GBR Self-Regulating Heating Cable

Developed by Anhui Huanrui in line with international technical standards, GBR is a high-performance self-regulating heating cable designed for medium and high temperature industrial conditions. It maintains a steady operating temperature of 115°C continuously and withstands instantaneous thermal shock up to 155°C, suitable for working scenarios such as equipment steam purging.

Constructed with nickel-plated copper bus wires and fluoropolymer outer jacket, the cable is manufactured via advanced co-extrusion technology. It boasts excellent high-temperature oxidation resistance, stable conductivity and outstanding mechanical deformation resistance. Featuring self-regulating property, it automatically adjusts heating output according to ambient temperature to avoid overheating and achieve energy efficiency. Ideal for harsh environments including oil, gas, refining and fine chemical industries, it maintains stable performance with low attenuation and superior anti-aging capability, serving as a premium choice for medium and high temperature heat tracing systems.
