The first electric melting furnace technology and automatic control system are adopted. The furnace temperature is stable within the range of + 1 C. The liquid level control is within the range of + 0.5 mm, which effectively improves the strength and electrical performance of each piece of glass.

The proportioning weighing device adopts three electronic sensor type ingredients. The static error of the ingredients is controlled within 0.2%, which ensures the accuracy of the glass formula. The raw material is mixed with forced mixer, and the uniformity of the mixture is over 98%.

Glass toughened by temperature treatment furnace, 20 station machine and special tempered tempering process effectively. In order to ensure the quality of the steel and the uniformity of the steel, the mechanical strength of the glass parts is ensured.

The accuracy of the weight of the material drops is controlled by + 10g, which ensures the stable shape of the glass parts. The glass forming is completed on the 12 station open die, 4 punch boring automatic hydraulic press, ensuring the umbrella shape and creepage distance of the product.   

The accuracy of the weight of the material drops is controlled by + 10g, which ensures the stable shape of the glass parts.

Formula design: introduction and absorption of foreign mature glass insulator formula, the application of the "neutralization effect" of alkali metal ions and the "suppression effect" of alkaline earth metal ions to make the best formula. Glass design: the head is designed for circular cylinder and surface thread, and stress concentration is avoided in the process of glass d...

The three jaw positioning mechanism, the vibration assembly machine and the steel foot positioning fixtures ensure the coaxality of the insulator fittings. The finished insulator is maintained at 60 C -70 C hot pool. After the completion of the maintenance, the 50% tensile load test is carried out according to the technological requirements, and the strength of the insulation structure is automati...

The products after tempering are subjected to three stage cold and heat impact test. The nickel sulfide special treatment furnace and special nickel sulfide elimination process are used to homogenize the glass parts, which reduces the self ignition rate of the insulator line.
