Customerized Porcelain Strain Insulators / light gray glaze / OEM available
Description:
| ANSI CLASS | Tensile strength (kN) | Wet power frequency flashover voltage 50HZ(kV) | Height (mm) | Weight (kg) |
| Gy4 | 222 | 30 | 280 | 5.9 |
Our insulators have externally attached caps and bases. A highly engineered cementing system transfers the load uniformly from the hardware into the porcelain body. Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain. The body is glazed to add strength to improve surface appearance, and enhance clean-ability.
Features:
1. The insulation parts are made of midden-high aluminum porcelain C120 . the porcelain surface covered a layer of hard glaze , color brown , we can also produce such product with color white , grey or as per customer's specifications.
2. the material of locking device are stainless steel , its function is to guarantee insulator connection with related hardware very firmly .
3. Cementing material are Portland cement to assemble porcelain body and related cap . even after years of servicing , the cement still keep good performance.
Competitive advantage:
Reasonable insulation structure high reliability of interturn insulation.
Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.
Convenient transportation and flexible installation.
Low OSS. Low temperature rise. High mechanical strength, strong weather ability.
Outstanding crack resistance.
Low thermal expansion coefficient.
