GRD type heat tracing cable is for deicing of roofs, gutters and drains. GRD cable is designed to withstand the long-term exposure to sunlight. The core is composed of infinite carbon particles which create a continuous path of conductive polymer extruded between two copper bus wires. It is self-regulating meaning it regulates its own output in response to the ambient temperature as electrical current flows through the core. It produces more heat if temperature drops and less heat if temperature rises. The cable cannot overheat and melt or damage temperature sensitive roof coatings thus providing a safe operation. The parallel feature of the cable allows it to be cut in the field to the exact length required.
