Features and uses of fire-resistant control cable products: This product has high fire resistance, and will not be short-circuited or short-circuited in a certain period of time when it is directly burned by flame. Therefore, in case of fire, it is beneficial to reduce losses. Low-smoke halogen-free cable belongs to environmental protection cable, and is especially suitable for industries such as electric power, large buildings, railways and ships with high fire protection requirements.

Usage characteristics:

1.AC rated voltage: u0/u0.6/1kV.

2.Maximum long-term working temperature: 70℃ and 105℃ for flame-retardant PVC insulation and sheath; Fluoroplastic insulation and sheath at 200℃ and 260℃; XLPE insulation at 90℃; Low smoke halogen-free flame retardant polyolefin 70℃; Low smoke halogen-free flame retardant crosslinked polyolefin at 90℃ and 120℃.

3.Minimum ambient temperature: flame retardant PVC sheath: -40℃ for fixed laying and-15℃ for non-fixed laying; Fluoropolymer insulation and sheath: fixed laying at-60℃; Non-fixed laying -20℃.

4, cable installation and laying temperature is not lower than 0℃.

5.Recommended allowable bending radius for laying: the unarmored cable shall not be less than 6 times of the cable outer diameter; Armored cable shall not be less than 12 times of cable outer diameter; The cable with fluoroplastic insulation and sheath material shall not be less than 8 times of the cable outer diameter.
