[0043] Example:
[0044] A constant temperature heat tracing carbon fiber continuous sucker rod includes a carbon fiber core 28, an electric heating belt A40 is arranged in the center of the carbon fiber core 28, and the carbon fibers constituting the carbon fiber core 28 are wrapped around the electric heating belt A40. The setting of the heating cable 40 can realize the constant temperature heating of the sucker rod, even if the sucker rod maintains a high and stable temperature, thereby preventing the paraffin in the crude oil from condensing on the sucker rod.
[0045] The carbon fiber core 28 is composed of 150 / 12K---242 / 12K carbon fibers bonded by epoxy resin carbon fiber bundles, and the carbon fiber tensile strength is greater than or equal to 4950MPa. 45. Winding glass fiber layer A29 and winding glass fiber layer B34, winding glass fiber layer B34 is covered with longitudinal glass fiber layer 30, and the outer wall of longitudinal glass fiber layer 30 is coated with...
