Explosion-proof self-regulating cable GTG-KSN up to +85 °C

Product Description

The GTG-KSN self-regulating low-temperature parallel heating cable is used to protect against freezing and maintain process temperatures up to +65°C for pipelines, tanks, automation facilities, and any other objects that require additional freeze protection.

For organic corrosive environments, it is recommended to use cables with a fluoropolymer sheath.

For weak inorganic media, it is recommended to use cables with a polyolefin sheath.

Scope: Hazardous areas of indoor and outdoor installations of classes 1 and 2 according to GOST IEC 60079-10-1-2013, hazardous areas of classes 21 and 22 according to GOST 31610.10-2-2017/IEC 60079-10-2.2015, normal.

Advantages

The given figures are intended only for preliminary estimation of the length of electric heating circuits.

For an accurate calculation, please contact ZAVOD GORELTEX CO. LTD.. To ensure safety and fire protection, a 30 mA RCD must be used.

If the design results in a higher earth leakage current, for devices with adjustable tripping current, the preferred tripping current level is 30 mA above the heating cable manufacturer's specified earth leakage current rating or the next available tripping current value for devices with non-adjustable tripping current, up to a maximum of 300 mA.
