Fluorine plastic control cable use characteristics
Fluorine plastic control cable has oil, water, wear, acid and alkali resistance and a variety of corrosive gases, anti-aging, non-combustible and other excellent properties, suitable for metallurgy, electric power, petrochemical and other industries. Applicable to AC line voltage and below 450/750V electrical instrument cable and automatic control system transmission line.
Fluorine plastic control cable is suitable for the transmission line of the control voltage and the monitoring circuit of the AC rated voltage 450/750V and below, the connection line of the electrical instrument and the automatic control system. The product has excellent properties such as oil resistance, water resistance, abrasion resistance, various chemical reagents and acid base resistance, various corrosive gases, aging resistance, non-flammability, etc. This product is mainly applicable to power generation, metallurgy, petroleum, chemical and other industrial and mining enterprises at high temperature, Low temperature and acid, alkali, oil, water and corrosive gas in the harsh environment for electrical instrumentation and automation control system transmission line. Fluorine plastic insulated and sheathed high temperature resistant control cables are made of polyfluorinated ethylene propylene or modified PTFE material and have higher heat resistance than ordinary control cables.
Fluoroplastics control cable use characteristics: AC rated voltage: U0/U450/750KV; maximum operating temperature: Polyfluoroethylene (F46) insulation does not exceed 200 °C; soluble polytetrafluoroethylene (PFA) insulation does not exceed 260 °C; Minimum ambient temperature: PVC sheath: fixed laying -40 °C, non-fixed laying -15 °C; cable installation laying temperature should not be less than 0 °C (fluoroplastic, silicone rubber and nitrile sheathed cable not less than -25 °C); Cable allowable bending radius: The minimum non-armored cable is 6 times the cable diameter.
