  • High temperature cable. The heating temperature is 150℃ and the long term working temperature is 200℃.
  • High efficiency. The electric energy can be transformed to the thermal energy to deliver to the heating liquid.
  • Improve the working conditions and increase the oil production.
  • Prevent paraffin precipitation and lower the viscosity of the crude oil to reduce the sucker rod breaking.
  • High tensile strength and durability in a long working time.
  • Resistance to the high temperature and abrasion.


The heating cable can be used with the hollow sucker rod to form the hollow sucker rod electric heating device for oil exploitation of high pour point, high viscosity and high wax content.
