Fog Type Suspension Insulator toughened Glass Insulator U70BP

Fog Type Suspension Insulator toughened Glass Insulator U70BP

Short Description:

Performance and application scenarios
Anti fouling glass insulators have the following advantages:
Good self-cleaning performance: not easy to accumulate dirt and easy to clean, the glass insulators running on the southern line are washed clean after rain
Strong stain resistance: In humid environments, anti fouling coatings can effectively prevent dirt from adhering and maintain insulation performance
Good resistance to arc and vibration: even after lightning burns, the new surface remains smooth and the mechanical strength is not affected
Long service life: After 35 years of operation, the mechanical and electrical performance remains basically unchanged without any aging phenomenon

High Voltage Insulator tempered glass insulator U70BP 70kN GLASS INSULATOR toughened glass insulators U70BP

The main difference between anti fouling glass insulators and standard glass insulators lies in the materials and manufacturing processes. ‌
The anti fouling glass insulator is covered with a layer of fluorocarbon coating on the glass surface, which has good moisture-proof and anti fouling functions. Standard glass insulators are made directly from ordinary glass materials without additional anti fouling coatings

Standard glass insulators have the following characteristics:
Simple manufacturing process: using ordinary glass materials directly without additional anti fouling coatings
Low cost: Due to the lack of complex coating processes, production costs are relatively low.

Maintenance and testing methods：
Anti fouling glass insulators have the characteristic of "zero value self rupture". When the insulation performance is lost, the glass umbrella shaped plate will burst and break, making it easy to detect and maintain
However, standard glass insulators require regular testing and maintenance, which incurs higher costs.

 

Structural composition:

Glass insulators are usually composed of iron caps, tempered glass pieces, and steel feet, which are bonded together with cement adhesive

Main types of glass insulator：

Glass insulator is including standard type, pollution resistant type, DC type, spherical type, aerodynamic type, ground wire type, and contact network for electrified railways

The Production process flow:

The production process of glass insulators in Jiangxi Huayao Electric Co.,Ltd is as follows:
Mix raw material=>melt glass liquid=>press to glass insulator shape=> tempering treatment=>cold and shock test=> Glue assembly=> routine test and other test=> Finished products package
Ingredients: Ingredients refer to the uniform mixing of different raw materials according to a certain ratio. 
Melting: Melting refers to the process of heating ingredients at high temperatures to form a uniform glass liquid.
Pressing: After melting and clarification, the glass liquid enters the pressing process through the feeding system, that is, the glass is hydraulically made into glass insulation parts, usually achieved through a fully automatic hydraulic forming machine. 

Tempering: Subsequently, the glass piece is subjected to tempering treatment, which means controlled cooling of the glass piece to obtain permanent surface press tress. The equipment involved in the tempering process includes temperature equalization furnaces, tempering machines, etc.

Cold and hot shock: Tempered glass pieces undergo cold and hot shock tests, using a special nickel sulfide treatment furnace and a special nickel sulfide elimination process to homogenize the glass pieces. The quality of the nickel sulfide removal process directly affects the important indicator of the glass insulator after operation - the self explosion rate.

Glue assembly: Use an assembly machine with steel foot positioning assistance to assemble and glue the insulator insulation parts, steel feet, and steel caps. This step requires attention to ensuring the coaxiality of the steel feet, insulation parts, and steel caps. Poor coaxiality can also lead to high self explosion rates. Inspection: Conduct a 50%

Tensile load test: Tensile load test on the glass insulators that have been glued together, check the height of the insulator structure, etc., to ensure that the insulators meet the standard requirements.

Finished products package: pack the goods according to customer request.

For overseas customers use export wooden box with fumigation seal.
For domestic customer orders use bamboo package
