various electrical appliances, instruments and automatic devices under high temperature conditions and harsh environments (such as acid, alkali, and low temperature oil and water conditions). It is used in situations where the AC rated voltage is 450/750 volts and below control, monitoring and protection circuits. Oil-resistant unshielded flexible cables are a copper core PVC insulated PVC sheathed flexible cord oil-resistant cable.
Oil-resistant shielded flexible cables: Copper core PVC insulated PVC sheathed flexible wire shielded oil-resistant cables.
Oil-resistant shielded flexible cables are suitable for electronic computers and automation connection cables with a rated voltage of 500V and below that require high interference resistance. Cable ground core insulation The edge of the computer cable is made of K-type B-type low-density polyethylene with anti-oxidation performance. Polyethylene has high insulation resistance, good withstand voltage, low dielectric coefficient and low dielectric loss temperature and variable frequency. It can not only meet the requirements of transmission performance, but also ensure the service life of the cable.
In order to reduce the mutual crosstalk and external interference between the loops, the cable adopts a shielded structure. Cable shielding requirements are adopted according to different occasions: pair-pair combined shielding, pair-pair combined cable shielding, pair-pair combined shielding after total shielding and other methods. There are three types of shielding materials: round copper wire, copper tape, aluminum tape/plastic composite tape. The shielding pair and the shielding pair have good insulation performance. If the potential difference between the shielding pair and the shielding pair occurs during the use of the cable, the signal transmission quality will not be affected.
