The conductor of the product allows a long-term working temperature of 90 degrees and maintains an elastic state below 130 degrees. Compared with PVC insulated cables of the same cross-section, the intercepting flow can be increased by 25% and the specific gravity is 0.92/m3. The cable is light in weight and small in diameter. Easy installation, simple attachment, good heat resistance, no melting, chemical corrosion resistance, high mechanical strength and so on.
