The invention discloses a wave-regulating resistor and a manufacturing process thereof, belongs to the technical field of high voltage test equipment and aims to solve problems that the traditional wave-regulating resistor structure manufacturing process is not environmentally friendly, the employee's physical and mental health is difficult to guarantee, the manufacturing process is cumbersome, and production efficiency is low. The wave-regulating resistor mainly includes a base member and a packaging housing for packaging the base member, wherein the base member includes an epoxy plate framework, a conductive plate and a resistance wire, the packaging housing includes a hollow body and an end cap, and electronic potting glue integrally fixing the base member, the hollow body and the coveris potted in the packaging housing. The wave-regulating resistor is advantaged in that the structure is cleverly designed, the traditional design concept is broken, the structural mechanical strengthis very strong, the structure is very stable, product reliability is high, the service life is long, healthy and environmental protection is achieved, social benefits are very obvious, high quality and strong product consistency are achieved, the production processes are few, the production and processing speed is fast, manufacturing cost is low, the wave-regulating resistor can be used on a large scale, the market application prospect is good, and economic benefits are considerable.
